热阻抗滑表层开发及其高温性能评价
Development of thermal resistance friction course and evaluation of its high temperature performance
摘要
Abstract
To improve the high temperature stability of asphalt pavement in summer,thermal resistance materials with equal volume are used to replace aggregates of considerable particle size in asphalt mixture,in order to achieve active control of the temperature field of asphalt pavement.The influence of multi-grade refractory crushed stone amount on SMA-13 road performance and thermal resistance performance is studied by indoor simulated lighting experiments,and thermal resistance friction course(TRFC-13)is developed,and the high temperature anti rutting performance of TRFC-13 pavement is studied.The results show that when the lighting time is about 180 min,the surface temperature of the ordinary SMA-13 rutting board can reach 75 ℃,equivalent to an extremely unfavorable summer temperature of 41 ℃.It is recommended to simulate the lighting time for 180 min.In the single and two-grade aggregate replacement schemes,when using 4.75-9.50 mm refractory crushed stone to replace 60％of the ordinary aggregate with this particle size,the thermal resistance performance is the best,which can reduce the road surface temperature by about 7 ℃,and the road performance is reduced by no more than 12.5％,meeting the specification requirements.Compared with ordinary SMA-13,the dynamic stability of TRFC-13 pavement is increased by 23％,56％,114％and 255％at 38,39,40 and 41 ℃,respectively,but the fatigue life slightly decreases at 15 ℃.关键词
