Roadway joint-sealing apparatus which comprises a pair of elongated, substantially parallel, anchor pads adapted to be secured, respectively, to the upper surface of a roadway on opposite sides of a joint gap therein, said anchor pads being hard and wear-resistant;
- a flexible, resilient, sealing member extending longitudinally between said pads and integral therewith, said member being tubular in cross section;
- said pads and said sealing member being formed of elastomeric material and said pads being much harder than said sealing member;
- two sections of said apparatus being longitudinally aligned and abutted and a separate, short, flexible tubular member being internally secured in the adjoining ends of said tubular sealing members of said sections.
