| 摘 要： | 采用高模量沥青混合料是解决沥青路面车辙病害的有效途径之一，而通过优选沥青胶结料、调整混合料级配和掺加外掺剂等技术均可以实现沥青混合料的高模量。依托实体工程，采用低标号沥青颗粒与70号道路沥青复配技术来改善沥青胶结料，并借鉴法国高模量沥青混合料设计思路进行高模量沥青混合料设计研究。研究表明，该混合料满足高模量沥青混合料技术要求并具有优良的路用性能。

| Abstract: | Adoption of high-modulus asphalt mixture is one of effective asphalt pavement, while high modulus of asphalt mixture can be realized asphalt cements, adjusting gradation of mixture and mixing additives, ways to solve rut diseases on by technologies of optimizing etc. Dependent on practical projects, this paper improves asphalt cements by means of combination technology of low-grade asphalt particles with No. 70 road asphalt, and draws lessons from design ideas of French high-modulus asphalt mixture to carry out design study on high-modulus asphalt mixture. The study shows that this mixture satisfies the technical requirements for high- modulus asphalt mixture and exhibits excellent road performance. |
