DOI: 10.1038/s41598-024-72580-z

Abstract: China's operational highway subgrades exhibit a trend of diversifying types and an increasing number of defects, leading to more frequent urban road safety incidents. This paper starts from the non-destructive testing of urban road subgrade… read more here.

DOI: 10.1080/10298436.2017.1394101

Abstract: Abstract When designing pavements, there are three fundamental external design parameters to evaluate (1) the characteristics of the subgrade upon which the pavement is placed, (2) the applied loads and (3) the environment. This study… read more here.

DOI: 10.1139/cgj-2017-0594

Abstract: Rail tracks on peat subgrades can experience significant deflections, some of which have led to derailments. A potential ground stabilization strategy is to use screw piles to reduce rail displacements; however, limited research has been… read more here.
