为了提高普通乳化沥青混合料的路用性能，将乳化沥青与水性环氧树脂有机结合，得到一种新型复合材料——水性环氧乳化沥青。通过试验研究水性环氧树脂用量对混合料的力学强度、水稳定性以及温度稳定性的影响。结果表明：混合料的初期强度、后期强度以及高温稳定性随着水性环氧树脂用量的增加而提高，但其水稳定性和低温稳定性随着水性环氧树脂用量的增加先增大后减小，分别在水性环氧树脂用量为10%和15%时达到最佳提升效果。在实际工程应用中将水性环氧树脂用量控制在10%~15%之间。
In order to improve the road performance of ordinary emulsified asphalt mixture， a new kind of composite material， waterborne epoxy emulsified asphalt， was obtained by organically combining emulsified asphalt and waterborne epoxy resin. The effects of the amount of waterborne epoxy resin on the mechanical strength， water stability and temperature stability of the mixture were studied by experiments. The results showed that the initial strength， late strength and high temperature stability of the mixture increased with the increase of the amount of water-based epoxy resin， but the water stability and low temperature stability increased first and then decreased with the increase of the amount of water-based epoxy resin. The best improvement effect was achieved when the amount of water-based epoxy resin was 10%and 15%，respectively. In practical engineering application， the dosage of waterborne epoxy resin is controlled between 10%and 15%.
