Abstract
The use of flake glass in road pavement and repair is disclosed. In particular, we disclose improvements in the formulations of asphalt aggregate wear surfaces, substrate layers and interface layers between the substrate and wear surfaces. In one embodiment we also employ an unsaturated monomer or an unsaturated elastomer.
Claims14
An upper surface wear course for a road pavement consisting essentially of (a) at least 90% by weight of a stone aggregate and (b) the balance of an organic matrix consisting essentially of (1) an asphalt and (2) flake glass particles, said flake glass particles being interspersed with the asphalt and uniformly distributed therein and the stone aggregate being dispersed in a continuous phase of the organic matrix.
An asphalt road paving composition consisting essentially of (a) stone aggregate and (b) a uniformly dispersed organic matrix of (1) an asphalt, (2) flake glass, (3) an unsaturated elastomer and (4) a vinyl-substituted aromatic compound.
A bituminous composition for filling cracks in road pavements consisting essentially of (1) asphalt, (2) 0.5 to 10% flake glass, (3) a vinyl aromatic monomer and (4) an unsaturated elastomer.
