Abstract: In China, a large number of on-site investigations on the service conditions of asphalt pavements show that cracking has gradually become one of the most serious problems besides rutting. Part of the reason is that, in the ...

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: Polyether polyurethane concrete (PPC) is a new type of cold-mixed and cold-paved material. In this study, the strength evaluation mechanism of PPC was systematically investigated through test methods at different scales. ...

Abstract: Water stability resistance and internal void evolution behavior of the cold mix emulsified asphalt mixture (CMA) specimens at multiple freeze–thaw cycles were evaluated based on the tensile strength ratio from the indirect ...

Abstract: Nano-TiO2 combined with fogging technology can degrade automobile exhaust near road surfaces. Preparing nano-TiO2 in the form of three-dimensional ordered macroporous titanium dioxide (3DOM TiO2) can reduce the agglomeration ...

Abstract: This study examined a method to improve the water stability of macroporous polyurethane mixtures. Poor water stability of these mixtures has become an obstacle to their popularization and practical application. The water ...

Abstract: Stone mastic polyurethane concrete (SMPC) is a new pavement material that is mixed at room temperature and has excellent pavement performance. To accurately evaluate the moisture susceptibility of SMPC with varying ...

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 ...
