摘　　要：为实现实验室中对橡胶沥青与石料间粘结力的快速测试,设计了一种基于螺旋传动的简易装置,介绍其工作原理,并做了可行性分析及相关试验。试验结果表明:特定目数下,粘结力最大值随掺量增加而增大;掺量为15%时,粘结力最大值随橡胶粉目数增加而增大;目数和掺量适当时,橡胶沥青粘附性优于SBS改性沥青和基质沥青。In order to test the bonding force between rubber asphalt and aggregates, a simple tester based on helical gearing hypoid was designed; the working principle was introduced; the feasibility was analyzed and some relevant experiments were conducted. The results show that： when the mesh of rubber powder is specified, the maximum bonding force rises along with the increasing of rubber amount;when the mixing amount is 15 %, the maximum bonding force rises along with the increasing of mesh of rubber powder;when the mesh and mixing amount are both proper, rubber asphalt＇s adhesion is better than SBS modified asphalt and base asphalt.
