沥青混凝土路面混合料离析的成因与对策

沥青混合料离析是影响沥青路面质量及路面使用寿命的重要因素之一。高速公路沥青路面的早期损坏．如由水损害造成的网裂、坑洞、局部严重车辙、局部泛油、新铺沥青路面的构造深度不均等都与沥青混合料的离析有关。结合公路施工实践，分析沥青混合料离析的产生原因，提出了控制措施，以提高沥青路面施工质量。

Causes of Mixture Segregation of Asphalt Concrete Pavement and Countermeasures

The asphalt mixture segregation is one of the important factors affecting the quality and service life of asphalt pavement.The early damages of expressway asphalt pavement,such as net-shaped cracks caused by water damage,pot holes,local severe rutting,local bleeding,the discontinuity of surface texture depth,all are relevant to asphalt mixture segregation.Therefore,considering road construction practice,the causes of asphalt mixture segregation are analyzed,and control measures for improving the quality of asphalt pavement construction are proposed.
