Summary: The current calibration limits for British pendulum testers (BPT) can cause large discrepancies in measurements made by different BPT units, and stricter calibration limits may be difficult to achieve. To address this issue, a mechanistic harmonization procedure is proposed in this research, allowing measurements from different BPT units to be converted and compared on a common basis.

Summary: This research aims to improve the durability of skid resistance of asphalt pavement by investigating the morphology and characteristics of coarse aggregates. Through on-site testing and analysis, it was found that the skid resistance of asphalt pavement gradually decreases with service time, and the angularity and micro-texture of coarse aggregates are important factors affecting skid resistance. The correlation between micro-texture indexes and dynamic friction coefficient, as well as between roundness and skid resistance, is strong, indicating that micro-texture has a greater impact on skid resistance. In practical applications, the use of coarse gradation and high roughness or high anti-wear performance coarse aggregates can effectively slow down the attenuation of pavement skid resistance.

Summary: A multi-layer inductive healing layer (ML-IHL) based on the magnetic field distribution characteristics was designed to solve the gradient healing behaviors of conventional single-layer inductive healing layer (CSL-IHL). Two representative conductive metals, waste steel shaving and steel wool fibers, were used to prepare two kinds of ML-IHL. Results indicate that as the difference in the conductive metal contents between the two lays of the ML-IHL increases, the temperature gradient gradually decreases. In addition, it is recommended that the optimum content in the upper layer is 4% or 2%, and the optimum content in the lower layer is 8%. The inductive healing test of the optimal scheme shows that the healing effect of both ML-IHL layers has been significantly improved, and the healing rate difference between the two layers is all less than 2%.

Summary: This study investigated the effects of components' ratios and their interactions on the curing process and surface function of sand fog seal. Water can regulate fluidity and dispersibility, but prolongs the curing process. Modified sodium bentonite as filler shortens the curing time. The interaction of water and filler significantly affects bonding strength, with a recommended water-filler ratio of 1.5. The sand content should be controlled to less than 25%. A formulation design guideline for sand fog seal with recommended formulation of 21.8% water, 30% filler, and 25% sand was proposed based on desirability optimization methodology.

Summary: This paper adopts molecular dynamics simulation to study the nanoscale cracking mechanism in bitumen from four aspects: stress-displacement states, morphology evolution, energy contribution, and the relationship with chemical compositions. The simulation results reveal the stages of the cracking process and indicate that the cracking behavior is closely related to non-bond interaction, especially van der Waals interaction. Oxidative aging increases intermolecular bonding and reduces molecular mobility, resulting in higher tensile strength but lower ductility. The effects of temperature on the nano-cracking behavior are also presented.

Tests were conducted to evaluate the bond quality and durability of the chip seal samples prepared with both materials. Results showed that the hot rubber chip seal demonstrated significantly higher bond strength and better aggregate retention and cohesive strength than the asphalt emulsion chip seal. However, both treatments were deemed acceptable for pavement maintenance despite the weak bond between the materials and aggregate under cyclic load and freeze-thaw conditions.

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.
