This webinar provides information about Canadian and international practices for managing weak pavement structures in Northern climates. Recommended best practices and an economic basis for making load management decisions on weak pavements will also be presented. Participants will learn about a decision support framework, which can be adapted to any road authority for use in making economically rational and defendable decisions with respect to restricting loads on these pavements.
