You repair asphalt using the “hot poultice” method. This is where the area around the defective asphalt is heated, then the perimeter cut using a hammer and bolster. Once the perimeter around the defective area is cut it is lifted carefully with a pick or a shovel. This old asphalt is placed in a wheelbarrow and removed from the site. The defective area is cleaned and dried if necessary.
Then, the perimeter joints are cleaned around the defective area and a break joint is formed. This break joint finished 10mm below the asphalt surface.
Next, sheathing felt is laid into the defective area. This is to allow for movement. Now new asphalt can be laid to replace the asphalt which was removed. A fusion joint is created between the old and the new asphalt to create a seamless finish. Once this asphalt has cooled off it can be painted with solar reflective paint to maximise the longevity of the asphalt.
Asphalt is a fantastic material as it can nearly always be repaired if it becomes defective. The way in which an asphalt repair is carried out is using the “hot poultice method”. You can find out more details about asphalt repairs by clicking the following link: Asphalt Repair
