LCA Research Brief: Deterioration Induced Roughness in the US Network

February 1, 2013

Pavement material and structural design directly influence pavement performance and its deterioration rate. Pavements with slower deterioration rates require fewer maintenance activities to meet agency IRI guidelines and will have lower environmental impacts within the pavement lifecycle. Analysis of PVI roughness, its progression, and its impacts at a national level can guide design and policy for sustainability of the US roadway network. MORE
