摘要
该文对国产岩沥青的路用价值展开研究,选择不同的基质沥青,分析岩沥青对沥青混合料的性能影响及岩沥青的最佳用量。试验结果表明,应用岩沥青可以显著提高沥青混合料的路用性能,岩沥青的最佳掺量为沥青质量的8%左右,同时岩沥青与基质沥青有一定的配伍性。
The article carries out the study of the road use value of the rock asphalt made in China. The article selects the different basic qualities of the asphalt and analyzes the influence of the rock asphalt on the performance of the asphalt mixture and the optimized dosage of the rock asphalt. The test result makes clearly that the application of the rock asphalt can obviously enhance the road use performance of the asphalt mixture. The optimized admixing dosage of rock asphalt is about 8% of the asphalt quality. At the same time,the rock asphalt and the basic quality asphalt have a certain matching performance。
