摘要
水泥路面上加铺沥青混合料时,土工布和粘层油的作用影响了摊铺机的附着性能,使机器滑转率增大,附着力减小,当摊铺作业阻力较大时,速度不稳定,严重影响了路面质量。应用理论分析与现场试验研究相结合的方法,对作业中摊铺机的附着力、摊铺阻力与附着性能等因素进行了分析;并对不同作业阻力时相匹配的滑转率进行研究。结果表明:为将摊铺宽度减小到设计值的2/3以内,可以采用梯形摊铺、使牵引阻力配置在额定滑转率较小的位置等措施以提高摊铺机的附着性能。
The bonding oil and geotextile affect the adhesion and the slip ratio of paver greatly. It decreases adhesion force, increases slip ratio, and the instable speed affects the quality of pavement seriously when the work force is higher. Through the locale test and theory analysis, this paper analyzes the influencing factors such as adhesive power, resistance force and adhesion performance, etc, studies the slip ratio matching diversity resistance force. The results indicate that when the paver breadth decreases to the two-thirds of design value, matching resistance force and rated slip ratio to minimum value and using trapeze paver can increase the adhesion force of paver. 6 tabs, 4 figs, 7 refs.
