Summary: This study aims to characterize RAP aggregate in sequence to obtain optimized proportions for strength. The experimental results showed that 40% washed RAP (WRAP) recycled aggregate with 10% zirconia silica fume (ZSF) as a replacement for cement outperforms dirty RAP (DRAP) aggregates in terms of strength. Therefore, Reclaimed Asphalt Concrete Pavements (RACP) are now seen as a potential long-term solution to the current environmental and economic crisis.

Summary: This study aims to develop sustainable bituminous paving mixes with the bulk utilization of waste materials such as reclaimed asphalt pavement (RAP) and recycled concrete aggregate (RCA), modified by waste polyethylene. The results showed that the modified RAP mixes exhibited significantly higher stability and rutting resistance compared to the traditional control mix. The addition of waste polyethylene reduced the susceptibility to moisture-induced damage. Overall, the RAP mixes prepared with different combinations of CSA or RCA with waste polyethylene can enhance the high and intermediate temperature performances of the RAP mix to a significant level.

Summary: Porous asphalt mixtures are becoming an attractive alternative for pavement surface layers due to their benefits in noise reduction, safety, and environmental aspects. However, their durability is lower than dense graded asphalt mixtures, leading to the need for the incorporation of different types of binders and additives to improve performance. The study found that polymer modified binders can enhance the ravelling resistance of the mixture without compromising functional performance.

Summary: The effects of adding fibers and Reclaimed Asphalt Pavement (RAP) on the low temperature performances of open graded and dense asphalt mixtures were investigated. Two types of fibers were used: aramid and poly-olefins fibers for reinforced porous asphalt and polyacrylonitrile fibers for conventional dense asphalt. The addition of fibers showed no significant effects on the low temperature strength but improved failure temperature and crack propagation resistance. The combination of fibers and RAP in mixtures designed with higher binder content can also be beneficial, suggesting further research on mix design is needed.

Summary: The properties of asphalt concrete mixtures were improved by introducing residual plastics as a substitute for virgin bitumen, which enhanced the sustainability of the mixtures. Experimental testing of different waste plastic materials and replacement percentages (15% and 25%) showed that introducing plastic materials increased the voids by approximately 5%. The mechanical performance of the experimental mixtures, particularly the resistance against plastic deformations, improved and even reached similar values to mixtures made with polymer-modified bitumen.

Summary: This communication discusses the latest experiences in slope and foundation drainage and runoff water management to enhance resilience in roadway infrastructures. Repair actions were taken to restore road safety and stability in Northern Spain after temporary rain and adverse weather conditions caused damage to road slopes. Heavy rains caused stone movements along the slopes as well as impressive waterfalls from karst caves, which were channeled into the Deva River through an innovative solution. The stabilization of slopes on the A-8 motorway was achieved through biological engineering. The effectiveness of these actions has been proven through a year of road operation, and the monitoring system used for full-scale tests is reliable for understanding force transmission mechanisms and future design purposes.

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: Incorporation techniques of phase change materials in cementitious composites have a significant influence on thermal properties. This study investigated the thermal behavior of low-temperature PCM when subjected to varying temperature change rates and pore confinement inside the porous network of lightweight aggregates. The results showed that ramp rates affect the nucleation and crystallization growth process during the phase transition, and the pore structure of the aggregates affects the supercooling phenomenon and confinement pressure of the PCM.

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.
