METHOD TO COMPACT HOT ASPHALT-CONCRETE MIXTURE BY ROLLING WITH ROAD ROLLER

摘要

FIELD: construction.;SUBSTANCE: in the method of compaction of a hot asphalt-concrete mix by rolling with a road roller, which comprises four working elements that are combined in pairs as two balance trucks, mounted onto rotary platforms relative to the frame of the roller, compaction is carried out as a row of cycles. Each cycle in its first half consists in the fact that trucks are arranged at the edges of the compacted strip, and at the first stage they roll these edges, and subsequent stages are carried out by displacement of trucks towards each other with closure of the previously compacted division. The first half of the cycle is completed by rolling of the central part of the strip with tandem arrangement of balance trucks. The second half of the compaction cycle consists in reverse movement of trucks towards the edges of the strip. Full compaction of the strip is carried out in 2-3 cycles with preservation of the overlapping condition.;EFFECT: compaction of a strip is carried out simultaneously at its both edges by a single road roller, which increases efficiency of works.;2 cl, 3 dwg
