According to the American Society of Civil Engineers, the backlog of repairs for existing highways is $420 billion. To help state transportation departments manage these backlogs and improve their...

Many strategies, including renewable energy production and carbon taxes, have been considered to reach climate targets. However, transportation agencies often overlook how their own pavement...

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...

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...
