通过分析现行微表处配合比设计过程中存在的不足,文章提出增加肯塔堡飞散实验以确定沥青的最小用量。提出以曲线拐点来作为微表处混合料配合比设计的最小沥青用量,也可把此值作为最佳沥青用量值。
By analyzing the existing deficiencies in the design of mixture ratio of micro-surfacing, the paper proposes to add Kentucky fly-away experiment to determine the minimum dosage of asphalt. The inflection point of the curve is proposed as the minimum asphalt content designed by the mixture mix of the micro-surfacing station, which can also be taken as the optimal asphalt dosage value.
