Abstract :
Asphalt concrete, being a durable composite material, has found wide application in construction. Especially it is necessary to highlight its use as a road surface as a common and popular material. The process of compacting asphalt concrete by road rollers is a complex process, with its own specifics and disadvantages. The purpose of the research is to substantiate the availability of technologies for the continuous compaction of asphalt concrete pavement with a road roller. This article analyzes the drawbacks of current technology (reciprocating compaction with braking) and discusses possible solutions to problems by progressively compressing the mixture. The scheme of interaction between the roller of the roller with the compacted asphalt-concrete mixture is presented, the negative consequences of the reciprocating motion of the roller and sudden braking on the laid floor are described. The interrelationship of defects and their causes due to the fault of the roller or its driver were examined and analyzed. The expected effect from the introduction of the translational seal instead of the cyclic one is presented. In conclusion, the non-stop compaction of asphalt concrete pavement with a road roller is justified, and the advantages and disadvantages of various rolling technologies are described.
