GEOCOMPOSITE FOR REINFORCING THE ASPHALTIC AND CEMENT CONCRETE FOR ROAD SURFACING AND PROCESS FOR MANUFACTURING THE SAME

摘要

The invention relates to a composite made up of glass yarns, polyesteric yarn interlaced geotextile impregnated with asphalt during the manufacturing thereof in order to reinforce the asphaltic and cement concrete road surfacing and to a process for manufacturing the same. According to the invention, the geocomposite comprises a polyester yarn interlaced material, when used for the first time, in a mixture with recovered polyester yarn from the chemical industry having a mass of 125 ...175 g/ square meter on a fabric underlayer of glass filament yarns and glass roving yarns with a mass of 135...270 g/ square meter impregnated with asphalt and having a tensile strength of 3...20 times higher, and the stretching of 4 ...20 times lower than the geotextiles, and the strength higher and the stretching of about 3 times lower than the majority of the geogrides and when impregnated with 350...400 g/ square meter asphalt and covered with a layer of 50 ...100 g/square meter limestone filler has uniform characteristics of the same size grade. According to the invention, the process for delaying the transmission of fissures and cracks in damaged road and motor road surfacing consists in priming the damaged surfacing with 0.65...1l/ square meter asphalt melt at a temperature of 160 ...170 degree C depending on the geocomposite type, spreading the composite interlayer over the priming, fixing it by passing once-twice the flat light compactor over it and finally making one or more asphalt reinforcing layers.
