沥青混合料转运车对减轻沥青路面级配离析的作用

在沥青路面的施工过程中经常会出现离析现象,影响路面质量。为改善沥青路面的离析,国内外采用沥青混合料转运车对由运料汽车运来的、存在一定离析的混合料进行第2次拌和,然后再摊铺。本文采用多种方法对转运车在减轻沥青路面离析中的效果进行了评定,结果表明采用沥青混合料转运车可以有效地减轻沥青路面的离析。

The Effect of Asphalt Mixture Transfer Car on Asphalt Pavement Gradation Segregation

Segregation phenomena usually occurs during the construction of asphalt pavement,which will affect the quality of pavement.To prevent the segregation of asphalt pavement,asphalt mixture transfer car,which can mix the segregative mixture for the second time and transfer to spreading machine for spreading,is being adopted at home and abroad.The paper adopts some methods to assess the effect of transfer car on asphalt pavement segregation.The results show that the asphalt mixture transfer car could alleviate asphalt pavement segregation effectively.
