New routes for roads: using recycled greenhouse films to modify bitumens

Gonzalez, O. / Munoz, M.E. / Santamaria, A.

Four recycled greenhouse films made of low density polyethylene and EVA copolymer, are mixed with 60-70 penetration grade bitumen. The goal is to improve the viscoelastic properties of bitumen used as a binder in road pavement, contributing to an environment improvement by reducing plastic waste. It is observed that a reasonable stability and a satisfactory upgrading face to rutting defect at high temperatures, can be achieved. The presence of a low amount of carbon black in two of the films does not alter the results. The content of film in bitumen/film blends is limited by stability problems (coalescence and creaming), as well as lack of flow capacity for pumping and mixing.
