Summary: Driving speed, pavement type, surface characteristics, intermediate media, and tire properties are important factors that impact the frictional behavior between tire and pavement. A lack of equipment that can simulate the skid resistance behavior of high-speed vehicles based on real tire in the laboratory has been identified. To address this deficiency, High-speed Friction Testing (HSFT) equipment was developed, which utilizes real tire loading and provides reliable results for multi-factor coupling skid resistance tests. The results indicate that driving speed, water film thickness, and tire load have a negative correlation with skid resistance, with water film thickness having the greatest influence.

Summary: This study used the skid resistance analysis system to investigate the decay characteristics of pavement friction on contaminated roads and the impact of aeolian sand on skid resistance. The results reveal that aeolian sand fills in the macrotexture, weakening the road's skid resistance with adverse long-term effects. It is advised to clean the road surface regularly when the sand reaches 0.625 kg/m(2) to maintain its original skid resistance.

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: The laboratory tests were conducted to analyze the effects of particulate contaminants on the contact characteristics of tires and pavements on desert roads. Image analysis and generalized regression neural networks (GRNN) were used to reconstruct a three-dimensional model and predict the texture depth of asphalt pavements. The established skid resistance decay prediction models showed that sand quantity, temperature, and wearing cycles all influenced skid resistance, with sand having the greatest impact. The skid resistance model provided a reliable prediction of friction capacity and served as a reference for maintenance time determination in desert areas.

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 investigates the moisture and salt-erosion resistance of asphalt-calcined bauxite systems (ACBSs). The results show that the type of asphalt, aged asphalt, polymer modifiers, and grade of calcined bauxite all have an impact on the moisture and salt-erosion resistance. A lower grade of asphalt improves moisture resistance, while certain modifiers and nonammonia antistripping agents enhance salt-erosion resistance. The strength of the interface, influenced by the grade of calcined bauxite, plays a crucial role in preventing moisture and salt erosion.

Summary: An orthogonal test was designed to evaluate the skid resistance performance of asphalt pavement under cumulative wheel load and overload. Lab tests were conducted using the Tire pavement Dynamic Friction Analyzer (TDFA) to acquire real-time data of tire-pavement friction coefficient and pavement textures. The results showed that the pavement friction coefficients (COF) increased first and then decreased, while Mean Profile Depth (MPD) values fluctuated significantly. There was also a poor correlation between COF and MPD values. Additionally, the deterioration rate of pavement dynamic friction coefficient was faster and the final value was lower when heavy traffic was applied in the early stage compared to the middle and late stage of wear. The designed orthogonal test demonstrated the significant impact of total traffic volume, occurrence interval, and duration of heavy traffic on the COF value.

Summary: Compared with traditional PCC, PC has significantly higher skid resistance under dry, wet and icy surface conditions. Treatments with anti- and de-icing agents can improve the friction ability of iced PC to the allowable BPN level. Field testing showed that PC installations generally have similar or slightly higher BPN values than adjacent PCC slabs, indicating potential for higher skid resistance in PC.

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.
