How we do surface dressing
All preparation is carried out if there is a current surface which is just showing signs of fatigue and needs a protective surface coat we will just thoroughly clean the surface removing all unwanted debris and defects. However if it requires kerbs or a sub base this is usually carried out the day before. At this stage we can widen roads, create new roads, lay recycled road plannings, install kerb edging to act as a retainer or decorative feature.
Once all preparation work is completed we would move onto the installing the surface. A k-170 polymer reinforced bitumen liquid is heated to 80 degrees and sprayed onto the surface. This seals the surface preventing water penetrating into the surface causing damage. This also forms a bond for the aggregate of choice followed.
A double washed Aggregate of your choice is applied directly to the hot liquid , the aggregate is compacted into the hot k-170 bitumen liquid to ensure proper embedment. Leaving a final country finish which will look good for the years ahead.
