What mechanical and durability parameters are typically specified in rubberised bitumen emulsion documentation?
Rubberised emulsion documents usually focus on residue performance rather than the emulsion itself. Common parameters include elastic recovery, crack bridging or flexibility at low temperature, softening point or high temperature deformation resistance, and adhesion or peel strength on typical substrates. Durability sections may include water resistance, resistance to aging or heat stability, and performance after wet dry cycles. For road maintenance, abrasion resistance and chip retention related indicators may appear. Always verify test methods, acceptance limits, and whether values are for residue after evaporation or for the emulsion as supplied.
