Production of Bitumen Modified with Low-Molecular Organic Compounds from Petroleum Residues. 9. Stone Mastic Asphalt Using Formaldehyde Modified Tars

Abstract

The work is devoted to a completely new binder for asphalt-concrete mixtures, in particular, crushed stone-mastic mixtures. In the role of a binder, it is proposed to use raw materials for the production of bitumen − tars modified with a forming agent (catalyst and formalin). The paper proves the advantage of using tar modified with formalin, in comparison with standard oxidized bitumens, on the example of established physical and mechanical properties of bituminous binders and crushed-mastic asphalt concrete SMA-15.
