Mastic Asphalt
Home

Asphalt has been diamond cut and stripped out either side of expansion joint which has also been removed.
First coat asphalt skirting is being formed prior to new expansion joint being fitted
Access was required over the bridge deck, meaning that the new joint had to be installed over 2 days
Heating up the old asphalt paving and cleaning ready to make a new joint.
New epoxy bed has been laid ready to receive new expansion joint.
First coat roofing asphalt is laid flush with new bed
Expansion joint has been fitted and the heavily gritted asphalt paving is being laid
Note how asphalt seals onto expansion joint membrane (light colour)

Asphalt paving is tipped from limestone dust lined metal bucket.

Membrane can be seen rolled up in background as it was installed in one piece.

One side of joint is left to cool while other side is being laid
Before asphalt has cooled completly a special roller is used to form indentations, this enables better traction for vehicles as well as giving a patterned finish to the asphalt
Using a crimping roller, note the dust to prevent the asphalt sticking to the roller.
