LCA Research Brief: Roads: Smoothness Matters, But…
January 1, 2012

Interfacing modern pavement design tools such as MEPDG with Life Cycle Analysis (LCA) provides pavement engineers with an indispensable tool for a sustainable pavement design that is both...

LCA Research Brief: Accounting for Inflation in LCCA
July 1, 2011

This study examines historical data on real prices of construction materials, and finds that the assumption of constant real costs is seriously inconsistent with historical experience. Ignoring...

LCA Research Brief: When the Rubber Hits the Road
June 1, 2011

This research suggests that a mechanistic approach can close the uncertainty gap of Pavement Vehicle Interaction (PVI) in LCA of pavements. Implemented in an LCA environment, the derived...

LCA Research Brief: Adopting a Life-Cycle Perspective
April 1, 2011

The economic and environmental impacts of infrastructure should be evaluated using a life-cycle perspective. The coupling of two methodologies — lifecycle assessment (LCA) for environmental impact...

LCA Research Brief: Designing for Sustainable Pavements
March 1, 2011

The use of optimized design thicknesses helps reduce costs and CO2 emissions by minimizing the materials needed to construct a pavement. The economic and environmental benefits are significant and...
