Patent number: 8454739Abstract: The invention provides a bituminous composition, a process for preparing a bituminous paving composition and process for bituminous paving having lower mixing, paving, and compaction temperatures than for conventional hot-mix paving while retaining sufficient performance characteristics of conventional hot-mix paving. The inventive paving process comprises the steps of injecting a foamable solution comprising a lubricating substance into a heated, asphalt binder to provide a heated, foamed mixture; adding the heated, foamed mixture to a suitable, heated aggregate; further mixing the heated, foamed mixture and 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 heated paving material by the paving machine to a surface to be paved; and compacting the applied paving material to form a paved surface.Type: GrantFiled: March 14, 2006Date of Patent: June 4, 2013Assignee: Alm Holding Co.Inventor: Gerald H. Reinke
