摘要
采用析漏和飞散试验结合的方式确定混合料的最佳沥青用量,对比研究了采用SBS改性沥青和高粘度改性沥青配制的OGFC(opengradedfrictioncourses,开级配沥青磨耗层)的路用性能。结果表明采用高粘度改性沥青配制的OGFC具有很好的路用性能,车辙动稳定度达5000次/mm以上。
The optimum asphalt content is decided through the experimental methods of dripage examination and relax examination. The performance of OGFC (open graded friction courses) prepared by SBS modified asphalt and high viscosity asphalt was studied. Results show that: OGFC prepared with high viscosity asphalt show good pavement performance and its dynamic stability reach above 5000 times/mm.
