摘要
借鉴水泥混凝土坍落试验的方法，设计了一种冷补沥青混合料和易性评价的试验方法。采用国内外5种冷补料作为研究对象，通过试验分析，根据多种混合料试验后数据的平均值，以及试验操作者的主观难易程度。建议1/2塌落时间Th的值≥500s为宜，抹平时间Ts的值≤150s为宜，操作难易性主观评价值G≤3，且越小越好。
Abstract
In order to study construction workability evaluation methodof cold patch asphalt mixture, a test method for the constructionworkability evaluation of cold patch asphalt mixture was designed byreferring to the method of cement concrete slump test. Five kinds of coldpatch asphalt mixture are used as samples. The results of the analysisare based on the average value of the data and the degree of subjectivedifficulty of the experimental operator. The value of Th is not lessthan 500s. The value of Ts is not greater than 150s, and the subjectiveevaluation of G is not greater than 3, and smaller is better.
