- Abstract:
- The mix design method of asphalt rubber open-graded friction course(AR-OGFC)by the Marshall test and key technologies of AR-OGFC overlay are studied.Based on the draindown test, the stripping test and the Marshall test by different beating times, the asphalt content estimating method and Marshall beat criterion are studied.It is found that the asphalt content of AR-OGFC can be estimated by the formula of Arizona, and the proper Marshall test criterion for AR-OGFC is 50 beats on both sides.By analyzing the influence of gradation on OGFC performance, the gradation of AR-OGFC is recommended, and the amount of aggregate passing 4.75 mm should be minimized for AR-OGFC.Through investigation of AR-OGFC overlay projects, key technologies such as the treatment of underlying pavement and the selection of tack coat are advanced, and modified emulsified asphalt should be used in AR-OGFC overlay tack coat.
- 为研究橡胶沥青开级配混合料的马歇尔设计方法以及开级配混合料罩面应用的关键技术, 通过析漏试验、飞散试验和不同次数的马歇尔击实试验提出了橡胶沥青开级配混合料油石比预估方法和马歇尔击实标准, 表明油石比预估可采用亚利桑那州的预估公式, 马歇尔击实标准采用双面50次.通过对开级配混合料级配对性能影响的分析, 提出了橡胶沥青开级配混合料的级配范围, 发现橡胶沥青开级配混合料应尽量减少4.75 mm以下集料用量.通过总结橡胶沥青开级配罩面的工程经验, 提出了老路处治、粘层设计等方面的关键技术, 其中, 粘层材料宜采用改性乳化沥青.
