Road – the construction laboratory conducts research to determine all the physical and mechanical properties of asphalt concrete mixtures in accordance with the requirements of the main national standards DSTU B V.2.7-119 “Asphalt concrete mixtures and asphalt concrete for road and airfield. Specifications» and DSTU B V.2.7-127 “Asphalt concrete mixes and crushed stone-mastic asphalt concrete. Specifications. The laboratory also tests aggregates for road construction (crushed stone, sand).
