Research Brief: Estimating The Impact Of Competition
February 1, 2016

In many contexts, the existence of either inter-industry or intra-industry competitive substitutes drives down prices.  Concrete and asphalt, the two primary paving materials, can be considered...

Research Brief: City geometry and Urban Heat Island
November 18, 2015

The urban heat island (UHI) effect is defined as a temperature difference between urban areas and their rural surroundings where the city temperature is higher. UHI is typically studied using...

Research Brief: Developing a Network-Level Pavement Management Model
November 17, 2015

Pavement management systems can serve as an excellent tool for federal and state transportation agencies searching for effective methods to maximize performance of pavement segments in the face of...

Research Brief: An Analysis of Concrete Joint Sawing
September 16, 2015

As concrete hardens, internal stresses can result in the formation of random, uncontrolled cracks in portland cement concrete (PCC) pavements. Joints are cut to release some of these early-age...

Research Brief: Analyzing Pavement-Vehicle Interaction through Bench-Top Experiments
August 26, 2015

Pavement Vehicle Interaction (PVI) can significantly contribute to the overall economic and environmental footprint of high traffic volume pavement systems. Past studies examining PVI have taken...

Research Brief: Quantifying Climate Impacts of Surface Albedo
July 15, 2015

Any changes that occur in one place in an atmospheric system, due to factors such as wind speed, temperature, and surface albedo (the measure of the fraction of solar energy reflected by the Earth...

Research Brief: Modeling Freeze-Thaw in Concrete
May 22, 2015

Damage to concrete slabs during freezing and thawing cycles represents a major challenge to pavement durability and resilience. This brief explores freeze-thaw cycles in concrete using models that...

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...

Mapping excess fuel consumption on Virginia highways
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...
