Description

Methods and conditions for obtaining carboxy-containing, peroxy-containing, phenol-formaldehyde and indene-cumarene oligomers (resins) with good adhesive properties have been developed. The kinetic regularities have been determined and effective activation energies of the mentioned processes have been calculated. The modification of petroleum bitumen by carboxy-containing, peroxy-containing, phenol-formaldehyde and indene-cumarene resins has been studied. The indene-cumarene resin (softening temperature 135 C) was found to be the most effective modifier. The yield of obtained bitumen-polymeric mixtures was 7.5 g per 100g of the initial bitumen. Their characteristics are: adhesion 100% (according to the method DSTU BV.2.7-81-98) and ductility of 36 cm (according to GOST 11505-75). The introduction of carboxy resin with peroxy groups into the polymeric mixture in the amount of 1 g per 100 g of the initial bitumen allows to obtain mixtures with 99% adhesion. Technical requirements for the sample of road bitumen aimed to be used as a component of asphalt-concrete mixtures or bitumen emulsions have been developed.
