To keep local roadways in good condition for the traveling public, Iowa county engineers monitor pavement conditions and analyze a wealth of pavement data to predict when and where maintenance will be needed. Now, a new tool developed through a research project for the Iowa Highway Research Board will help streamline this complex process.
Developed through extensive analysis of past pavement performance data from Iowa roadways, the Iowa Pavement Analysis Techniques (IPAT) tool will help engineers accurately and efficiently estimate the remaining service life (RSL) of individual pavement sections or roadway networks. Armed with reliable RSL estimates, engineers can plan and prioritize maintenance treatments and rehabilitation projects to make the best use of limited county funds. The IPAT tool will be implemented across the state in the coming months.
