Abstract:
1. An apparatus for treating a pavement surface with a plurality of layers in a single pass, comprising: (a) a chassis having a forward end and a rear end; (b) a plurality of rolling means spaced longitudinally along said chassis for supporting said chassis so it can roll along a particular direction of advance; (c) a powerplant for moving said chassis along said direction of advance; (d) a first storage tank mounted on said chassis for containing bituminous sealant; (e) a second storage tank mounted on said chassis for containing bituminous emulsion; (f) a main hopper mounted on said chassis for storing aggregate particles; (g) a first mechanism in flow communication with said first storage tank for applying a layer of bituminous sealant at a predetermined temperature and application rate on said pavement surface; (h) a second mechanism in flow communication with said second storage tank for applying a layer of bituminous emulsion at a predetermined temperature and application rate on said layer of bituminous sealant, wherein a thermal reaction occurs between said bituminous sealant and said bituminous emulsion so as to accelerate a material break and cure time for said layers; and (i) a third mechanism in flow communication with said main hopper for providing a layer of aggregate particles at a predetermined application rate on said layers of bituminous sealant and bituminous emulsion during said thermal reaction.
