A design method of a mixture to determine the proportions of mixing for a mixture of Asphalt Pavement.

摘要

Method of determination of the components and their relative proportions to obtain a mixture of Asphalt Pavement which produces a uniform area with a Predetermined percentage by volume of Air voids in a normal compaction.In a First operation was a compact Asphalt Cement mortar and Aggregates, by the method Marsahll, to determine the amount of Fine aggregate per unit volume of Mortar are computed subsequently Compacted; different amounts of Coarse and Fine Aggregates per unit Volume Of Fine Aggregate and asphalt Cement combinedThat Compares with the Compaction rate calculated empirically.After these operations, select a Point of balance, wherein one of the quantities computed is substantially equal to the index of Compaction, eventually goes on to determine the pre-set amount of Asphalt Cement and the combined mixture of Aggregates for Y to the Classification of Coarse and Fine Aggregates selected previously.After this study achieves a uniform Asphalt Pavement which is produced from natural Aggregates of variable Quality, and has a useful length ranges between 20 and 25 years.
