Summary: This paper discusses the analysis of uniaxial tension-compression cyclic strain sweep test results for characterizing bituminous materials. The study shows that the damage mechanisms leading to failure vary with temperature, and the transition from slow to fast damage accumulation can be observed in the evolution plots of different mechanical variables. The Black diagram provides an excellent view of the damage and non-damage related mechanisms affecting the material's response to increasing loading amplitude. The stiffness modulus-phase angle curve is found to be a consistent indicator of the material's resistance to cumulative loading, showing sensitivity to the material's aging state and test temperature.

Summary: The linear amplitude sweep (LAS) test is useful for evaluating fatigue of asphalt binders, with good correlation found between binder and mixture fatigue performance. This study investigates the combined effects of strain and aging, proposing a new fatigue life model that accounts for both factors. The findings offer a simpler and reliable method for predicting fatigue life at new aging conditions, allowing for wider application in pavement engineering.

Summary: The study conducted time sweep tests with four oscillation amplitudes to investigate the energy dissipation behavior and rheological property evolution of asphalt binder under repeated shearing. It was found that both behaviors strongly depend on the oscillation amplitudes of fatigue loads and can be separated into two types. The variations in dissipated energy were related to different damage modes of asphalt binder, and criteria derived from dissipated energy were found not suitable for identifying the fatigue failure point of asphalt binder.

Summary: Long-term aging has a significant impact on the fatigue performance of asphalt pavements. However, the influence of aging on the fatigue resistance of asphalt binder is not well understood. This study investigates the effect of laboratory oxidative aging on the fatigue damage resistance and linear viscoelastic parameters of asphalt binder, and proposes different indicators of aging sensitivity. The results suggest that fatigue resistance increases with long-term aging at low strain levels, but eventually declines as aging level continues to increase.

Summary: This study introduces a new fatigue damage parameter denoted as the F parameter, which incorporates the effect of both peak shear stress and failure strain to better represent fatigue damage. Materials with lower F values are recommended for better fatigue resistance. The F parameter, along with fatigue diagrams, is considered a promising fatigue damage indicator in future works.

Summary: Dynamic modulus is a key parameter for performance prediction and pavement design of asphalt materials. The Indirect Tensile (IDT) test and the Uniaxial Compression (UC) test are commonly used to characterise the dynamic modulus of asphalt mixtures. This study compares the effect of these two test methods on the dynamic modulus and stress-strain state of asphalt mixtures. The results show that the mechanical properties obtained from both tests are similar, with some differences at lower and higher frequencies.

Summary: The linear amplitude sweep (LAS) test is a useful tool for evaluating the fatigue of asphalt binders. However, high cracking-resistant asphalt binders may not show significant damage in the strain amplitude sweep test. To address this issue, experiments were conducted by increasing the strain level or changing the control mode to stress control. The results showed that the fatigue life calculated based on the energy principle can well unify the results of the stress-controlled test and the strain-controlled test, and it is not dependent on the control mode of testing.

Summary: The basic assumption of traditional analytical models for asphalt pavements is that failure is caused by fatigue cracking of the bituminous layers. However, the effects of temperature, rest periods, and ageing of the bituminous materials question this assumption. Ageing leads to stiffening and transverse cracking of the asphalt layers, and thus the calculation of pavement life should consider these factors.

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.
