刚性基层抗裂材料开发与温度敏感性研究

摘要

为增加刚柔复合式路面耐久性，以高温软化点和低温延度为指标，开发刚性基层抗裂材料，测试了抗裂材料的基本性能，分析了材料组成、比例对抗裂材料的低温柔韧性和高温稳定性的影响，为抗裂材料的应用奠定基础。%In order to increase the durability of rigid soft composite pavement,taking the high softening point and low temperature ductility as the index,developed the rigid base anti-crack material,tested the basic performances of anti-crack materials,analyzed the influence of material com-position,ratio to the low temperature flexibility and high temperature stability of anti-crack material,laid foundation for the application of anti-crack materials.
