SERIES 700 ROAD PAVEMENTS – GENERAL

770 AR JOINTS IN EXISTING CONCRETE CARRIAGEWAY General 1. All longitudinal and transverse joints to be sealed, shall be

sealed using one of the hot applied sealants as described in Clause 1017.

Joint Removal, Preparation and Saw Cutting 2. Joint sealant removal shall be carried out such that the existing

joint shall be completely removed without damaging the joint arrises.

3. The method of cleaning out joints shall be approved by the Overseeing Organisation

4. If spalling occurs or the angle of the former is greater than 10 degrees the joint sealing groove shall be sawn wider and perpendicular to the surface to encompass the defects up to a maximum width, including any chamfer, of 40mm for transverse joints and 25mm for longitudinal joints. If the spalling cannot be so eliminated, then the arris shall be repaired by one of the repair systems in the Contract as shown on the Drawings.

5. The sides of the joint sealing groove shall be scoured by dry abrasive blasting.

6. All grooves shall be cleaned of any dirt or loose material by blasting with compressed air which has been made oil free by filtering through a suitable coalescing filter. Particular attention should be made to prevent dust and abrasions being lodged in the joint crack.

7. The joints shall be allowed to dry, or a hot compressed air lance may be applied to the joint to remove all traces of moisture/water prior to priming and sealing. The Contractor shall ensure that no damage is done to the existing concrete during drying operations.

8. Cavities found in honeycombed concrete shall be filled prior to the application of joint sealant with approved filler.

9. Compressible caulking material, debonding strip or tape cord compatible with the sealant, of a suitable size to fill the width of the sealing grove shall be firmly packed or stuck in the bottom of the sealing groove to such a depth so as to provide the correct depth of seal as described in Table 7/70 with the top of the seal at the correct depth below the surface of the concrete.

10. If joint grooves are not initially constructed to provide the minimum dimensions for the seals they shall be enlarged by sawing.

Saw cutting shall be carried out such that the cut joint shall be formed with sides parallel throughout the depth and perpendicular to the road surface.




11. The permitted tolerance for the new cutting shall be:- width = + 1mm or – 1mm

depth = + 2mm or – 2 mm 12. Slurry or dust from saw cutting operations shall not be

permitted onto the adjacent trafficked lanes, or allowed to enter adjoining filter drains. All dust and slurry shall be removed from the work area at the end of each working session.

Sealing with Applied Sealants 13. An appropriate primer for sealant shall be used and it shall be

applied in accordance with the manufacturer’s recommendations, the primer incorporating a fugitive dye. The sealant shall be applied within the minimum and maximum drying times of the primer recommended by the manufacturer. Priming and sealing with applied sealants shall not be carried out when the naturally occurring temperature in the joint groove to be sealed is below 7oC.

14 When sealing operations are carried out near the lower air temperature limit, cold surfaces of exposed joints may cause rapid chilling of the hot applied sealant. To help compensate for this hot applied sealants shall be heated to their safe upper temperature limits for application as specified by their respective manufacturers.

15. Sealants shall be heated in and applied from a thermostatically controlled, indirectly heated dispenser with a recirculating pump. The sealants shall not be heated to a temperature higher than the safe heating temperature nor for a period longer than the safe heating period, both as specified by the manufacturer. The dispenser shall be cleaned out at the end of each day and reheated material shall not be used.

Testing of Applied Sealants 16. Independent certificates shall be supplied, which are not

more than six months old, stating that the sealant complies with the relevant standard in Clause 1017. Hot applied sealant shall be sampled at the rate and checked for dimensions as in BS 2499: Part 2.

1.0 kg/m²

2. The surface of any existing pavement layer that is to be overlaid, whether directly with the membrane, or with a regulating course onto which the membrane will subsequently be laid, shall receive the following treatment.

(a) All cracks of width greater than 3mm shall be blown clean and dry with hot compressed air and filled with 60 - 80 pen grade filled bitumen incorporating 70 - 75% Limestone filler, using a screed box not exceeding 50mm wide.

(b) All potholes, or fretted areas shall be filled with regulating material of aggregate size appropriate for the depth of material laid.

(c) The minimum surface temperature shall be 5°C, and the surface shall be dry and swept free from dirt, oil, vegetation and other debris, by mechanical broom.

3. The binder shall be either 200 pen bitumen maintained in a tanker/spray

at 160ºC ± 5ºC and sprayed at a rate of 1.0 l/m2 ± 0.1 l/m2 or polymer modified emulsion binder containing at least 62% bitumen sprayed at

1.4 l/m2 ± 0.15 l/m2. If the surface is porous/pervious the rate shall be increased, with the agreement of the Overseeing Organisation, to allow for the binder lost into the surface. The binder shall be sprayed uniformly over the whole area on which the fabric is to be laid, plus 150mm at each side using pressure jets specifically designed and calibrated for the purpose. Hot bitumen shall only be sprayed on a dry surface.


4. The fabric shall be laid out mechanically under sufficient light tension to ensure no wrinkling. Should wrinkling occur inadvertently the fold shall be slit and laid flat, permitting only a double thickness of material. Transverse joints shall be lapped in the direction of the paving but not exceeding 150 mm. Longitudinal laps shall be in the range 100 mm - 250 mm. All fabric must be bonded to the substrate with bitumen, and the Overseeing Organisation may permit additional bitumen to be placed manually to ensure this. The fabric shall be brushed with a stiff broom over its whole surface to ensure it is in contact with the bitumen film.

5. The surface of the fabric shall be rolled with a rubber coated drum vibroll or pneumatic tyred roller immediately after laying the fabric until intimate contact between the fabric and the surface upon which it is laid has been achieved.

6. The fabric may be overlaid immediately, if hot bitumen binder or chemically set bitumen emulsion (e.g. Nybreak) is used. For other bitumen emulsion a waiting period of 48 hours is required.

7. The fabric may be overlaid whilst wet, but all standing water shall be removed.

8 The fabric shall not be exposed to direct sunlight for a cumulative period exceeding 2 weeks prior to its being overlaid and shall be stored in accordance with the manufacturer's instructions.

9. Construction and emergency traffic may run on the fabric immediately after laying. However, it must be ensured that damage is not caused to the membrane by vehicles turning, braking etc. and it must also be ensured that the membrane is kept clean of mud or other detritus. If damage occurs the affected area shall be removed and replaced. If the surface of the fabric becomes tacky with bitumen during construction, this may be blotted with sand to prevent spreading and pick-up of the fabric. Excess sand shall be removed by sweeping before overlaying

10. The material covering the membrane shall be laid and compacted at a temperature in the range of 95°C - 145°C.

3. Inspection of Frames and Covers

If, in the opinion of the BT representative, the existing frame and cover(s) is not fit for re-levelling, they shall be replaced by the appropriate BT standard item. Where a frame and cover(s) is unsuitable and the replacement item is larger than the existing chamber (walls or shaft), then information for recommended modifications to the chamber will be supplied by BT.

4. Re-Levelling Frames and Covers in the Footway or Verge

Once the cover(s) and cross piece(s) are removed, remove the frame from the chamber. Prepare the frame, if applicable, for reuse by removing all the old bedding material, debris and rust. Remove all existing bedding material from the uppermost surfaces of the chamber (walls or shaft) to leave a clean dry surface.

All brickwork that the frame is to be bedded on must be sound and if necessary, removed, re-bedded or re-pointed.

If the change in level is less than 25mm then either: Place the frame in position level with the surface by using packing pieces under each corner of the frame. All voids under the frame shall be filled with cement mortar and any excess mortar shall be neatly trowelled and struck off in line with the inside of the frame.

Or A thick bed of cement mortar shall be trowelled around the uppermost surface of the chamber (walls or shaft) and the frame tamped and bedded on the mortar so the frame is level with the surface. All voids under the frame shall be filled with cement mortar and any excess mortar shall be neatly trowelled and struck off in line with the inside of the frame.

5. Re-Levelling Frames and Covers in the Carriageway

The work shall be carried out using quick setting materials in order to allow completion of the work and reopening of the carriageway to traffic within a working day.

(a) Materials

(i) Resin Mortar

This is a three component, quick setting, resin compound comprising a translucent liquid resin, a white powder hardener and a sand filler. The complete pack shall be readily divisible into two half packs.

Once the hardener has been added, the mortar will have a working life of 20 minutes and the initial set will take place after approximately 30 minutes.

Clause, Table or Figure No.


(ii) Resin Bedding This is a three component, quick setting, resin compound comprising a translucent liquid resin, a white powder hardener and a heat absorbing filler. The complete pack shall be readily divisible into two half packs. Once the hardener has been added the mortar will have a working life of 20 minutes and the initial set will take place after approximately 30 minutes.

(b) Method If the original frame and cover is to be reused all covers shall be marked so that when replaced they occupy the same position as they did before removal.

If a new frame and cover is to be used refer to paragraph 3 above.

Remove the covers and excavate an area around the frame approximately 150mm wide, and to the depth of the frame taking care not to damage the chamber (walls or shaft). Remove the cover and prepare it for reuse if applicable.

Prepare the surface of the chamber (walls or shaft) at 165mm below the carriageway surface by cutting back or building up as described in paragraph 4. If building up by engineering bricks or tiles being bonded with resin mortar the gap between the frame and the chamber to be between 12mm and 25mm. The finished surface must be free from debris and any water deposits.

Locate the frame square in the chamber (walls or shaft) and level it with the carriageway surface by supporting it in each corner with broken tiles or other suitable material.

On the inside of the chamber, face off the gap under the frame and chamber with a thin bead of resin mortar, this will act as an inside shutter to contain the resin bedding.

Allow the mortar an initial set, which is indicated when it feels firm against finger pressure, then mix and pour the resin bedding around the frame until it just covers the lower frame flange (as shown in Drawing No. ER 101).





Allow a minimum of 2 hours to elapse before replacing the cover(s). It is important not to disturb the frame before this time period in any way. Check that the covers do not rock or foul the chamber (walls or shaft) or removable grids. If the covers rock take whatever corrective action is necessary and ensure that the cover is free from debris and/or resin material.

6. Safety When mixing and using resin bedding or resin mortar the following precautions must be observed:-

(a) Barrier cream shall be used for exposed hands and forearms.

(b) Disposable gloves should be worn.

(c) Mixing should be in a well ventilated, but wind shielded location.

(d) Eyeshields should be worn during mixing as the white powdered hardener contains a small proportion of peroxide.

(e) An orignasal type respirator, fitted with a dust and organic vapour filter should be worn.

(f) The disposal of all waste material, cans and plastic bags must be at an approved tip, the details of which can be obtained from the Local Authority.

7. Security To enhance security against the unauthorised entry of BT chambers, when Lockable Frames and Covers are renewed, relevelled or replaced, the Frame shall be bedded on the shaft or chamber, with Resin Bedding.

8. Reinstatement Prior to reinstatement in a bituminous surface, the sides of the excavation and the outside of the frame shall be primed with bitumen emulsion and the space surrounding the frame reinstated with Rolled Asphalt Surface Course (Design Mix) to Clause 911. Where only Resin Materials have been used, for re-levelling frames and covers, then reinstatement can commence 2 hours after the last batch of material has been placed.
