Maintaining proper aggregate stockpiles Asphalt

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 percent.”

Usage of solar aggregate stockpiles in the production

2016-9-5  Fig. 2 provides a schematic view of a solar aggregate stockpile in the HMA production process in a cyclic asphalt plant. From the overview given, it can be concluded that the main purpose of solar aggregate stockpile is to ensure the greatest possible thermal energy accumulation from solar radiation during the exposure period (the constructive peripheral elements), as well as to prevent the loss of accumulated heat in the period with no effect of solar radiation

2020-5-28  Paving the stockpile area totally eliminates losses from both of those causes. Because the front-end loader can scoop up material cleanly from a paved surface, there will be no buildup of aggregate. And, if a pile needs to be moved, it can be completely relocated without leaving any material on the ground. Furthermore,

stockpiling aggregate process -

Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.

Aggregate Segregation – Pavement Interactive

Aggregate Segregation. Based on several articles (Kennedy et. al., 1987 [2]; Brown and Brownfield, 1988 [3]; Williams et. al., 1996a [4] and 1996b [5]; Khedaywi and White, 1996 [6]; AASHTO, 1997 [7]) the commonly accepted qualitative definition of aggregate segregation is “the non-uniform distribution of coarse and fine aggregate components within the asphalt mixture.”
