CONSTRUCTION & MATERIALS

Intelligent Compaction (IC) uses modern vibratory rollers equipped with an integrated measurement system to provide real-time monitoring and facilitate timely adjustments to the compaction process.

IC increases productivity and improves in-place density of pavement materials. The integrated measurement technology provides operators with the ability to map and identify weak support areas for corrective actions and maintain consistent rolling patterns under lower visibility conditions, such as night paving operations. IC can minimize spot failures, extend pavement service life and reduce highway repair and maintenance costs.

Safety EdgeSM uses a wedge shaped attachment to paving equipment to create a sloped 30 degree angle edge to the roadway. Safety EdgeSM requires less than 1% of additional asphalt and can be implemented quickly at a low cost. Since the technique was introduced, more than 200 construction projects have incorporated Safety EdgeSM into roadway paving.

PennDOT issued Strike-Off Letter 481-13-02 making a new Standard Special Provision for inclusion of a Safety EdgeSM detail in the placement of bituminous concrete pavements.

The STIC and TAGs have advanced innovations to improve project design, construction, maintenance, and safety and operations. Two construction & materials innovations underway are highlighted below.

Traffic Incident Management (TIM) Responder Training

A training program that focuses on a response effort to protect motorists and responders while minimizing the impact on traffic flow. Efforts include detecting, verifying and responding to incidents; clearing the incident scene; and restoring traffic flow.

Leads to faster incident response and clearance, saving lives, time, and money. It could also lead to fewer secondary crashes resulting from the original incident and less exposure to moving traffic while the incident is resolved.

Warm MixAsphalt (WMA)

A technique that allows asphalt to be produced and placed on the road at lower temperatures compared to the usual hot mix method.

Reduces paving costs, extends the paving season, improves asphalt compaction, allows asphalt to be hauled longer distances, and improves working conditions.

For more information on any of the innovations, please contact the PennDOT STIC office at [email protected].

Maintenance Innovations


High Friction Surface Treatments (HFST) uses high-quality, wear-resistant aggregates to increase friction on pavement. The treatment can be applied to target areas, such as curves, steep grades, and intersection approaches, with minimal impact to traffic. HFST increasesroad-surface skid resistance and water draining, which reduces crashes, injuries and fatalities on curves and intersections. Application of the treatment on an intersection curve inDistrict 5-0 reduced wet-pavement-related crashes from twenty in ten years to zero in the six years since treatment installation.

HFST deployment is in progress and PennDOT will be deploying the treatment at additional locations throughout the State that would benefit from this innovative technology.
