The present invention pertains to carpet and carpet tile. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one non-chlorinated, non-polyvinyl butyral thermoplastic polymer or composition having a specific growth tension at 40 C and a specific residual stress at 25% strain. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred olefin block copolymer are ethylene based block interpolymers. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.
