ABSTRACT
Maintenance and rehabilitation (M&Amp;R) of pavements should ideally be conducted through the use of pavement management, which can ensure the optimum use of tax dollars through the selection and use of the most cost-effective design, construction, and rehabilitation strategy. Pavement management involves all activities regarding the planning, design, construction, maintenance, and rehabilitation of pavements. It is based on the pavement management system (PMS), which consists of a set of tools or methods that help pavement managers to plan for constructing and maintaining highway or airport pavements in a serviceable condition over a given period of time. Pavement information management systems (PIMS) or PMSs were mentioned in the 1986 American Association of State and Highway Transportation Officials (AASHTO) Design Guide. Portland cement concrete (PCC) overlays are increasingly being used as a rehabilitation technique for both existing PCC and hot mix asphalt pavements by potentially extending service life, increasing structural capacity, reducing maintenance requirements, and lowering life cycle costs.
