Summary: This research examines the wearing effect of aeolian sand on asphalt pavements through experimental evaluation and testing methods. It proposes a wearing rate and prediction model for the pavement with sand particles. The results show that the presence of sand leads to pavement wearing, and the lubricating and wearing effects of sand on the pavement are predicted based on changes in texture and skid resistance.

Summary: Since the outbreak of COVID-19, the production and disposal of face masks have increased rapidly, posing a significant threat to the environment and public health. This study investigated the use of mask fiber (MF) in stone mastic asphalt (SMA) mixes to reduce waste and improve performance. Laboratory experiments were conducted on SMA specimens containing different percentages of MF and compared with control specimens. The results showed that the inclusion of MF improved the stability, resilient modulus, and resistance to moisture damage and binder drain-off.

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 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: 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: In order to avoid groove-related distress, airports are looking for an ungrooved runway surface option that performs similarly to dense graded asphalt. Stone mastic asphalt has been identified as the most viable solution, with laboratory testing showing that 14 mm mixtures perform better than 10 mm mixtures, especially in terms of surface macrotexture and deformation resistance.

Summary: This study used EMD method to analyze the asphalt pavement texture and its relationship with skid resistance. Different gradations and aggregates types have an impact on texture and skid resistance, while factors like tire state and speed rate also influence the correlation between texture parameters and skid resistance.

Summary: Graphene Tourmaline Composite Micropowder (GTCM) modified asphalt was prepared by ball milling. The high-temperature performance of the modified asphalt was evaluated under different temperatures and frequencies using dynamic shear rheological tests. The low-temperature rheological properties were analyzed using bending beam rheological tests, and the mechanism was analyzed using Fourier transform infrared spectroscopy (FTIR). The results showed that GTCM-modified asphalt had higher temperature sensitivity and anti-aging resistance compared to tourmaline-modified asphalt.

Summary: This study used a finite element model and ABAQUS software to investigate the friction performance between radial tires and asphalt pavement. The effects of pavement texture, tire parameters, and water film thickness on the tire-pavement contact force were analyzed through steady state rolling analysis and dynamic explicit analysis. The results provide theoretical references for safe driving.

Summary: Thermal cracking is a serious problem for airport bituminous pavements in cold regions. This study develops a design method for low-temperature performance-oriented airport bituminous mixtures. The study selects a design parameter, establishes a design procedure, and verifies the design method. The results show that the destructive tensile strain (DTS) of a low-temperature splitting test is sensitive to changes in bitumen content, making it a suitable design parameter for characterizing thermal cracking resistance.
