中文摘要:
      采用加速加载试验、冻融循环试验测试了导电超薄抗滑磨耗层在冻融、水压及重复荷载等因素作用下的导电和抗滑性能的长期耐久性.结果表明:导电超薄抗滑磨耗层初始电阻率为418×10-3Ω·m,3次冻融循环后变为415×10-3Ω·m,经冻融与100万轴次累积荷载耦合作用和50万轴次浸水加速加载后电阻率分别增大50%与25%;导电超薄抗滑磨耗层初始摩擦摆值为65~67BPN,经冻融与100万轴次累积荷载耦合作用和50万轴次浸水加速加载后摩擦摆值分别衰减100%与60%,即导电超薄抗滑磨耗层在导电和抗滑性能方面均具有良好的耐久性;在36V供电条件下,导电超薄抗滑磨耗层发热功率为4277W/m2(电极间距2m),可满足路面融冰雪需要.
英文摘要:
      Long term performance of skid resistance and conductivity of conductive ultra thin anti skidding wearing course(CUAWC) under freezing thawing cycles, soaking and repeated loading were evaluated by model mobile load simulator(MMLS3) and freezing thawing tests. Results show that the initial resistivity of the CUAWC is 418×10-3Ω·m, while the resistivity reduces to 415×10-3Ω·m after three freezing thawing cycles. The resistivity of the CUAWC increases by 50% after the coupling action of freezing thawing cycles and 1million cumulative load, and rises by 25% after 500 thousand cumulative soaking load. Moreover, the initial BPN value of the CUAWC is within 6567BPN, while BPN value decreases by 100% after the coupling action of freezing thawing cycles and 1million cumulative load, and reduces by 60% after 500 thousand cumulative soaking load. The test results indicate that CUAWC has good long term performance of skid resistance and conductivity. In addition, the heating power of CUAWC with 2m electrode gap can reach 4277W/m2 at 36V, which meets the need for melting ice and snow on road surface.
