沥青混合料设计施工中的几个问题

Some Issues in Design and Construction of Hot Asphalt Mixture

在综合分析国内外沥青混合料领域最新成果的基础上 ,对Superpave集料级配限制区、压实沥青混合料毛体积测量方法、沥青混合料最大理论密度和沥青路面空隙率等问题进行了探讨。为这些问题的解决提供了思路或方向并提出了看法和建议。正确认识和解决这些问题对完善我国沥青混合料路面设计、施工体系具有重要的实际意义。

Based on the recent domestic and abroad research achievements in the domain of bituminous paving mixtures, the issues on restricted zone in superpave gradation, methods for measuring the bulk specific gravity of compacted HMA mixes , theorial maximum density of bituminous paving mixtures ,the degree of compaction in HMA pavements are discussed The ideas and ways of resolving these issues are provided and some views and suggestions are put forward in this paper The correct cognition and settlement of these issues may consummate the HMA design and construction systems in China
