The opening and the closure of cracks because of the thermal variations of structures with concrete of cement or lean mix.
Two manners to handle this problem :
Create a plan of sliding with bitumen between the cracked part and the new asphalt layer like a sand asphalt. Rotaflex ® 816 SL has to guarantee the thickness of the bitumen. The mesh of the grid are tightened so that the aggregate does not pass through. The grid strengthens the bitumeuse membrane. The cracks can then put 5 times longer to propagate to the surface. Moreover, this thin bituminous membrane in the case of the textiles improves the waterproofing of the roadway.
