PLASTIC REINFORCEMENT FOR BITUMINOUS MIXTURES

POUR UN SYSTEME D'ARMATURE PLASTIQUE DANS LES ENROBES HYDROCARBONES.

A new application for the use of plastic household refuse is described: it can be used,in the form of strips, to reinforce asphaltic concrete. The various aspects of the technique are studied: shape of reinforcement, nature of plastic refuse, nature of the binder. The addition of plastic refuse can have two effects: binding effect if the polymer is partially soluble in the binder (this is the case of tar and pvc); reinforcing effect which is a function of the length of the refuse strips added. Hot-coated materials markedly improve in mechanical strength: compared to that of non-reinforced mixtures, the performance of an asphaltic concrete, to which 3% pvc refuse has been added, is twice as satisfactory at 40 degrees C. Reinforced mixtures are generally more compact and less susceptible to tensile stresses. Although the cost of these mixtures is higher than that of conventional ones, the increase remains without reasonable bounds. /TRRL/
