Abstract: The pulling test and trabecular bending test were carried out for resin asphalt. Orthogonal design and pulling test methods were used to study the influence of factors such as asphalt content, curing agent content, resin content, curing time and curing temperature on the properties of resin asphalt. The optimum ratio, curing time and curing temperature were determined by low temperature trabecular bending test. Then toughening agent was added to improve the low temperature performance of resin asphalt, so as to realize its performance optimization. The research indicates that: the degree of influence on the resin asphalt pulling strength ranks as the content of curing agent>asphalt content>curing time> curing temperature. Furthermore, when curing time is 4 h, curing temperature is 120 ℃, curing agent content is 20%, asphalt content is 30% , content of toughening agent is 5% and the content of turpentine is 2%, it can guarantee its pulling strength as well as better low temperature performance.

摘要： 针对树脂沥青展开了拉拔试验和小梁弯曲试验。采用正交设计和拉拔试验方法对影响树脂沥青性能的沥青含量、固化剂含量、树脂含量、固化时 间和固化温度等因素进行了研究，并结合低温小梁弯曲试验确定出最佳的配比、固化时间和固化温度，再加入增韧剂提高树脂沥青的低温性能，从而实 现其性能优化。研究表明：对树脂沥青拉拔强度影响程度排名为固化剂用量>沥青用量>固化时间>固化温度，且当采用固化时间为4 h、固化温度为120 ℃ 、固化剂用量为20%、沥青用量为30%、增韧剂用量为5%、松节油用量为2%时，能在保证其拉拔强度的同时也有较好的低温性能。
