Processing:

 

1. 

 

Slotting: the crack is too narrow, need to open a concave groove, the groove depth and width of typically 1-2cm.

 

 

2.

 

Cleaning: clean up the cracks with a broom or compressed air to remove dust and loose particles

 

 

3.

 

Preheating: use the hot air to heat the edge of cracks in order to remove moisture. Heating the edge temperature to 7 °C -18 °C, in order to facilitate the bonding of the material.

 

4.

 

Filling: pour ROADPHALT Filling Crack Sealant into the pavements' cracks evenly
