Joint Filling Materials
BitumacCold applied bituminous mastic
BITUMAC is a modified bitumen mixture with elastomeric additives, special resins, organic solvents and inert materials. It is bitumen mastic which is applied in temperature of environment and has very good adhesion to porous as well as to smooth surfaces. BITUMAC absorbs the usual deformations of the joint, which occur due to temperature contractions and expansions as a result of its thermoplastic properties. The material has strong resistance to low concentration acid and base solvents and is not affected by subsoil salts. It is vulnerable to the use of petroleum solvents.
BJS (Bridge Joint System)
Hot applied bituminous mastic
BJS is a specially formulated hot applied polymer modified bitumen sealant. It can also act as a binder for asphaltic plug bridge joints. It has good adhesion to porous or smooth surfaces. The material remains elastic in temperatures varying from -20°C to 80°C. It has strong resistance to low concentration acid and base solvents. It is not affected by subsoil salts but is vulnerable to petroleum solvents.
