Summary: The study investigated the valorization of phosphogypsum and fly ash as road construction materials through lime stabilization. Statistical analysis showed that phosphogypsum addition decreased measured responses, while fly ash and lime caused them to increase. Fly ash addition notably increased compressive strengths at early ages, while at longer curing periods, the interaction with lime and the use of phosphogypsum as a catalyst improved fly ash reactivity.

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 evaluated the sorption and desorption capabilities of enzyme-induced calcite precipitation (EICP)-based treatment for tropical soils contaminated with divalent heavy metals. The results showed that EICP-treated soil retained the maximum quantity of cadmium (Cd) among all the heavy metals studied. The retention is attributed to the formation of CdCO3 and NiCO3 in the soil matrix, which exhibits very low values of solubility product even in the presence of aggressive chelants. The study establishes that EICP treatment is a prospective method for remediation of soils laced with heavy metal ions.

Summary: This study investigated the long-term and immediate effects of freeze-thaw cycles on the resilient modulus of two different expansive subgrades before and after lime-treatment. The results showed that freeze-thaw cycles led to a significant reduction in the resilient modulus, with the reduction mostly occurring after the first cycle and depending on the number of cycles. It is recommended to reduce the designed values of the resilient modulus when pavement subgrades may be subjected to freeze-thaw cycles.

Summary: The Kuttanad region in Kerala, India, is mainly composed of soft soil, which poses challenges for construction due to its low shear strength and water resistance. This study investigated the use of chitosan as a soil amendment to enhance the durability and erodibility characteristics of Kuttanad soft soil. The findings showed that adding 2% chitosan and curing for 90 days resulted in samples with unconfined compressive strength of over 1,000 kPa after five wetting-drying cycles. Additionally, samples with 2% and 4% chitosan exhibited the highest resistance to water erosion in drip erosion tests.

Summary: Bentonite is commonly used as the drilling fluid for cast-in-situ bored pile constructions. It has been observed that the formation of bentonite filter cake significantly reduces the shaft resistance capacity of piles in sedimentary bed rocks. However, its impact on crystalline metamorphic rocks is relatively insignificant. The lack of reliable experimental data has resulted in conservative pile designs being used, but recent studies conducted in Sri Lanka suggest that unnecessary conservatism can be avoided.

Summary: This study investigates the mechanical behaviors of hydraulic asphalt concrete (HAC) under combined compressive-shear stress at different temperatures and normal compressive stresses. The results show that the combination of normal compressive stress and temperature affects the peak shear stress and correlated shear strain. An increase in normal compressive stress leads to the emergence of horizontal cracks and an amplification of deformation at elevated temperatures. The peak shear stress progressively increases with an increase in normal compressive stress, but decreases with an increase in temperature. The study also establishes three modified compressive-shear failure criteria for HAC at different temperatures.
