The True Value of Pavement Preservation

This article discusses the continuous and inevitable process of pavement deterioration, and highlights the importance of pavement preservation as a cost-effective solution. It explains that as the condition of pavement decreases, the rate of water flow increases, and the effort required to pump water also increases. The article also presents a cost comparison between seal, overlay, and reconstruct methods, and showcases a modeling analysis to emphasize the long-term costs of neglecting pavement maintenance.
