IMPROVEMENT OF THE UNIT FOR FILLING JOINTS, CRACKS OF ROAD COVERINGS.
Abstract
This article considers ways to improve the aggregate for pouring joints and cracks in asphalt concrete pavement, expansion joints in cement concrete pavement, reducing financial costs and minimizing human participation in repair work. Various reasons for the appearance of cracks on the road surface are listed. A review of the existing pavement seam fillers is made.
The main result of the study is the development of a trailed aggregate for a pavement joint filler, which can sequentially perform the following operations: filling cracks with asphalt concrete pavement bitumen, filling expansion joints with cement concrete pavement bitumen mastic, cleaning asphalt concrete pavement cracks from dirt, dust, moisture with compressed air.
