LCA Research Brief: PVI Mechanistic Model Refined
April 1, 2013

The refined PVI model can be used to obtain the deflection in any direction (including the direction perpendicular to the motion) and allows us also to study effect of tire shape and multi wheels...

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...

LCA Research Brief: Key Drivers of Uncertainty in Pavement LCA
November 1, 2012

This research presents a sensitivity analysis to quantify the level of contribution of different factors in the life cycle assessment of pavements under uncertainty. The results of this approach...

LCA Research Brief: Forecasting Prices with Limited Data
October 1, 2012

Characterizing the price behavior of inputs for concrete and asphalt is a major step towards identifying an appropriate price model in the absence of significant historical data. Current work is...

LCA Research Brief: Potential Roadway Network Savings and PVI
July 1, 2012

Analyses of the impact of PVI on vehicle fuel consumption for different roadway functional systems demonstrate the impact of pavement design and management on vehicle fuel consumption. Such...

LCA Research Brief: Comparative Pavement LCAs With Uncertainty
June 1, 2012

This research provides a probabilistic model for comparative life cycle environmental assessment of pavements in the presence of uncertainty and variation. Making use of this model (while...

LCA Research Brief: Network, Pavements and Fuel Consumption
April 1, 2012

Quantifying the impacts of pavement properties and management strategies on vehicle fuel consumption can provide guidance to pavement design and maintenance schedules while reducing the footprint...

LCA Research Brief: Modeling Uncertainty in LCCA
March 1, 2012

Interfacing this model with the recently developed MEPDG will allow decision makers to fully understand the probabilistic life-cycle cost of alternative designs for a given project. This will...

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...
