AN ECONOMIC RESURFACING PROCESS FOR ASPHALTIC CONCRETE WEARING COURSES

UN PROCEDE ECONOMIQUE DE REFECTION DES COUCHES DE ROULEMENT EN BETON BITUMINEUX

Within the scope of the strengthening program, the direction Departementale de l'Equipement has been using the "regetherm" process, developed by the Salviam-Brun Company, for resurfacing the wearing course of a motorway which had not deteriorated structurally, but has simply suffered surface wear. The regetherm technique, utilising just one machine, heats and scarifies the mixture in situ, renovates it and finishes the surfacing with the addition of 35 to 60 kg/sq.m of new bituminous mixture after removing a certain quantity of old mixture (about 20 kg/sq.m). Already widely used in England and scandinavia, it is only at the innovation stage in France, and its adoption has been due essentially to the fact that giving the pavement a quality comparable to that obtained by strengthening, permits: appreciable economy relative to other processes; reduces inconvenience to motorway users; avoids any strengthening of the in-situ protection and, consequently avoids the raising of ancillary equipment and maintenance of clearance height under elevated sections. The paper emphasises the reasons for the choice of the process, defines it, details the precautions relating to its use and comments on the first technical and economic appreciations of the results obtained.
