Abstract:
An oil-in-water emulsion comprising by weight based on the weight of the emulsion:(a) from 30 to 70 wt % of a bituminous binder having a penetration of from 40 to 150 mm/10 (ASTM D5), a softening point from 60 to 120Â° C. (ASTM D36) and a kinematic viscosity at 160Â° C. less than 250 mm2/s (ASTM D2170), the binder comprising from 88 to 99.5 wt % bitumen having a penetration of from 70 to 300 mm/10 and a softening point from 30 to 50Â° C., and from 0.5 to 12 wt % of an oxidised high density polyethylene wax having a melting point in the range from 100Â° C. to 150Â° C.; (b) from 0.01 to 5 wt % emulsifier; and (c) from 25 to 69.9 wt % water.
