离析导致沥青混合料的设计参数与实际参数发生变异,加速了沥青路面的损害,影响沥青路面的使用质量和服务水平,缩短了沥青路面的使用寿命。文章结合国内某条高速公路,在沥青路面施工中采用无核密度仪和激光纹理仪综合评价沥青路面施工离析,提供大样本的检测数据评价施工质量的均匀性,快速直观地发现离析范围和找到离析的原因,应用统计分析的数学工具定量地判断路面离析的程度和离析的范围。实践表明只有采用适当的无破损检测技术,才有可能获取足够多的样本数量对施工质量的过程与环节进行准确和定量的评定。
Segregation results in the variation of design parameters and actual parameters of asphalt mixture, accelerating the damage of asphalt pavement, affecting the service quality and service level of asphalt pavement and shortening the service life of asphalt pavement. Combined with a domestic highway, the asphalt pavement construction using nuclear densitometer and laser texture analyzer comprehensive evaluation of asphalt pavement construction segregation, providing large sample of the test data to evaluate the uniformity of construction quality, quickly and intuitively found the scope of segregation and find The reasons for segregation, the use of statistical analysis of mathematical tools to quantitatively determine the degree of pavement segregation and the scope of segregation. Practice shows that only with appropriate non-destructive testing techniques, it is possible to obtain a sufficient number of samples of the construction quality of the process and links for accurate and quantitative assessment.
