Definitions

  • this clogging phenomenon is particularly rapid at the level of the emergency stop lane and slow lanes: in fact, the sections of motorways typically present, between the central reservation and the shoulder, a slope of about 2.5% from which there results a transverse flow of precipitation water from the expressway to the emergency lane; this causes entrainment of the impurities which collect at the level of the emergency stop strip to fill in the gaps little by little.
  • This clogging phenomenon is accelerated by the "de-icing" salts used in winter which always contain insoluble impurities in addition to those linked to atmospheric pollution.
  • thermorecycling machine proper one and preferably two mounted preheating frames. on tires and also fitted with radiant panels, reflective panels and non-heating neutral spaces.
  • the decohesioning step can advantageously be implemented using a transverse rotary cutter for conventional decohesioning associated, if necessary, with a rotating vertical claw allowing decohesive the longitudinal joints, on either side of the roadway or track to be treated.
  • bitumen dosage should be limited to around 4.5 to 5% by weight to avoid obtaining fluid mixes; such dosages make it possible to obtain bonding of the grains, but the fatigue resistance of such coated materials is low and their lifetime limited.
  • bitumen film subjected to the action of air, risks aging particularly quickly.
  • draining mixes called “bitumen-rubber” have been developed in recent years consisting of aggregates coated in a binder mainly consisting of a mixture of bitumen and a reclaimed rubber crumb, and whose performances have been particularly interesting.
  • draining mix "Drainochape” (registered trademark) which is constituted by the association of a granular structure and about 6 to 7% by weight of the binder
  • Flexochape (registered trademark) obtained by mixing a selected bitumen of class 80/100 with 10 to 20% by weight of a rubber crumb in the presence of a compatibilizing oil and a catalyst.
  • the granularity of the basic structure is defined by the ratio d / D in which d corresponds to the particles of smaller diameter and D to the particles of larger diameter.
  • bitumen-rubber coated distinguish in particular by a very high cohesiveness, a great flexibility at low temperature, a strong resistance to rutting and a remarkable resistance to aging linked to the absence of thinner and to the presence of antioxidant elements in the crumb.
  • the curves appearing in appendix 2 represent, by way of example, the particle size analysis of a surface course of asphalt pavement "Drainochape" (registered trademark) on the one hand, after aging (curve 1 in dotted lines) and, on the other hand, after thermoregeneration and addition of 7.5% of a granular corrective material with a granularity equal to 6/10 mm and of 0.3% of filler binder, in accordance with the invention (curve 2).
  • thermorecycled mix The characteristics of the thermorecycled mix were analyzed using a gyratory shear press (type LCPC).
  • the compactness measured respectively at 1 gyration and 200 gyrations were found to be 68.2 and 79.5 respectively, and the percentage of vacuum measured during this test was found to be 20.5%, which corresponded to a value very close to its initial value.
  • the Cantabro test also made it possible to prove that the cohesion of the binder at 20 ° C was also extremely close to its initial value.
