STRATA应力吸收层的级配特征与施工控制技术

Gradation Feature and Construction Control Technology of Strata Stress-Absorbed Layer

Strata应力吸收层是一种新型的延缓和防止反射裂缝的结构材料,在材料的要求、级配组成、施工控制等方面有很多特点,本项目依据湖北汉宜高速公路沥青混凝土路面加铺工程实践,对Strata的级配特征、性能验证、施工工艺及质量控制进行了研究与应用,取得了很好的效果。

As a new structure material for mitigating reflective cracking, Strata stress-absorbed layer has many characteristics in terms of material, gradation and construction. According to the overlay applyed to Han-Yi Expressway, the feature of gradation, performance verifying, construction technology and quality control of Strata stress-absorbed layer are studied.
