| 摘 要： | 微表处技术是非常快速经济有效的高速公路车辙处理手段，作为一种高等级公路沥青路面预防性养护技术，其应用越来越广。微表处混合料含有专用改性乳化沥青及特殊级配集料，经过轮辙变形试验验证合格后，方可用于填补车辙。其针片状集料含量尤其对轮辙变形率影响较大，经过试验分析，表明针片状含量并不是越少越好，粗集料中含有一定量针片状集料时，微表处混合料具有较好的抗车辙变形能力。

| Abstract: | Micro - surfacing is a very good technology for highway pavement to fill rutting. But the Micro - surfacing mixes need to verify its good quality for filling rutting. With appropriate needle and flake chipping content can satisfied with its very good quality requeirment for resisting depth of rut deformation for preservation highway pavement. |
