大吨位振荡压路机与振动压路机压实效果对比分析

Analysis on Compaction Effect Comparison of Large-tonnage Oscillatory Roller and Vibratory Roller

针对振荡压路机在上、中、下面层施工中的应用情况,研究了大吨位振荡压路机对碾压不同铺层厚度沥青混合料的适应性,通过振荡压路机与同吨位振动压路机的对比试验,评估了两者的压实效果,为将振荡压实技术的应用扩展至中、下沥青面层的压实,以及进一步确定大吨位振荡压路机的优势应用领域提供了一定参考。

Aimed at the application of oscillatory roller on different surface courses of asphalt pavement,the adaptability of large-tonnage oscillatory roller compacting asphalt mixture with different thickness.The compaction effect was evaluated by comparing with vibratory roller of the same tonnage,which provides reference for application of oscillatory roller on middle and bottom course of asphalt pavement and helps to determine the advantageous application field for large-tonnage oscillatory roller.
