摘要
以江西省乐温高速公路工程为例,用实验对比的方法对规范范围内不同级配曲线走向的混合料高温性能进行研究。结果表明:在规范范围内不同的级配曲线走向对混合料的高温性能影响很大,对于不同的原材料,最佳级配曲线走向应根据实验确定。
Taking the LeWen freeway engineering in Jiangxi province as an example, The paper studies the asphalt mixture＇s high temperature performance with different grading curve trend within specification confine by experiment and contrastive method. The result indicates that grading curve trend within specification confine greatly affect the mixture＇s high temperature performance, for a certain raw material, the optimal grading curve trend should be taken by experiment.
