Topic Summary: Context Dependent Pavement Life Cycle Analysis
July 17, 2019

While it is commonly believed that the environmental footprint of pavements derives only from their construction and materials, a large proportion of that footprint actually comes from their use...

Research Brief: Modeling the Freeze-Thaw Damage Mechanism in Cement
January 30, 2019

In this research brief we propose a new way to understand the cause of freeze-thaw damage in cement. While conventional thinking attributes the damage to pressure generated by expansion of water...

Research Brief: The Influence of Incorporating Uncertainties and Treatment Path Dependence in Performance-based Planning Analyses
November 9, 2018

With low funding and high backlogs for repair, state agencies must effectively allocate budgets for the maintenance, rehabilitation and reconstruction of highways. To assist this mission, CSHub...

Research Brief: Climate Change Mitigation Potential of Pavement Albedo
January 16, 2018

Albedo is the measure of how much solar energy is reflected by the Earth’s surface. Low albedo, or darker color, surfaces absorb more heat and reflect less shortwave radiation than high albedo, or...

Research Brief: The influence of analysis period on pavement network performance
November 15, 2017

Existing pavement management systems mainly explain and evaluate current conditions. Performance-based planning combines data about current conditions with models that estimate likely future...

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...
