ABSTRACT:
The present invention is directed to an improved bridge joint and method for constructing a bridge joint in a channel or trench over an expansion gap in a bridge. The invention utilizes a Batron elastomer binder, which may be provided at room temperature and poured over aggregate chips in the channel, even in adverse weather conditions. The resulting mixture of Batron elastomer binder and aggregate withstands vehicular impact stress and provides adhesion and improved elasticity.
