随着我国公路和城市道路建设的进一步发展,特别是公路和城市道路养护的需要,以及环保意识的逐步增强,沥青混合料将逐步向集中拌和式的商品混凝土方向发展。如何评价沥青混合料的质量,特别是保证沥青混合料在满足设计要求上的均匀性就显得特别重要。文章针对沥青混合料VV、VMA、VFA等体积指标相对于原设计波动较大的现状,提出了采用沥青含量、VV、VMA3大指标评价沥青混合料均匀性的方法及相应的评价标准,并介绍了采用折线图和柱状图分析3大指标抽检结果的方法。
With the further development of roads and urban roads in our country, especially the needs of highway and urban road maintenance and the gradual increase of environmental awareness, the asphalt mixture will gradually develop toward centralized and mixed commercial concrete. How to evaluate the quality of asphalt mixture, especially to ensure that the asphalt mixture to meet the design requirements of uniformity is particularly important. In this paper, aiming at the present situation that the volume index of asphalt mixture VV, VMA and VFA fluctuates greatly compared with the original design, the method and the corresponding evaluation criteria for evaluating the uniformity of asphalt mixture using asphalt content, VV and VMA3 are put forward The use of line charts and histogram analysis of three major indicators of sampling results.
