PROCESS FOR IMPROVING ADHESIVE ABILITY AND ELONGATION ABILITY OF ADDITIVE BITUMEN-BASED JOINT FILLER

摘要

Improvement of adhesion and elasticity of bituminous sealants for gap filling and repair of concrete, reinforced concrete and asphalt involves use of condensed linear polyamines and fatty acids that are used for partial replacement and improvement of bituminous sealants. The condensed prods. are added in required proportions to heated bituminous sealants under constant stirring. The latter is continued until the mix becomes homogeneous.
