Asphaltic plug joints for bridge (thorma joints)
ATAYA is an ENNIS FLINT-approved Applicator for the delivery and installation of the Thormajoint bridge joint range according to the Specification of Asphaltic plug joint.
ThormaJoint is a combination of an elastomer-modified bitumen binder known as BJ200 and a carefully selected single-size aggregate. The joint is constructed in layers, in-situ, and is a hot process.
BJ200 is manufactured by ENNIS FLINT and is a special blend of bitumen, polymers, fillers, and a surface-active agent formulated to combine good fluidity at process temperatures with low-temperature flexibility and ambient temperature flow resistance. It is delivered to site in bags in its solid-state, where it is heated in special boilers (double oil jacketed boiler) to its normal application temperature.
