钨酸锆掺量对沥青胶浆路用性能影响研究

THE EFFECT OF ZIRCONIUM TUNGSTATE DOSAGE ON ROAD PERFORMANCE OF ASPHALT MORTAR

为研究钨酸锆作为外掺剂在改善沥青胶浆低温路用性能效果,基于差示扫描量热(DSC)试验方法,对不同掺量钨酸锆的沥青胶浆的高、低温路用性能开展了试验对比分析。结果表明适宜掺量的钨酸锆,在保证高温性能的同时,对沥青胶浆的低温性能和降低胶浆的吸热率性能有明显的提高。工程应用中合理控制钨酸锆材料在沥青胶浆中的掺加比例是十分必要的。

In order to study the effect of zirconium tungstate as an external admixture in improving the low temperature road performance of asphalt mortar,the experimental analysis was carried out with the performance under the high and low temperature road performance of asphalt mortar with different contents of zirconium tungstate by the differential scanning calorimetry(DSC)test method.The results show that the suitable dosage of zirconium tungstate can significantly improve the low temperature performance and reduce the heat absorption rate of asphalt mortar while ensuring the high temperature performance.It is necessary to reasonably control the mixing ratio of zirconium tungstate material in asphalt mortar in engineering application.
