浅议沥青与集料的粘附性

结合力学理论、化学反应理论、分子定向理论、静电理论,分析了沥青与集料的粘附机理,探讨了沥青、集料、水及荷载等因素对沥青与集料之间粘附性的影响,最后比较了水煮法、水浸法、光电比色法、净吸附法等粘附性试验方法的优劣,就我国目前状况,仍推荐使用水煮法或水浸法。

Simple Talking about Adhesive of Asphalt to Aggregate

In the light of mechanical theory,chemical reaction theory,molecular orientation theory and electrostatic theory,the paper analyses the adhesive mechanism of asphalt to aggregate,makes an approach to influence of the factors as asphalt,aggregate,water and load on the adhesive of asphalt to aggregate and lastly contrasts each to other the adhesive testing methods like the boiling method,emmersion method,photoelectric colorimetric method and net absorption method etc.Based on current state in our country,there is still recommended the boiling method or the immersion method.
