The Influencing Factors of Volume Index on Mix Design of Asphalt Mixture

摘要：

Combining expressway reconstruction project number 20 and number 21 engineering entity of An Xin in HeNan province. At the target mix design of asphalt mixture in Mid-Surface of AC - 20, found in the process of testing specimen density of using a basket with netting on top of coarse aggregate and Marshall, the aggregate and Marshall can produce certain effect on its apparent density and bulk density when the test in condition of different dry conditions, this kind of influence will make the volume index VMA, W and VFA of mixture produce large deviation in mix design. The mix design was based on coarse aggregate and Marshall test under the condition of different dry apparent density and the bulk volume density, then Summarize the variation, and also summarized the influences of these changes for mixture volume index VMA, W and VFA . Through the laboratory test analysis and paving text road that good results have been achieved.
