Research Brief: How to Improve Pavement LCCA, A Case Study
June 26, 2017

Life cycle cost analysis (LCCA) frameworks are used by some transportation agencies for economic assessment, but there have been challenges implementing the approach, particularly in the...

Research Brief: Quantifying the impact of pavement reflectivity
March 13, 2017

The change in radiative energy balance, which is called radiative forcing (RF), reduces nearby air temperatures and impacts the surrounding building energy demand (BED) including heating and...

Research Brief: Minimizing Thermal Cracking in Concrete Pavements
November 30, 2016

Stresses resulting from thermal cycles within concrete pavements can cause expansion, contraction, bending, and flexing that can lead to fracture. This brief examines the risk of fracture of...

Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scalee
Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scale
August 31, 2016

Freeze-thaw damage is a potentially serious deterioration process that occurs in concrete structures in cold climates. While it is known that using certain deicing salts can aggravate the damage,...

Research Brief: Two-Phase Model of Pavement Fracture
June 2, 2016

CSHub researchers are working to understand pavement fracture at all levels, from the nano-scale up, so it is important to have a model that allows for the evaluation of cracks as they are forming...

Research Summary: Material Price Projections for Pavement Life Cycle Cost Analysis
April 6, 2016

For life cycle cost analyses (LCCAs) to provide the best information possible and lead to better decisions, the cost estimates must reflect, as accurately as possible, the most likely expenditures...

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...
