ABSTRACT:
The protection of roadway surface dressings against the initiation and the propagation of cracks is accomplished by interposition between the base layer and the surfacing layer of a binding layer consisting of a nonwoven geotextile interface impregnated with modified bituminous binders. The textile interface is a nonwoven fabric composed of continuous synthetic filaments of flat cross-section (width-to-thickness ratio of between 10/1 and 5/1), and are resistant to the temperatures of application of bitumen or of bituminous materials, have a low void index, are resistant to aromatic and aliphatic solvents, have a low compressibility, are deformable in the plane of laying and have a surface density preferably of between 100 grams and 300 grams per square meter. The modified bitumen is preferably based on styrene/butadiene/styrene copolymer and has characteristics such as: penetration 180/220, ring and ball 74.degree. C., penetration index 1.7, and is used in a quantity of between 300 grams and 800 grams per square meter.
