Abstract: The purpose of this work is to obtain from VKOFAP (secondary VAT residue of phenol-acetone production) an organic binder that meets regulatory requirements. VCOFAP was modified with a complex additive represented by polyvinyl chloride screening and distillation residues of phthalic anhydride distillation. Secondary viscoplastic HCOFAP is formed from primary HCOFAP during the joint production of phenol and acetone by the cumene synthesis method and contains up to 50 % of resinous and condensation products, dimers and volatile components: a-methylstyrene, phenol, acetophenone. The indicators of physical and mechanical properties of concrete prepared on a complex organic binder exceed those of hot tar concrete. They are characterized by higher compressive strength at 50 °C and a wider temperature range of performance in the viscoelastic state; lower temperature sensitivity of mechanical properties. Consequently, coatings built from concrete mixes based on a complex organic binder will be durable under the action of transport loads.
Keywords: road asphalt concrete, viscoplastic secondary cubic residue of phenolic-acetone production, polyvinyl chloride, cubic residues of distillation of phthalic anhydride.
