The conclusion is made about the inexpediency of further use of laboratory compaction by any pressure, as well as about the expediency of laboratory hardening by domestic (design of KADI "Doryastik") sector sealant, or foreign similar seals. The purpose of the work is to substantiate the method of laboratory compaction of asphalt concrete mixtures, which to the greatest extent in terms of density corresponds to the indicators obtained during industrial compaction. Research methods: devices and devices of laboratory compaction: pressing, stiffening, rotary shear-compression pressing. Materials accepted for research are asphalt concrete mixes and asphalt concrete types A, B, B on bitumens of various consistence. Product Description popup.authors Ilyin Yaroslav V Galkin Anlrey V.
