用微表处来处理高速公路的车辙是一种经济、快速、有效的技术措施,但是填补车辙的微表处混合料要进行轮辙变形试验验证合格才能使用。微表处混合料中针片状对轮辙变形率影响较大,经过试验分析,并不是针片状越少越好,粗集料中具有一定量针片状时具有更好的抗车辙变形能力。 It is an economical, rapid and effective technical measure to deal with the rut of the expressway with the micro-surfacing, but the micro-surfacing admixture that fills the rut should be tested and approved for the deformation test of the deformity before it can be used. The micro-surfacing mixture in the needle flake on the rut deformation rate greater impact, after the test analysis, not the flake less the better, the coarse aggregate with a certain amount of needle flake has better anti-rutting deformation ability.
