“…Firstly, the type of improved material and the mixing ratio should be determined to meet the mechanical properties in the speci cation, which affects the silt-improved soil mechanics, improvement cost and improvement time. Soil solidi cation with lime is a common technique in soil subgrade engineering, which can improve the material's mechanical properties and bearing capacity (Mendes et al,2021). Lime is mainly used to dehydrate the soil and change the geotechnical properties, such as plastic limit, shear strength and soil compaction properties.…”

This study proposes to explore solid waste material (SWM) reuse with the riverway silt and sediment, and examines the impacts of chemical composition on the road construction through sensitivity analysis. Considering the characteristics of silt mixture, it is necessary to investigate the modi ed materials to improve the mechanical feasibility for subgrade lling. In this study, modi cation schemes for construction waste and garbage slag presented well mechanical properties and environmental bene ts in sensitivity analysis, especially for the high-water content silt modi ed by the garbage slag and lime mixture. The results indicate the lime-improved silt with medium water content is a cheap and highperformance material compared to the original silt. Moreover, modi ed silt demonstrated superior features in particle size, permeability and bearing capacity. Among six lime-improving schemes, the California bearer ratio (CBR 2.5 ) increased from 7.1 to 19.6, while the minimum CBR 2.5 was 2.45 times to the original silt. At last, this study proposes the engineering measures to improve the silt mixture subgrade to prevent heavy metals from polluting the water and soil environment. Further implications were also discussed.

Nylon waste bers (NWF) similar to new nylon bers possess high tensile strength and toughness, hence, they can be used as an eco-friendly discrete reinforcement in high-strength concrete (HSC). This study aimed to analyze the mechanical and permeability characteristics and life cycle impact of HSC with varying amounts of NWF and microsilica (MS). The results proved that NWF was highly bene cial to the tensile and exural strength of HSC. At the combined addition of 0.5% NWF and 7.5% MS, splitting-tensile and exural strength of HSC experienced net improvements of 49% and 55%, respectively. Lower doses of NWF were bene cial to the durability of HSC. However, 1% NWF was harmful to the durability of concrete. For the optimum mechanical performance of HSC, 0.5% NWF can be used with 7.5% MS. The use of MS also nulli ed the negative effect of the high volume of NWF on the penetration resistance of HSC.
