    Maintaining proper aggregate stockpiles Asphalt magazine

    Proper covering, grading, (and) paving under stockpiles, especially for fine aggregate, can help reduce dampness. “The importance of this must not be understated,” he said. All things being equal, “a one percent reduction in aggregate composite moisture will reduce the drying energy by 11 percent and increase plant production by 11
