沥青混合料的离析是造成沥青路面局部损坏的根本原因之一,已经引起国际上的普遍重视。沥青混合料级配、摊铺设备以及施工过程都会对沥青混合料离析产生影响。本文主要探讨通过对RP952型摊铺机螺旋布料器的结构改进,来减轻沥青混合料摊铺施工过程中的离析问题。1.等距等径螺旋布料器的缺陷摊铺机后端与熨平板前部及其侧面挡板围成了一个沥青混合料槽。在沥青混合料摊铺过程中,先由刮板输送装置将沥青混合料输送到沥青混合料槽中部,再由螺旋布料器将沥青混合料均匀
Segregation of asphalt mixture is one of the fundamental causes of local damage to asphalt pavement, which has attracted widespread international attention. Asphalt mix gradation, paving equipment, and the construction process all affect the segregation of the asphalt mixture. In this paper, mainly through the RP952-type paver spiral distributor of structural improvements to reduce the asphalt pavement construction process of segregation. 1. Isometric equal-diameter spiral distributor defect Paver back and screed front and side baffle surrounded by a asphalt mixing tank. Asphalt paving process, the first scraper conveyor will be sent to the asphalt mixture asphalt mixing tank, and then by the spiral distributor of asphalt mixture evenly
