WITH THE EXPERIENCE of everyday use, Dynapac has developed unique solutions to a new range of plates in six different size classes, from the small versatile lf50 to the large lf130 for heavy-duty applications.

FOR ASPHALT APPLICATIONS the lf75, lf80 and lf100 are equipped with a new water distribution system without pipes or sprinklers to clean, providing for un-equalled results for all types of asphalt jobs. The water consumption is easily optimized by means of a flow adjustment valve, hich is easily reached by the ope-rator. a large removable water tank, with a secured cap, makes refills quick, simple and less frequent.

THE BOTTOM PLATE is the most critical component of a forward plate for asphalt compaction. the Dynapac lf series has a new design of the bottom plate and its edges give a well-defined contact surface that will leave no marks on the surface.

FOR THE SMALL CONTRACTORS the Dynapac lf50 and lf60 forward plates are ideal when working in narrow trenches or at small jobs. Folded down they are easily transported between job-sites.

THE MACHINES ARE FAST, app. 20% faster than thei predecessors, and very manoeuvrable with a tight turning radius.

for tight and complicated spaces the handle can even be raised to a vertical operational position. the new Dynapac units have foldable handles providing for easy transportation and storage.

all plates have a wide array of optional equipment such as a protection frame suitable for rental applications, lifting handles etc making it possible to customize the machine.

ORIGINALLY DESIGNED for high compaction performance and lowest pos-sible vibration level, the new lf range of forward plates out performs its competitors with the low-ViB handle (vibration redu-cing handle) which allows for exceptionally low levels of hand-transmitted vibrations.

THE COMPACTASPHALT® method is revolutionising roadbuilding. With this method, patented in 1993 by Professor Elk Richter at Erfurt, Germany, and now recognised as standard practice, the binder and the wearing course are applied to the loadbearing layer one after the other in a single pass. Con-ventional roadbuilding involves two separate passes, with the wearing course being applied after the binder has cooled.

THE CONVENTIONAL met-hod poses problems here, espe-cially in bad weather. According to the official ZTV Asphalt’ regulations in Germany, these problems can be eliminated by using the Compactasphalt® method. The new method not only cuts construction time by half, helping to reduce motor-way congestion, it also brings tangible technical benefits. It

makes use of the heat in the thick binder layer that has just been laid to gain time for the compaction of the two upper layers. With the conventional paving method, the binder layer cools before the wearing course is applied. In bad weather this may lead to uneven compaction.

GOOD COMPACTION of the asphalt is crucial in roadbuilding, but the rollers take time to do their job. The cooling of the asphalt during compaction reduces the degree of compaction and with it the durability of the road surface.

“By laying the binder and the wearing course at the same time, we apply a total of twelve centi-metres of asphalt,” explains Ro-land Egervári, Product Specialist Pavers at Dynapac. “Because the applied asphalt is thicker, the use-ful compaction time is extended

by a factor of at least seven.” This is especially attractive for road-building in bad weather, when the asphalt temperature falls rapidly.

BECAUSE THE TWO layers are applied ‘hot-on-hot’, the Compact-asphalt® method also makes it possible to reduce the thickness of the uppermost layer to two centimetres, as opposed to four centimetres with the conventio-nal method. Since the wearing course mix is particularly costly, this means substantial savings for the contractor and ultimately for the taxpayer. Compared with the conventional method, Compact-asphalt® also gives better bonding between the individual layers, helping to prevent crack formation in the road surface.

ROAD SURFACES made of compacted asphalt last longer. On average, the loadbearing layer of a road needs to be replaced

4

after 40 to 50 years, the binder layer after 15 to 25 years and the wearing course after 10 to 15 years. So the wearing course needs replacing at least once during the normal service life of a binder layer.

“This isn’t the case with Compactasphalt®,” says Johan Arnberg, Vice President Paving & Recycling, Atlas Copco RCE Division. “With this method we can extend the service life of a wearing course to match that of the binder layer. So over the entire lifecycle of a road, the operator saves one re-laying every 25 years.”

THE EVALUATION OF a long-term trial with Compact-asphalt® on a stretch of road in the USA, provides firm evidence of the method’s benefits. The trial stretch, built with a Dynapac paver, was driven over continuously

by 60-tonne trucks, simulating an 18-year service life in just two years. The trial stretch showed not the slightest sign of fatigue in the form of tracks or cracks.

“The long-term maintenance of a road is an important cost factor for the owner,” says Egervári. “A client who pays attention to quality when a road is being built, and chooses

Compactasphalt®, can look forward to decades of trouble-free service.”

BY THE END of 2007, Dynapac machines had laid five million square metres of compacted asphalt in Germany, China, Poland and Rus-sia. In Germany, the company has supplied three large type F 300 CS road pavers for Compactasphalt®. This year, Dynapac will

be launching a modular extension of the tried-and-tested DF 145 CS paver. This will enable smaller construction firms to switch to paving with Compactasphalt® at a favourable cost. They only need to keep one paver, which can be quickly adapted as the need arises. This brings huge cost benefits, which firms can pass on to their clients – giving them a further argument in favour of Compactasphalt®.

FOR ROADBUILDING using the Compactasphalt® method, Dynapac offers the f300Cs high-performance paver. this machine has two hopper modules to hold the materials for the binder layer and the wearing course, and two screeds – a high-density screed for the binder layer and a normal screed for the wearing course. The two screeds are adjusted relative to each other to ensure that the thickness of the two layers is constant. The maximum working width of the finisher is 13.25 metres.

DYNAPAC IS CURRENTLY working on a modular extension of the Df 145 Cs series paver for working widths of 2.55 to 7.50 metres. so it will soon be possible to deploy this widely used paver for both the standard method and Compactasphalt®, allowing contractors to exploit their machines far more efficiently.

THE OPPORTUNITY to reduce the mix temperatures and therefore reduce pollutant emissions.

BY REDUCING the mixed good temperature at 10 °C, approx.0,23 l heating oil per one ton can be saved.

LONGER DURABILITY of the wearing course saves energy costs concerning the production of mixed good.

REDUCED ROAD REPAIR and maintenance works.

NO BITUMEN EMULSION is needed (which is sprayed on the binder layer in case of the conventional laying method)

AN ADDITIONAL REDUCTION of the asphalt binder course from 10 cm to 8 cm (highway projects) is possible.

and also deploys the machine on projects using the conven-tional method. “for large con-struction projects, Compac-tasphalt® is the method of the future,” says arne eichstaedt, head of Bunte’s Braunschweig office. “We’re convinced of the quality and also see the clear cost and time benefits of the method.”

IMPROVED LAYING qUALITY & HIGHER DURABILITY BY:Creating a thicker asphalt layer during laying and therefore an obviously signifi-cant extension of the period of time avai-lable for final compaction (t=k*d1,8) [1] and the possibility to optimise the degree of compaction, and positively influence the deformation resistance.t= time, k= constant, d= layer thickness the available time for compaction increases with the power of 1,8 of the actual layer thickness. By increasing the layer thickness from 4 cm to 12 cm, the available time for compaction is increased 7 times!

REDUCING THE INFLUENCE OF BAD WEATHER on the compaction properties of thin wearing courses by using the asphalt binder’s residual heat.

HIGH AND HOMOGENOUS DENSITY through the complete layer depth (wearing course and binder course)

EXCELLENT INTERLOCKING OF THE COURSES (Cut power 37kN) Due to its optimum bonding it will better withstand high vertical forces. this is main criteria for the long service life of the asphalt pavement. REDUCING THE APPEARANCE OF RUTS AND CRACKS as it is possible to take up higher vertical and horizontal for-ces due to optimum degrees of compac-tion and high layer adhesion (bonding and tight interlocking). BETTER DURABILITY can be expected due to a feasible high deformation resis-

tance and good interlocking of the layer, together with optimum air void content. IT IS POSSIBLE TO EXTEND THE PLANNED LIFETIME of the top layer, to be close to the lifetime of the binder course. ECONOMIC OPTIMISATION of the wearing course’s surface properties with regard to skid resistance, brightness and also the reduction of the course thickness. COST REDUCTION Due to a 50 % thickness reduction of the expensive wearing course. No bitumen emulsion is needed between the binder and wearing course. Significant reduction of paving times due to the simultaneous laying of both courses.

AS THE HOME OF the world famous TT motorcycle races, the Isle of Man has more than its fair share of road markings. During two weeks every year in June, the eyes of the world turn to the island – with a population of 80,000 and in the very middle of the Irish Sea between the UK mainland and Ireland – as the finest road racers on the planet pit their skills against the 37 miles of public roads that form the legendary TT mountain circuit.

THE TT FORTNIGHT, which attracts around 40,000 visitors each year, takes months of meticulous planning, and not least by the island’s Department of Transport, both in securing the route for bikes, which thunder through the tiny villages at speeds of 190mph, and in ensuring the safety of both riders and spectators.

THE ROUTE FOR the riders must be crystal clear at all times, be-cause at the speed they’re going, there’s no time for any indecision. So when the markings need to be removed, it’s essential that a completely smooth surface remains, posing no danger to the bikers.

THE THREE-WHEELED Dynapac PL 350Tplaner is easily mano-euvred and very flexible. For flash cutting along walls or curbs, the right-supporting wheel can easily be folded in. The Isle of Man machine was equipped with a special micro milling drum, containing 117 bits, compared to the standard 38, spaced at intervals of 3 mm as opposed to the conventional 12mm.“For demarcation work a micro milling drum is essential,” explainedDynapac technician Marco Dahms, who provided training for the De-partment of Transport’s maintenance team. “The main aim is to completely avoid damaging the asphalt or concrete pavement.”

IN ADDITION, to avoid a sharp edge at the sides of the demarcationarea, the drum is slightly offset by 1 or 2 mm at the edges – althoughvery flat across its 30 cm surface. This is essential in avoiding anydanger to the high-speed bikes.“Another important feature, and a real benefit on the PL350T, is thatbecause of the larger drum diameter, standard bit holder blocks can beused,” Mr Dahms added. “Other drums with smaller diameters cannotaccommodate the standard bit system, which means the Dynapac bitslast approximately four times longer than competing drums whichalways have to use the mini-bits.”

THE DYNAPAC’S additional 600 kg of ballast on top of the cutterhousing ensures minimum vibration during milling operations anda much smother and uniform result.“We have been using standard blasting equipment to remove roadmarkings up to now, but this was a highly manual operation, and atbest we were able to remove a stretch of just a few metres in a singleday,” said Department of Transport Engineering Works assistantengineer Kerrin Wells. “We were very impressed with the trialsof the machine, and look forward to greatly improving the standard oflining removal and renewal. We plan to use the machine on a stretchof the TT course immediately after this year’s event is over.”

FOCUSING ON PURCHASE price alone, when buying road construction equip-ment can prove to be very expensive. Why is that? Well, when calculating the to-tal costs of owning and running a machine, there are several other parameters that must be taken into account. Costs for service and maintenance, fuel consumption, operator wages, second hand value and machine up-time, are parameters that have a big impact on the real cost of ownership.

stand and control all costs and to see the true cost of ownership, a new easy-to-use tool ihas been launched for all roller models; Dynapac CostCtrl. With Dynapac CostCtrl you can easily calculate all the different parameters that drive costs. Used in combination with Pave-Comp or CompBase optimization tools you can be in full control of your complete cost picture. To learn more about Dynapac CostCtrl, please get in touch with your local Dynapac sales engineer or visit www.dynapac.com/ costctrl.

WHEN WE ASK our customers what matters most to them with their Dynapac equipment, the answer is clear: reliability! Reliability is also a remedy for keeping major cost drivers at a low level throughout the lifetime of a machine. In this perspective, the actual purchase price becomes less important and to pay a premium for good performance and low downtime can be very well invested money.

Visionary boardw i t h t h e f u t u r e i N m i N D

FREDRIK ÅKESSON, head of ihCC recently initiated Dynapac VisionaryBoard; a forum for discussing trends,techniques and new discoveries in road construction. The first meeting was held in November 2008 in stockholm.

Fredrik why have you initiated theDynapac Visionary Board?-as one of the leading manufacturers in the road construction industry, we must keep up to date with the latest develop-ments in the academic world as well as demands from contractors and require-ments from authorities.

What was on the agenda during thefirst meeting?-this time focus was on discussing chal-lenges and opportunities in infrastructureprojects from an academic researchviewpoint. participating in the board

were professors from universities inpoland, italy, Germany and sweden.

What was the outcome of yourdiscussions?- one common point from all participants was a clear focus on quality improve-ments. higher quality will, apart from the increased ride quality and safety, also reduce the environmental impact. higher quality means longer lifetime and reduced need for rehabilitation and renovation of the road network. the fe-wer times deteriorated wearing courses needs to be removed and replaced, the fewer traffic disruptions will occur. Less and less energy will be spent on mixing asphalt etc.

Then how can higher quality beachieved?- there are different ways to reach qua-

In which way do you see trends leading the asphalt (Road) construction industry in the short term?The focus is increasingly on warm and cold asphalt technology for new pavements and well as in-place recycling of existing pavements. This is driven primarily by increased cost of energy and the need for reducing CO2 emissions. There is also an ever increased pressure to recycle not just old pavements but other materials such as truck tyre rubber into asphalt pavements. There also appears to be an emerging reduction in the supply of bitumen that is driven by the oil companies developing

questions& Answers

lity improvement, ranging from reduced temperature in the asphalt mixes to improved practices in the construction phase. improving the skill of operators and giving them proper tools to evaluate the progress of paving and compaction, was also considered important. we have a number of projects ongoing to achieve these goals. several cooperationinitiatives have been taken that spanover all steps in the asphalt industry.everything from aggregate and binder properties, over mix design and ma-nufacturing as well as transportation, paving and compaction of asphalt mixes will be evaluated.

What will be the next step forDynapac Visionary Board?-the Visionary Board will continue tocooperate and interact with differentstakeholders.

increasingly innovative technologies to get higher value products out of each barrel of oil. The reduced supply of bitumen has also led to more variability of bitumen sources than previously, causing problems for agencies and contractors alike. Public agencies are also gradually moving toward performance-based specifications, percent within limit specifications, and warranty projects. This means that new compaction technologies, sometimes referred to as “intelligent compaction” will be increasingly more important in providing a more homogeneous final compacted pavement layers. Finally, there is a strong trend toward the use of polymer modification to increase the life of pavements. Would this have any impact in the way road construction equipment is designed or used? (in which way?)The focus on cold and warm in-place pavement recycling technologies has already led to new innovations in paving equipment where steam is introduced into the bitumen in order to cause the bitumen to foam. There are also a number of emerging technologies that allow for the manipulation of binder viscosity and thus lower mixing and paving temperatures through chemical modification. Similarly, the focus on performance-related specifi-cations, percent within limit specifications, and warranty projects is leading to an overall increased pressure to increase the quality of paving jobs. Seg-regation is now being recognized as a problem that can be fixed through good paving and compaction practices. There are likely going to be new types of compactors shortly that further minimize segregation problems and promote homogeneity of air void distributions within the compacted layer. Finally, we will see much wider use and further development of compactors with some kind of “intelligent compaction” technologies that allow for a reduction in the variability of the compacted pavement and thus increased pavement life.

SINCE DYNAPAC became part of the at-las Copco Group in 2007, it has been on the agenda to consolidate and integrate the points of distribution. ptD is one of atlas Copco’s state-of-the-art distribution centres and is well known for a high level of customer satisfaction.

per hörner, Vice president for purchasingand Logistics, sees great benefits for bothcustomers and group companies.“this will give us an increased service level, higher efficiency and better availa-bility of our products,” he says.

TRANSFERRING the distribution of light compaction and concrete equipment and spares to Belgium will allow the factories to focus on their core activity, production. Deliveries for the aftermarket are also part of the new distribution scheme, with all shipments being sent from ptD in hoeselt. Centralised distribution will lead to better service and efficiency.

customer will remain as it is today, and we are strengthening our back-office functions to better support our customer centres and distributors,” per hörner says.

THE LONG-TERM AIM is to have distribu-tion centers in europe, asia and the ame-ricas. Europe is first, but changes are in the pipeline for North america. Distribution from the factory in San Antonio, Texas, will be moved to the atlas Copco distribution centre in Allen, Texas. Companies in Ca-nada and Mexico are next in line to benefit from this reorganisation, with all shipments being delivered from Allen, Texas.

DESPITE THE FACT that ptD is a sepa-rate company, it is a fully owned by atlas Copco and a well integrated part of the day-to-day operations.“it is important to understand that we are a very active partner in this system. we are represented on the board of ptD and share responsibility for the hoeselt operation,” Per Hörner explains.

IMPLEMENTATION OF the european distribution changes, will be completed by august 2009. from a customer point of view, the change will have no noticeable effect on the way orders are placed. “the first line of support interacting with the
