摘要

A) the process of thermorecyclage in place of a layer of the roadway in the draining mix having a percentage void important, especially greater than 20%, over a thickness of approximately between 2 and 8 cm, & br / b) is characterized in that it heats the road or track to be processed at least over the entire width, to a mean temperature of the order of 130 to 160degré c with the aid of a known machine as - same equipped with infrared radiant panels fed to the propane, panels reflecting the infrared wave and spaces nonheated arranged and rotated so as to guarantee a slow and gradual heating of the roadway, on the thickness to be treated, without any risk of burning at the surface, is spread on the surface of the roadway, approximately 5 to 20% by weight of a corrector granular material is chosen so as to correct the grain size curve of the coated products aging, modified by addition of fine décohésionne the layer is heated, the mixing of the materials décohésionnés by injecting simultaneously 0,1 to 2% by weight of a binder supply to the base of the bitumen, it distributes the recycled mix on the roadway, and it is compact that - treatment of a conventional manner.
