Compression fatigue and self-heating effect of foamed polyurethane grouting materials for roadbed trenchless rehabilitation

Foamed polyurethane (PU) grouting materials are widely used for road trenchless rehabilitation. However, the temperature-rising under cyclic traffic loads affects fatigue resistance and ambient temperature. Therefore, in this work, the fatigue resistance and self-heating mechanism were revealed by I...
