LCCA Research Brief: Material-Specific Price Projections: Implementation
September 30, 2014

The CSHub has developed probabilistic price projections for paving materials that can fit within the framework of existing software tools for life-cycle cost analysis (LCCA), e.g. the Federal...

LCA Research Brief: Impact of Use Phase in Pavement Life Cycle Assessment: A Case Study of Alternative Designs in Different Contexts
April 11, 2014

The use phase plays a significant role in a pavement’s life-cycle environmental impact. For both cases shown here it accounts for over 25% of the total global warming potential. However, its...

LCCA of pavements: scenario analysis
LCCA Research Brief: LCCA of Pavements: Scenario Analysis
February 11, 2014

These results present an important step in identifying the role uncertainty plays as a function of context in LCCAs. This enables practitioners to understand the likely drivers of variation for a...

LCA Research Brief: PVI Mechanistic Model Gen II
December 23, 2013

The new generation PVI model (Gen II) can account for the impact of temperature and vehicle speed in addition to that of other pavement structural and material properties on fuel consumption and...

LCA Research Brief: Uncertainty in IRI Incorporated into LCA
June 1, 2013

Incorporating uncertainty in IRI predictions from MEPDG into LCA models improves the characterization of uncertainty in comparative LCAs, and increases the robustness of conclusions regarding the...

LCA Research Brief: Initial Cost Uncertainty in LCA
May 1, 2013

Using historical bid data to characterize uncertainty in initial costs for LCCAs will help improve the accuracy of probabilistic LCCAs. Some of the cost variation can be explained by understanding...

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...
