东北季冻区透水性沥青混合料路用性能验证
|
摘要
目的为将透水性沥青混凝土路面应用于东北季冻区,对大油石比下的透水沥青混合料进行高温、低温、水稳定性能和渗水系数的研究.方法采用一种新的计算方法确定最佳沥青用量,以动抗压强度评价开级配混合料的高温性能,改进了冻融劈裂的试验条件,同时进行了小梁低温弯曲试验.结果大油石比5.8%时动抗压强度较最佳油石比5.3%下降了6%,抗水稳定性呈现逐步上升趋势,大油石比5.8%最大弯拉应变较最佳油石比5.3%提高了80%.结论大油石比下的透水沥青混合料的高温性能稍有下降,但低温性能和水稳定性能明显提高,更适合应用于东北季冻区.
In order to apply the permeable asphalt concrete pavement in the northeast seasonal frozen area,the performance of permeable asphalt mixture under the "large oil/rock ratio" was studied.A new calculation formula was used to determine the optimum asphalt dosage.Dynamic compressive strength was proposed to evaluate the high temperature performance of the open graded mixture.The test conditions of freeze-thaw splitting were improved,and the bending test of trabeculae beam was carried out under low temperature.The results show that the dynamic compressive strength of the 5.6% oil/rock ratio is lower than that of the 5.3% oil/rock ratio.The water-resistant stability shows a gradual upward trend.The maximum bending strain of the 5.8% oil/rock ratio is 80% higher than that of the 5.3% oil/rock ratio.The high temperature performance of the permeable asphalt mixture under the large oil/rock ratio is slightly decreased,but the low temperature performance and water stability can be significantly improved,which is suitable in the northeast seasonal frozen area.
