Abstract:

Bituminous sealants used in the maintenance of roadways are installed hot and heated to 150°C-200°C during installation. High temperatures can degrade polymers in sealants, but there is no standard method to account for this possible degradation. In an attempt to find such a method, the aging of two sealants in large kettles during field applications was compared to that obtained in the laboratory by heating in a small kettle. The results indicate that 4h of small kettle aging (SKA) at the highest suggested sealant application temperature (HiSAT), or about 2h at HiSAT + 10°C, provided as much copolymer aging as that found in sealants sampled midway through installation.
