Modified emulsified asphalt, cold-mixed and cold-laid wearing layer emulsified asphalt mixture and application of cold-mixed and cold-laid wearing layer emulsified asphalt mixture
The invention belongs to the field of road engineering, and particularly relates to modified emulsified asphalt, a cold-mixed and cold-laid wearing layer emulsified asphalt mixture and application of the cold-mixed and cold-laid wearing layer emulsified asphalt mixture. The modified emulsified asphalt contains matrix asphalt and water, and further contains 1-5% of a composite modifier on the basis of the total mass of the modified emulsified asphalt, wherein the composite modifier contains SBS and a polyether modifier in a mass ratio of (1-3): 1. By optimizing the formula of the modified emulsified asphalt, a net-shaped structure with relatively good water resistance can be formed in the emulsified asphalt, so that the viscosity and the water resistance can be synchronously improved. When the modified emulsified asphalt disclosed by the invention is applied to an emulsified asphalt mixture of a cold-mixed and cold-laid wearing layer, the noise, mechanical property and water resistance of a road surface can be improved at the same time, so that the modified emulsified asphalt is ensured to have good performance and durability in a use process.
本发明属于道路工程领域，具体涉及一种改性乳化沥青、冷拌冷铺磨耗层乳化沥青混合料及其应用。所述改性乳化沥青含有基质沥青和水，以改性乳化沥青的总质量为基准，其还含有1～5％的复合改性剂；其中，所述复合改性剂中含有质量比为1～3：1的SBS和聚醚改性剂。本发明通过优化改性乳化沥青的配方，能够在乳化沥青中形成具有较好耐水性能的网状结构，从而能够同步提升黏度及耐水性能。将本发明中的改性乳化沥青应用于冷拌冷铺磨耗层乳化沥青混合料中时，能够同时改善路面噪音、力学性能及耐水性能，从而确保其在使用过程中具有良好的性能和耐久性。
