Title

RUBBER-MODIFIED BITUMENS

Pages

  303-309

Abstract

 BITUMEN in pure form is not suitable for modern roads and present traffic. This has forced engineers to modify BITUMEN to improve its PERFORMANCE during service life. Two routes are known for BITUMEN modification, that is chemical and physical modifications. Therefore, there are chemical and physical modifiers. Among physical modifiers, polymers (thermoplastics, RUBBERs and thermosets) are the most interesting ones. RUBBERs are very good BITUMEN modifiers. In this work non-vulcanized RUBBERs were incorporated into BITUMEN. The resulting blends showed better high and intermediate PERFORMANCE compared to the base BITUMEN. The improved properties are lower penetration and higher softening point. The low temperature properties such as Frass breaking point were not improved. New formulae for estimating BITUMEN’s PERFORMANCE using the results of conventional Frass and ring and ball tests were introduced. The morphology of the blends, depending on the rheological properties and compatibility of the RUBBER with BITUMEN, was different. Polybutadiene formed a continuous phase mixture in BITUMEN. This was observed due to the compatibility of this RUBBER with BITUMEN. Due to lesser compatibility between polymer and BITUMEN, SBRs and natural RUBBER formed polymeric inclusion dispersed in BITUMEN.
