Abstract

The purpose is to explore innovative applications of polyurethane elastomer in pavement maintenance, and broaden the technical approaches for pavement preventive maintenance. Using polyurethane elastomer as the base material, a novel rapid curing pavement maintenance seal with a low environmental impact was developed. The interlayer bonding performance of the seal under various construction conditions was analyzed. The surface functions of the seal, including skid resistance, abrasion resistance, and waterproof performance, were investigated. The structure and material composition of the polyurethane elastomer maintenance seal were optimized to suit different road conditions. The anti-glare ability of the polyurethane elastomer seal was evaluated. The results indicated that the polyurethane elastomer seal can form a relatively mature interlayer bonding performance within 1 h–3 h after preparation, with a bonding strength ranging from 1.2 MPa to 1.3 MPa. The abrasion value of the polyurethane elastomer seal was less than 200 mg/m². Among them, the seal using emery exhibited the best abrasion resistance, with an abrasion value of only 3–5 mg/m². Texture depth was 0.60–0.66 mm. British pendulum number was 70–82. The water permeability coefficient was 0, indicating excellent waterproof performance. The surface reflectance was 50 cd/m² to 150 cd/m², satisfying the basic requirements for anti-glare ability on pavements and posing no threat to driving safety.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
