Design method of water-borne epoxy resin modified emulsified asphalt micro-surfacing mixture
The invention provides a design method of a water-borne epoxy resin modified emulsified asphalt micro-surfacing mixture. The design method comprises the following steps: (1) taking mineral aggregate; (2) taking the cation medium-slow breaking emulsified asphalt cementing material, wherein the solid content is greater than 60%; (3) preparing a water-borne epoxy resin system; (4) determining the pre-estimated asphalt-aggregate ratio of the used emulsified asphalt cementing material, simultaneously doping the water-borne epoxy resin and the curing agent into the emulsified asphalt, uniformly mixing, and determining the water consumption and the admixture cement consumption; (5) forming an asphalt-aggregate ratio-wet wheel abrasion value coordinate graph and an asphalt-aggregate ratio-structure depth coordinate graph, and then obtaining the optimal asphalt-aggregate ratio through a balance design formula; and (6) detecting whether the pavement performance of the micro-surfacing mixture under the optimal asphalt-aggregate ratio is qualified or not. The design method is easy to operate, the performance characteristics of the micro-surfacing mixture are comprehensively considered, and the method has good applicability to a waterborne epoxy emulsified asphalt micro-surfacing system.
本发明提供了一种水性环氧树脂改性乳化沥青微表处混合料设计方法，其包括以下步骤：(1)取矿质集料；(2)取阳离子中慢裂乳化沥青胶结料，固含量大于60％；(3)准备水性环氧树脂体系；(4)确定所用乳化沥青胶结料的预估油石比，将水性环氧树脂与固化剂同时掺入乳化沥青拌和均匀，确定用水量与外掺剂水泥用量；并以预估油石比为中值调整胶结料用量，制成不同油石比的湿轮磨耗试验标准试件，(5)形成油石比‑湿轮磨耗值和油石比‑构造深度坐标图，再通过平衡设计公式，得到最佳油石比；(6)检测最佳油石比下的微表处混合料的路用性能是否合格。设计方法操作简单，综合考虑微表处混合料性能特点，对于水性环氧乳化沥青微表处体系具有较好的适用性。
