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...

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...

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...

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...

Pavement Vehicle Interaction (PVI) can significantly contribute to the overall economic and environmental footprint of high traffic volume pavement systems. Past studies examining PVI have taken...

Any changes that occur in one place in an atmospheric system, due to factors such as wind speed, temperature, and surface albedo (the measure of the fraction of solar energy reflected by the Earth...

Damage to concrete slabs during freezing and thawing cycles represents a major challenge to pavement durability and resilience. This brief explores freeze-thaw cycles in concrete using models that...

Excess fuel consumption due to pavement-vehicle interaction (PVI) should be taken into consideration when assessing the environmental performance of a roadway network. Previous analyses have...

This brief explores time and location variations of albedo (the measurement of solar energy reflected from Earth’s surface back into space). The factors used to translate albedo to radiative...

The brief describes a new approach that transportation agencies could use to calculate the excess fuel consumption* of a highway network due to the material and structural properties, as well as...
