Summary: An improved method, IMDBC, is proposed in this paper to estimate the fractal dimension of 3D pavement texture image based on grid displacement mechanism, showing better fitting accuracy compared to traditional DBC. By considering the contact characteristics between pavement surface and tire, the most suitable fractal texture surface for skid resistance is identified. The correlation coefficient between fractal dimension and friction reaches up to 0.6, indicating the potential of using fractal dimension indicator as a parameter to evaluate pavement surface skid resistance performance.

Summary: This study investigates the effects of nano-SiO2 and polypropylene fibers on the abrasion resistance of concrete. The results show that nano-SiO2 improves the abrasion resistance by densifying the pore structure and promoting the formation of hydration products, while excessive dosage of fibers negatively affects the pore structure and abrasion resistance. Additionally, the fractal dimension of the pore structure is closely related to the abrasion resistance strength of concrete.

Summary: The addition of silica fume and fly ash can improve the mechanical properties and abrasion resistance of concrete, while reducing the risks of drying shrinkage and cracking. Concrete mixtures with 5wt.% silica fume and 20wt.% fly ash show increased abrasion resistance and mechanical properties at various ages. Both fly ash and silica fume can decrease concrete porosity and increase the pore surface fractal dimensions (Ds), resulting in desired mechanical properties and abrasion resistance.

Summary: This paper investigated the mechanical and permeability performances of pervious concrete mixtures produced using different aggregates and fibers. The results showed that the pervious concrete specimens exhibited adequate mechanical performance, particularly with the inclusion of polypropylene fibers and steel fibers, which significantly improved the permeability performance and abrasion resistance. Moreover, using smaller-sized and more uniform aggregates generally increased the overall performance of the pervious concrete specimens.

Summary: This study investigates the strength, durability, and microstructural properties of Pervious Concrete (PC) made with Fly Ash (FA) and Silica Fume (SF) substitution. Nine different mixes of pervious concrete were cast to evaluate the study's objective. The influence of FA and SF on various properties of pervious concrete, such as workability, porosity, compressive strength, and acid resistance, were assessed. The study also utilized Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) for microstructural analysis. The results showed that substituting 10% of FA and SF significantly improved the strength and durability properties of PC, with a notable increase in compressive strength at different curing ages. The microstructural analysis revealed densified micrographs with even-layered C-S-H and C-A-S-H gel formation, contributing to the improved mechanical and durability characteristics of pervious concrete.

Summary: This study investigates the long-term skid resistance of epoxy asphalt and SBS-modified asphalt mixtures at room and high temperatures using indoor accelerated loading testing methodology. The results show that the decay rates of epoxy asphalt mixtures are lower than those of SBS-modified asphalt ones. Additionally, the fractal dimension of the epoxy asphalt mixture is larger and decays more slowly, and its section texture can be preserved to a greater extent during the loading process. Epoxy asphalt mixtures have better long-term skid resistance and greater retention of section texture than the SBS-modified asphalt ones.

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: In this study, different surface treatment methods were applied to improve the abrasion resistance of concrete. The results showed that surface treatments with polyurea waterproof adhesive and iron sheet significantly reduced the abrasion rate and exhibited low roughness after abrasion. Recommended thicknesses of polyurea waterproof adhesive and iron sheet surface treatments were suggested to enhance the resistance to debris flow abrasion of concrete protective structures.
