Condition Evaluation of Existing Pavements...

Pavement deteriorates with time, due to increases in loads and demand (loading cycles), variations in moisture within its base and subgrade that can damage its foundation, and exposure to the elements (freeze-thaw cycles or even de-icing chemical application). A proper diagnosis and preventive maintenance schedule-where smaller and less expensiverepairs are made at properly-timed intervals throughout the structure's life-significantly extends its life and reduces the costs associated with its ownership. (See earlier discussions on baseline condition assessments and QA verification of construction related to this topic.)
