Today, departments of transportation must solve the nation’s infrastructure crisis while facing ever-greater backlogs for repair. CSHub has found that implementing long-term planning and...

Healthy markets require robust competition. The paving materials market, though, possesses relatively little competition between industries and, as a result, has unnecessarily high unit costs. If...

The alkali-silica-reaction, a leading cause of deterioration in concrete, has been studied extensively—yet some of its mechanisms remain unclear....

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...

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...

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...
