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...

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...

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...

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

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...

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...

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...

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,...

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...

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...
