论 D--II 改性剂在高速公路中的应用论 D--II 改性剂在高速公路中的应用 摘要:普通沥青砼存在低温易开裂、高温易软化的弊端,若在沥青混合料只需入加 0
5—3%的新研制的 HD 系列抗车辙添加剂,就能明显提高沥青混合料的抗高温稳定性,同时还可改善其抗水损坏和抗低温开裂性能等
本文介绍了 D-II 改性剂的性能、改性机理
并通过在太长高速公路路面施工中的试验应用实例论述了其对抗车辙效果的提高

5 - just 3% of new developed the HD series of anti-rutting additive can obviously improve the resistance to high temperature stability of asphalt mixture, and can also improve its resistance to water damage and low temperature cracking resistance, etc
D - II performance of modified agents were introduced in this paper, the modification mechanism
And through the experimental application in lo
