Summary: This paper investigates the preparation of a high friction surface treatment (HFST) using magnetite (MT) aggregates instead of conventional calcined bauxite (CB) aggregates as microwave absorbers. The deicing properties by microwave heating and long-term skid resistance of HFST with different proportions of CB and MT aggregate were evaluated. The results showed that the electromagnetic characteristics of HFST were greatly enhanced by the addition of MT, leading to higher microwave heating and deicing efficiency. However, the long-term skid resistance of HFST was reduced by the addition of MT.

Summary: To improve the skid-resistance durability of asphalt pavements, this study introduced a differential-polishing principle based on blending various aggregates. Long-term simulated traffic polishing tests were performed on six types of ultra-thin friction courses (UTFC) surfaces. The results showed that differential-polishing effect effectively reduced the attenuation rate of skid resistance by maintaining a rough surface texture and a difference in wear resistance between aggregates.

Summary: Ultra-high performance concrete (UHPC) has excellent mechanical properties and durability, making it a promising material for bridge deck overlay or structural member repair. However, the large autogenous shrinkage of UHPC can hinder its application. This study develops a novel internal curing agent, calcined bauxite (CB) aggregate, to effectively reduce the autogenous shrinkage of UHPC and improve its mechanical properties. The results show that IC UHPC with CB aggregate exhibits smaller crack widths and delayed onset of cracking compared to normal UHPC, and the use of fibers further enhances its crack resistance. Normal UHPC overlay experiences more delamination and curling than IC UHPC overlay, and early-age drying has a detrimental effect on the UHPC overlay. Reinforcement in the UHPC layer proves to be effective in reducing shrinkage strain.

Summary: The primary goal of this article was to analyze the effect of texture on skid resistance. Measurements were made on three different groups of surfaces. The test results showed that the relationship between texture and skid resistance varied depending on the type of surface, with a relatively strong relationship found on reference surfaces but a shallow relationship found on aggregate and asphalt specimens. Further research with a larger sample size is recommended to explore different levels of texture.

Summary: This paper used a multi-variable accelerated abrasion machine to simulate the skid resistance attenuation of asphalt pavement and evaluated the skid resistance using British Pendulum Number. Three factors were considered during the abrasion process: aggregate types, nominal maximum aggregate size, and gradations. The results showed that the skid resistance of asphalt pavement decreased rapidly in the first stage, then at a relatively gentle rate in the second stage, and finally at the lowest rate in the third stage. The skid-resistance durability and stability were ranked based on the type of aggregate and the effect of aggregate parameters on skid resistance.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

Summary: Tailings dam break and leakage accidents pose a threat to the safety of people in mining areas and cause severe environmental pollution. This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.

Summary: This study investigates the fatigue behavior of concrete under different stress reversal conditions. The results indicate that stress reversal generally causes more severe damage and reduces the cycles to failure compared to tensile fatigue. Additionally, adding some level of compression contributes to the energy required for failure under stress reversal fatigue. Specimens with higher concentration of fractured aggregates achieve longer fatigue lives.

Summary: The susceptibility of building stones to fire and high temperature was investigated in this study by examining their physical and mechanical properties. The results show that both compressive and tensile properties of stones are affected by temperature changes. The tensile strength is particularly sensitive to temperature changes, requiring special attention to the components subjected to tensile stress in stone buildings. Principal component analysis was used to predict the mechanical properties of stones, providing a new method for calculating the residual mechanical properties after high temperature or fire.

Summary: This paper investigates the correlation between the friction coefficient and the surface roughness of concrete-to-concrete interfaces. Experimental tests were performed on specimens with different surface treatments, and the surface roughness parameters were analyzed and correlated with the shear strength and friction coefficient. The results showed that certain roughness parameters had a strong positive correlation with the friction coefficient, while others had little or no correlation. A novel combined roughness parameter with optimized correlation was proposed.
