Why Is This Important?
Portland's busy streets, also known as collectors and arterials, are where most of Portland's traffic travels, including transit and freight. It is important to keep these roads in fair or better condition to ensure safe access for transporting people and goods throughout Portland. Regarding pavement preservation, it is important to keep pavement in fair or better condition in order to keep repair costs affordable. Pavement typically deteriorates slowly during the first few years after it is installed. Then, it declines quickly after that, regardless of the street design or paving materials. It is much more costly to repair pavement in poor or very poor condition than it is to maintain pavement in good condition. Therefore, in order to maximize Portlanders' investment, our goal is to keep pavement in fair to better condition so we can deliver more affordable preservation solutions.
