Book Description
This report describes a framework for the selection of pavement preservation treatments which can best utilize an available maintenance budget. it includes formulation of project-specific strategies, evaluation of funding requirements, and setting of priorities. the key component of the framework is an action plan which recommends preferred and fall-back strategies for all individual pavement management sections. the action plan documents the existing pavement condition, integrates all major pavement maintenance and rehabilitation efforts into a unified preservation plan, and coordinates pavement preservation functions of different offices within the ontario ministry of transportation. the optimum allocation of pavement investments is achieved by linear programming. sensitivity analyses evaluate the effect on the linear programming solution of using different optimization goals and different budget constraints. while the objective function used maximizes only technical benefits of pavement investments, it can be modified to include societal benefits as well.
