矿料级配对沥青路面低温抗裂性的影响

The Influence of Mineral Grading on Low Temperature Cracking Resistance

低温抗裂性是沥青路面的重要性质之一。良好的低温抗裂性可以保证路面的使用寿命以及路基的稳定性。沥青混合料的低温抗裂性有很多影响因素,主要阐述矿料级配对沥青混合料低温抗裂性的影响。通过对比相同沥青用量下,AC-5、AC-10、AC-13三种类型的沥青混合料低温抗裂性质的差异,确定矿料级配类型以及最大公称粒径对低温抗裂性的影响。

low temperature cracking resistance is the important property of asphalt pavement.Good low temperature cracking resistance can improve the working life of the pavement and the stability of subgrade.Asphalt mixture low temperature cracking resistance has a lot of influencing factors,this article mainly introduces the influence between mineral grading and low temperature cracking resistance.By compared with the differences of low temperature cracking resistance between AC-5、AC-10、AC-13 three types of asphalt mixture in the same bitumen content,it can determined the influence of mineral grading and nominal maximum size of aggregate to low temperature cracking resistance.
