Abstract
A binder for the production of a layer for road works or civil engineering comprises, with respect to the total weight of the binder: (a) 2 to 98% in weight of at least one purely natural or modified natural resin, of vegetable origin, having a softening point measured of 30 to 200° C.; (b) 98 to 2% in weight of at least one oil of vegetable origin having a viscosity at 25° C. of 50 mPa·s to 1000 Pa·s, (c) the binder having: (c1) either a penetrability at 25° C., of 20 to 300 1/10 mm and a softening point of 30 to 75° C., (c2) or a penetrability at 15° C., of 300 to 900 and a viscosity at 60° C., and (d) the binder being exempt of any natural or synthetic elastomer and of any thermoplastic polymer.
