灌浆路面容易发生开裂问题，影响路面服役寿命。为此，在灌浆料中添加水性环氧树脂（water-borne epoxy resin, WER）来改善灌浆复合混合料的性能。制备不同WER含量的灌浆料，并对其流动性能、凝结时间、力学强度和微观形貌进行表征。通过车辙试验、低温弯曲试验和浸水马歇尔试验对灌浆复合混合料的路用性能进行评价。结果表明，WER可以在水化产物表面形成膜结构，有利于提高灌浆料的柔韧性，但会延迟灌浆料的凝结时间。WER的添加会小幅度降低灌浆复合混合料的高温性能，但能提高灌浆复合混合料低温抗裂性能和水稳定性。特别地，7.5% WER使灌浆复合混合料的低温破坏应变提高了29.2%。

Grouting pavements are susceptible to cracking, which can significantly reduce their service life. For this reason, water-borne epoxy resin (WER) was added to the grouting materials to improve the performance of grouting asphalt mixtures. Grouting materials with different levels of WER were prepared and characterised for their flow properties, setting time, mechanical strength and micromorphology. The road performance of the grouting asphalt mixtures was evaluated through wheel tracking test, low-temperature bending test and water immersion Marshall test. The results show that, WER can form a membrane structure on the surface of hydration products, improving the flexibility of grouting materials. However, it also delays the setting time of grouting materials. The addition of WER slightly diminishes the high-temperature performance of grouting asphalt mixtures, but improves the low-temperature cracking resistance and water stability of grouting asphalt mixtures. In particular, 7.5% WER increases the low-temperature destructive strain of grouting asphalt mixtures by 29.2%.
