A COMBINATION OF MODIFIED BITUMEN EMULSIONS AND GEOTEXTILES AS A SOLUTION TO THE PROBLEM OF PAVEMENT CRACKING

Cracking on road surfaces is one of the problems which nowadays most concerns road engineers, and in particular, those cracks which originated by reflexion into the road surface of hydraulic and/or thermal cracks coming from the underlayers with hydraulic binders. Among other techniques to fight this problem there are the so called "Interlaying Techniques" of SAMI (Stress Absorbing Membrane Interlayer), outposting among them the membrane consisting of the components: GEOTEXTILE PLUS MODIFIED BITUMEN EMULSION. This paper describes the following system: the characteristics which have to fulfill the geotextile and emulsion components, especially their residual binders characteristics; and the importance of the emulsion dosification. The installation procedure and the different laboratory tests which allow the evaluation of the system's quality are described. The conclusion shows that optimizing all mentioned parameters, the anti-cracking system of an impregnated geotextile with a cationic emulsion of modified bitumen is one of the most effective systems in the fight against road cracking.
