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