ABSTRACT: In the fall of 2015 the owners involved with the construction of Highway 104 in Antigonish Nova Scotia were faced with a dilemma. Sections of the project consisted of a subgrade that was built up during the winter months using backfill that was potentially frozen. The Nova Scotia Transportation and Infrastructure Renewal Department (NSTIR) chose to utilize a design which incorporated a multi-axial geogrid to overcome the poor subgrade and optimize the pavement such that the structural number for the section would meet or exceed the requirements for the highway and height restrictions would not be exceeded. This paper examines the process of design and presents the successful use of repetitive plate load testing to confirm that the foundation stiffness requirements were achieved on this project.
