Abstract: To investigate the compaction characteristics of a single-component polyurethane (PU) mixture with dense gradation, the effects of temperature, humidity, catalyst content, and standing time on the compaction energy index ...

Abstract: Pavement service and antiaging performance of single-component polyurethane-bonded porous mixtures (PPMs) were studied. The influence of the adhesive–aggregate ratio on PPM volumetric properties and pavement service ...
