More than 90 percent of the road and highway network in the United States is paved with asphalt concrete. Maintenance and periodic rehabilitation require a continuous supply of aggregates and asphalt binder, both of which are becoming increasingly scarce and expensive. Recycling and reusing these resources can reduce costs and improve sustainability. The most...

Alkali—silica reaction (ASR) is a chemical distress mechanism that adversely affects the service life of concrete pavements. Key aspects of the reaction, such as the roles of calcium and aluminum on the structure of the gel and their correlation with swelling properties, have not yet been fully understood owing to the complex reaction mechanism. These...

Connected and automated vehicles (CAVs) will fundamentally change the way people and goods are transported from one place to another. Ensuring the safety of their operation and maintaining a safe transportation network will be paramount for the seamless integration of CAVs on public roads. Primary and secondary research was used in this study to develop an...

This literature review concerns microplastics from tyre and road wear caused by road traffic. As there is limited knowledge about microplastics in general, and microplastics from road traffic in particular, the Swedish Government commissioned the Swedish National Road and Transport Research Institute (VTI) to, during 2018-2020, develop and disseminate knowledge...
