摊铺机摊铺作业时,通过牵引臂拖曳熨平装置在沥青混合料摊铺层上前行,使熨平装置底部的熨平板与沥青混合料摊铺层表面形成一定仰角。该仰角直接影响成型路面的摊铺厚度、平整度及密实度。本文着重分析熨平板仰角的形成因素,以及熨平板仰角的影响因素。1.熨平板仰角形成因素熨平板在沥青混合料摊铺层上移动时,熨平板仰角形成因素主要包括熨平板受力状况和熨平板前部结构的影响等2个方面。
Paver paving operation, through the towing arm towing ironing device on the asphalt paving layer forward, so that the screed at the bottom of the ironing device and asphalt paving layer surface forming a certain elevation angle. The elevation angle directly affects the paving thickness, smoothness and compactness of the molded pavement. This paper focuses on analyzing the forming factors of the screed’s elevation angle and the influencing factors of the screed’s elevation angle. 1. Screed Elevation Formation Factors When the screed moves on the asphalt mixture paving layer, the forming factors of the screed elevation angle mainly include two aspects: the screed’s force condition and the screed front structure.
