Drive Repair Asphalt is a 6mm grade ready to use cold lay asphalt for instant, temporary repairs to domestic driveways and paths. A washed sand conforming to BS EN 13139 Aggregates for mortar. The typical moisture content is 5%.

PREPARATION

• Ensure the area to be repaired is dry and edges are solid/sound and not friable.
• Sweep the area and remove all debris including weeds and roots.

APPLICATION

• Use a rake or spade to spread the Drive Repair Asphalt to the required thickness, remembering to be slightly proud of the hole to allow for compaction. 
• Use a flat heavy object for ‘tamping’ such as a tamper or mechanical plate compactor.
• Wet the tamper frequently to stop the Drive Repair Asphalt sticking to the tool and ‘picking up’. 
• NOTE: When repairing deep potholes (greater than 30mm) lay the Drive Repair Asphalt in two stages. Ensuring the first layer is fully compacted before spreading the next layer and compacting to the required finished surface level.

FINISHING

• In warm weather it can be beneficial to lightly dust a little dry sand over the surface after compaction to help reduce ‘picking up’ of the fresh material as it sets.

COVERAGE

• The coverage rate of Heidelberg Materials Drive Repair Asphalt is approximately 0.4m2 per bag, when compacted to a depth of 30mm.

CONDITIONS OF USE

• Not suitable for heavily trafficked areas, or areas exposed to high stress such as turning.
• Protect the newly laid surface from caravan legs, motorbike kickstands and other similar high loadings.
• Do not place heavy and sharp objects on the newly laid surface.
• Protect the newly laid surface from vehicle tyres and power steering action.
• Timber sheets can spread loading of vehicle tyres but will also reduce oxidation which is required for the product to harden. Therefore, do not leave permanently covered as this will extend the time taken to fully harden.
• Drive Repair Asphalt should be placed within the temperature range of 5°C to 30°C.
• The workability of the Drive Repair Asphalt will improve if the outside temperature is above 10°C.
• The material may be prone to marking and deformation during early life and warm conditions.
• The time taken to fully harden will depend on the degree of compaction and ambient conditions.
• Surface finish can be improved by further tamping.
• After prolonged storage or in cold conditions, it may be necessary to expose the bag of the Drive Repair Asphalt to direct sunlight for 1-2 hours prior to opening to loosen the material and restore workability.

STORAGE

• Bags should be stored unopened, clear of the ground, under cover and protected from extreme temperatures. Heidelberg Materials Drive Repair Asphalt can be stored for periods in excess of 6 months.
