The Guide to Load Management for Weak Pavement Structures provides a synthesis of Canadian and international practices for managing weak pavement structures in northern climates. It includes a set of recommended best practices for managing these pavements through periods of freezing and thawing as well as for year-round pavement management. An economic basis for making load management decisions for weak pavement structures is presented. The Guide also contains a decision support framework, which can be adapted by any Canadian road authority and assists in making economically-rational and defensible decisions with respect to restricting loads on weak pavement structures.
