排水降噪路面在养护工程中的应用

Application of Drainage and Noise Reduction Pavement in Maintenance Engineering

为研究开级配橡胶沥青混合料在排水降噪路面中的应用,解决公路工程中路面的抗滑、排水、降噪问题,论文对开级配橡胶沥青混合料的配合比优化设计进行研究,包括橡胶沥青、集料的选用,通过试验确定最大沥青用量和最小沥青用量,并得出结论:在最佳油石比为8.3%时,沥青混合料的马歇尔稳定度最大。

In order to study the application of open-graded rubber asphalt mixture in drainage and noise reduction pavement and solve the problems ofanti-slip,drainage and noise reduction ofpavement in highway engineering,this paper studies the optimal design ofthe mix ratio of open-graded rubber asphalt mixture,including the selection of rubber asphalt,aggregate,determining the maximum amount of asphalt and minimum amount of asphalt through the test.It is concluded that the Marshall stability of asphalt mixture is the highest when the optimum ratio ofoiltostoneis8.3%.
