The work investigated the possibility of using construction waste such as asbestos-cement slate, glass, brick and concrete as aggregates in mixtures for the base layers of road pavement made using cold recycling technology. For this purpose, 17 mixture compositions were designed and studied - the control composition and 4 series of compositions, in which the milled fine-grained asphalt concrete was partially replaced by crushed asbestos-cement slate, glass, brick and concrete in an amount of 5-20 wt.%. All studied compositions contained 3% Portland cement and 3% water. The physical and mechanical indicators of mixtures and materials made using cold recycling technology with different construction waste contents were determined. The influence of the type and amount of the studied construction waste on the average density, water saturation and compressive strength after 7 days and 28 days of hardening at temperatures of 20℃ and 50℃ of road materials made using cold recycling technology was established.
