HIGHWAY IMPACT STUDY OF THE EFFICIENCY OF COATING AND BASE COMPACTION WITH THREE-ROLLER TANDEM COMPACTORS
We present a highway impact study for increasing efficiency of compaction of coatings and bases through the use of three-roller tandem compactors. Calculations have been performed showing the possibility of a sequential increase in the vertical loading of the rollers of a compactor as the strength of the compacted surface increases over a wide range (up to 1.1 of the weight of a serial compactor) due to the use of an additional controlled section. The possibility of reducing the number of passes of the compactor by increasing the number of its rollers has been established. A technical and economic calculation was carried out confirming the feasibility of using such road compactors made on the basis of serial two- roller tandem compactors, which is due to an increase in productivity by 1,27…1,5 times.
