研究如何采用岩沥青、抗车辙剂等添加剂,根据实际需要和经济指标要求,均衡改善沥青混合料的各项性能。添加剂能使沥青混合料的高温性能显著提高,抗水损害能力有所改善,但岩沥青改性剂会略微降低低温性能,过量添加抗车辙剂会影响混合料的抗疲劳能力。结果表明,从实际出发,根据当地气候环境,通过联合应用,能最经济合理的确保各性能指标,能更好的适应,保证道路使用功能。 Study how to use rock asphalt, anti-rutting agents and other additives, according to actual needs and economic indicators, balanced improvement of the performance of asphalt mixture. Additives can significantly improve the high temperature performance of asphalt mixture, water resistance to damage improved, but rock asphalt modifier will slightly reduce the low temperature performance, excessive anti-rutting agent will affect the anti-fatigue ability of the mixture. The results show that from the reality, according to the local climate and environment, through the joint application, the most economical and reasonable guarantee of each performance index can be better adapted to ensure the road use function.
