The document discusses factors that contribute to pavement deterioration over time, including traffic loading, climate conditions, and drainage issues. It also outlines different methods for evaluating pavement condition, such as measuring roughness, distress, and skid resistance. Preventative maintenance is highlighted as the most cost-effective approach for extending pavement life and performance. Proper design, construction, and material selection can help minimize early deterioration, while regular maintenance and rehabilitation are needed to avoid more costly repairs from deferred maintenance.
