TL;DR: In this article, a comprehensive review on the engineering properties and environmental effects of recycled waste tire -sand/soil mixtures is presented, including compression and deformation behavior, shearing properties, dynamic features, and thermal/microstructural characteristics.

TL;DR: In this article, twelve methods to determine axial pile capacity directly based on cone penetration test (CPT) and piezocone penetration test data are presented, compared and evaluated, and two criteria are selected as bases of evaluation: the best fit line for Qp versus Qm and the arithmetic mean and standard deviation for the ratio Qp/Qm.

TL;DR: In this paper, the effect of the lignin content, moisture content, and curing time on the soil properties including compaction characteristics, thermal resistivity, unconfined compressive strength, and resilient modulus was investigated.

TL;DR: In this paper, the effect of moisture content, dry density, degree of saturation, particle size, and mineralogy composition on thermal resistivity of fine-grained soils was investigated.

TL;DR: In this paper, a field trial was carried out to verify the viability of using lignin stabilized silty soil as a highway subgrade course material, and the results revealed that as a stabilizer of the subgrade soil, lignins has negligible environmental influences and induces low construction costs.
