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...

The CSHub has developed probabilistic price projections for paving materials that can fit within the framework of existing software tools for life-cycle cost analysis (LCCA), e.g. the Federal...

The use phase plays a significant role in a pavement’s life-cycle environmental impact. For both cases shown here it accounts for over 25% of the total global warming potential. However, its...

These results present an important step in identifying the role uncertainty plays as a function of context in LCCAs. This enables practitioners to understand the likely drivers of variation for a...

The new generation PVI model (Gen II) can account for the impact of temperature and vehicle speed in addition to that of other pavement structural and material properties on fuel consumption and...

Incorporating uncertainty in IRI predictions from MEPDG into LCA models improves the characterization of uncertainty in comparative LCAs, and increases the robustness of conclusions regarding the...
