PROCESS FOR PREPARING A BUMUMINOUS PAVING COMPOSITION, BETUMINOUS PAVING PROCESS AND BETUMINOUS PAVING COMPOSITION

摘要

bituminous paving composition and process for bituminous paving The invention features a bituminous composition, a process for the preparation of a bituminous paving composition and a process for bituminous paving having lower mixing, paving, and compacting temperatures than paving. heating mix while retaining sufficient performance characteristics of conventional hot mix paving. The paving process of the invention is composed of the steps of injecting a foamable solution composed of a lubricant into a heated asphalt binder to produce a heated foamed mixture; adding the heated foamed mixture to a suitable heated aggregate; further mixing the heated foam mixture and the heated aggregate to coat the heated aggregate with the heated foamed asphalt binder to form a heated paving material; supplying the heated paving material to a paving machine; applying the paving material heated by the paving machine to a surface to be paved; and compacting the applied paving material to form a paved surface.
