To improve the engineering performance of high-liquid-limit soil, lignin, a by-product of the
papermaking industry, was used. First, the influence of lignin content and curing age on the …

To evaluate the long-term service performance of subgrade with high-liquid-limit soil
improved by lignin, a drying-wetting cycle test was carried out for the improved soil with 3 …

This study explores the possibility of using alkali lignin as a soil stabilizer as well as the
possibility of polymerizing alkali lignin to further improve its performance. The polymerization …

Lignin is an industrial by-product, stockpiles of which are rapidly increasing worldwide due
to growing demand. Highway subgrade construction has been identified as one of the viable …

The potential of a lignin-based by-product to stabilize silt was evaluated. The physical and
mechanical properties of silt in its natural state, as well as when treated with varying …

To mitigate the negative environmental effects of the overuse of conventional materials—
such as cement—in soil improvement, sustainable engineering techniques need to be …

Kaifeng Zhouqiao site is located in the traffic trunk line in Gulou District of Kaifeng City. The
dynamic load of urban traffic is large. In addition, the silt has poor stability of its particle …

Due to the increasing concerns on environmental pollution, fossil energy shortage, and
sustainable development, the recycling of industrial by-products had become a popular …

Lignin is a natural copolymer found in plants that is a major waste from bioenergy and paper
industries. In this study, comprehensive laboratory testing programs were carried out to …

This paper presents details of a study that deals with determination of engineering
properties and microstructural characteristics of a foundation soil (silt) sedimented in …
