- Abstract:
- Indentation test and bending test were adopted to investigate permanent deformation and deformation compliance of guss-asphalt for orthotropic steel deck plate. Factors of mastic Epüre content, fine to coarse aggregate proportion, temperature and loading pressure were investigated. It is pointed out that mastic Epüre content, temperature and loading pressure are the main factors influencing permanent deformation of guss-asphalt; fine to coarse aggregate proportion influences its maximum bending strain and crack energy at low temperature. The results indicate that there exists an optimum mastic Epüre content, and a critical operation temperature as well as a critical loading pressure for guss-asphalt in operation.
- 采用贯入试验与弯曲试验, 研究了沥青玛蹄脂含量、粗细集料的比例、试验温度与荷载压力等因素对浇注式沥青混凝土铺装的永久变形与变形追从性的影响. 结果表明: 沥青玛蹄脂含量、试验温度与荷载压力是影响浇注式沥青混凝土永久变形能力的主要因素, 而粗细集料的比例则影响混合料的低温极限弯曲应变与断裂应变能; 浇注式沥青混凝土中存在最佳沥青玛蹄脂含量, 而在实际运营过程中铺装存在临界温度与临界压力.
