ABSTRACT The varied damage faced by concrete in the pavement can be effectively alleviated adding polymer latex. However, their required high dosage and prices limit application. Hence, a new structure with gradient distribution of particles was designed. Furthermore, performance corresponding mechanism types contents on mechanical polymer‐modified mortar (PMM) were systematically evaluated. Compared to sample homogenous at same dosage, great enhancement compressive bond strength found for PMM structure. Besides, flexural also slightly increased. styrene‐acrylic (SA) ethylene‐vinyl acetate (EVA) latexes, styrene‐butadiene (SB) latex highest charge density shows lowest capability modifying PMM, which could caused its adsorption amount low ductility formed film. It further indicates that, compared tensile stress film, is more important determining PMM. To confirm obtained experimental results, finite element model mortars different structures established, modeling results match well measurements.

Abstract The mechanical properties of roadbed rehabilitation polyurethane grouting material (RhPU) under freeze–thaw cycles are the theoretical basis for evaluating its long‐term performance in cold regions, but currently not well understood. Freeze–thaw cycle tests were conducted on RhPU materials different densities using a rapid freezing method to investigate effects damage characteristics RhPU. experimental results indicate that frost is fatigue failure process from outside inside. During cycle, water‐filled cells experience compression due expansion and interconnected, forming more water seepage channels, accelerating internal Therefore, dynamic elastic modulus, longitudinal wave velocity, rigidity, compressive strength all decrease with an increase cycles. Moreover, at same cycles, lower density RhPU, greater loss rate strength. square velocity samples before after correlates density, better quantifies samples. Through scanning electron microscopy, microstructure was observed, revealing exhibits severe compared higher attributed larger cell diameter contact area between adjacent cells. This indicates poorer freeze resistance low‐density Highlights variations surface studied. correlation found. effect analyzed. microscale mechanism revealed.
