Research Brief: The Impact of Traffic Jams on PVI Estimates
May 15, 2015

Excess fuel consumption due to pavement-vehicle interaction (PVI) should be taken into consideration when assessing the environmental performance of a roadway network. Previous analyses have...

Model depicting context dependent albedo effects.
Research Brief: A High-Level Analysis of Context-Dependent Albedo Effects
May 2, 2015

This brief explores time and location variations of albedo (the measurement of solar energy reflected from Earth’s surface back into space). The factors used to translate albedo to radiative...

LCA Research Brief: Mapping of Excess Fuel Consumption
December 5, 2014

The brief describes a new approach that transportation agencies could use to calculate the excess fuel consumption* of a highway network due to the material and structural properties, as well as...

Price forecasting for paving materials
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...
