ECA-10路面就地热再生技术研究

由于ECA-10路面低温稳定性相对较差，易开裂。尝试将就地热再生技术应用于ECA-10路面，提出就地热再生的同时掺入部分新料（加厚热再生）和原路面就地热再生（等厚热再生）两种方案，在室内对两种方案配合比设计进行研究。结果表明，两种方案的抗高温性能、抗水损害性能、抗飞散性能等均达到了SMA路面的技术要求，相比之下掺入新料更佳。

Research on Geothermal Regeneration Technology of ECA-10 Pavement

The low temperature stability of ECA-10 pavement is relatively poor, which makes it easy to crack.The in-situ thermal regeneration technology is applied to ECA-10 pavement.Two solutions are proposed: in-situ thermal regeneration with some new materials (thickened thermal regeneration) and in-situ thermal regeneration of the original pavement (equal-thickness thermal regeneration). The mix ratio design of the two schemes was studied indoors.The results shows that the high temperature resistance, water damage resistance, and scattering resistance of the two solutions can meet the technical requirements of SMA pavement, and the former is better.
