Rutting of Bituminous Concrete

Under the traffic action, pavement crumbling may occur rapidly, which leads to severe impairments that are reflected on the surface layers (9) Rutting, cracking, substances rejection, polishing and puUing out the aggregates on surface. This situation often needs a renovation of the surface layers. 

The use of local materials for pavement design has been assessed. Recycling of bituminous substances is one of the relevant solutions. This method has the advantage of reusing budding materials by mixing them with a proportion of refined ones to achieve the required performance (9).
