The use of geosynthetics in rehabilitating flexible pavements has substantially expanded since the mid-seventies. These materials have a number of advantages that motivate their demand at present. The use of geosynthetics in rehabilitation is based on its ability to resist deformation, attenuating fissures and cracks that flexible pavements could present. Two experiments have been done to simulate the process of placing the geosynthetics in the interlayer area. The process consists of pouring on the spread geosynthetics a layer of hot bituminous mix between 135-165 °C. The thermal analysis of the results shows a significant performance of polyester (PS), compared to polypropylene (PP), in future applications for the rehabilitation of flexible pavements.
