目前 ,很多公路机构使用体积法控制Superpave混合料的生产 ,选用总混合料的空隙率( Va)和矿石集料的空隙率 ( VMA)作为质量控制参数。本篇论文分析了沥青粘结料的体积数据与集料级配间的关系。美国联邦公路总署 ( FHWA)将收集到的体积数据作为其示范计划 90—— Superpave沥青
At present, many road agencies use the volumetric method to control the production of Superpave mixes, using the voids (Va) of the total mix and the void fraction (VMA) of the ore aggregates as the quality control parameters. This paper analyzes the relationship between the volume data of asphalt binder and aggregate gradation. The United States Federal Highway Administration (FHWA) will collect the volume data as its demonstration plan 90 - Superpave bitumen
