These joints are formed when a new lane of hot mix asphalt pavement is placed adjacent to a previously placed lane. An improperly constructed longitudinal joint forms the weakest link threatening the whole pavement system. This article discusses the various techniques used to […]

Though pavements have been viewed as detrimental to the fight against climate change and urban heat islands (UHI), the evolution of reflective pavements will change this perception for good. The implementation of reflective pavements, also known as cool pavements, can help prevent extreme […]
