维他连接剂橡胶沥青性能影响因素试验研究

研究了胶粉的种类、粒径、用量及拌和时间对橡胶沥青性能的影响。结果表明：两种胶粉（斜交胎与子午胎）对沥青性能的改善并无明显的差异；胶粉的粒径对性能有一定的影响；胶粉用量对沥青改性有显著作用。

Trial study of Influence Factor of Asphalt Rubber Adding TOR

This article examines the effect of crumb rubber in the different types,sizes,amounts and process time on the performances of modified asphalt.The result have been shown that they are not significantly different for improving the performance of asphalt with two types of crumb rubbers,while the size of crumb rubber has somewhat influence on the properties,and the quantity of finer crumb rubber affects greatly on modifying asphalt.
