分析 HVA 高黏剂的用量对 PAC-13 结构性能的影响

The effect of the amount of HVA adhesive on the structural properties of PAC-13 was analyzed

摘要:

由于排水沥青路面PAC-13雨天行车的安全性、舒适性，我国高速公路在建设中也得到了越来越多地推广应用，为了研究高黏剂HVA的用量对PAC-13排水沥青混合料结构性能的影响规律，结合经验法和试验法拟定了4组目标掺量，对应成型了HVA高黏剂掺量6%、10%、14%、18%空隙率为21.7%的PAC-13沥青混合料试件，开展了原材料和PAC-13 结构性能对比分析试验。试验结果显示：HVA掺量在范围约在10%，沥青的三大指标、动力黏度和混合料的析漏、飞散损失、TSR指标均符合要求，且经济合理。

Abstract:

Due to the safety and comfort of driving PAC-13 in rainy days, China's expressways have been more and more widely applied in the construction. In order to study the influence of the amount of high viscosity agent HVA on the structural performance of PAC-13 drained asphalt mixture, four groups of target dosage were proposed by combining the empirical method and the experimental method. The PAC-13 asphalt mixture specimens with HVA high adhesive content of 6%, 10%, 14% and 18% voids of 21.7% were formed, and the structural properties of raw materials and PAC-13 were compared and analyzed. The test results show that the content of HVA is about 10%, and the three indexes of asphalt, dynamic viscosity, leakage, flight loss and TSR of mixture meet the requirements and are economical and reasonable.
