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.
