摘　　要：本文研究了稳定剂如羟乙基纤维素和氯化钙对乳化沥青性能的作用机理和效果。实验结果表明,适当添加稳定剂可以显著提高乳化沥青的储存稳定性和改善其干燥成膜过程。特别是在储存稳定性方面,稳定剂通过增加水相的黏度和电势差,有效减缓了沥青颗粒的沉降速度,提高了乳化沥青的整体稳定性。在干燥成膜过程中,稳定剂的加入有助于形成更均匀和持久的沥青膜,促进了乳化沥青与集料的良好黏附。This study adhesion performance of emulsified asphalt.It specifically examines the mechanisms and effects of stabilizers such as hydroxyethyl cellulose and calcium chloride on the performance of emulsified asphalt.The experimental results demonstrate that the appropriate addition of stabilizers significantly enhances the storage stability of emulsified asphalt and improves its film formation during drying.Notably,in terms of storage stability,stabilizers increase the viscosity of the water phase and the electrical potential difference,effectively slowing the settling rate of the asphalt particles and enhancing the overall stability of the emulsified asphalt.
