1、抗剥落剂的质量检验:随着抗剥落剂的普遍应用,各种产品涌向市场,其中也掺杂着很多不合格的产品,所以在选择时,一定要严格把好质量检测关。
1 quality inspection and anti stripping agent: with the widespread application of anti stripping agent, a variety of products into the market, which is also mixed with a lot of substandard products, so the choice, must be strict quality inspection.
2、抗剥落剂的试验方法:水煮法试验结果仅是评价沥青和粗集料粘附性的定性指标,残留稳定度指标也存在一定局限。所以,建议建设单位集中检验,对掺加抗剥落剂的沥青混合料提出冻融劈裂强度比要求,并得出相应残留稳定度指标,供施工单位校验,所以不能仅凭水煮法试验结果选择抗剥落剂。
2, the test method of anti stripping agent: boiling test results are only qualitative indicators to evaluate the adhesion of asphalt and coarse aggregate, residual stability index also has some limitations. Therefore, suggestions for the construction of centralized inspection unit, the freeze-thaw splitting strength ratio of adding anti stripping agent of asphalt mixture, and the corresponding residual stability index, check for the construction unit, so not only by water boiling test results of anti stripping agent.
3、抗剥落剂的最佳用量:要最大程度发挥抗剥落剂的作用,同时还应避免因高分子类抗剥落剂用量过大造成混合料性能的降低,应通过严格试验确定用量。 事实上,用量在0.3%以下时,水煮法试验结果也可以达到规范中对粘附性的要求,但是水稳性试验结果不一定满足符合规范规定,所以抗剥落剂的用量不应小于0.3%,但也不能过高。
The best dosage 3, anti stripping agent: to maximize the role of anti stripping agent, it should also avoid highmolecular antistripping agent caused by excessive mixing reducing the material properties, dosage should be determined through rigorous testing. In fact, the amount is below 0.3%, water boiling test results can also be requirements for adhesion to the specification, but the water stability test results do not necessarily meet the specification, so anti stripping agent should not be less than 0.3%, but not too high.
