Built-in solar energy collectors. Traffic-predicting sensors. Space-age materials. Highways aren’t merely essential; they’re becoming cool.
Here, we look at some of the biggest innovations in asphalt, aggregates and highway building over the past few years. From ideas in the beta testing phase to those already implemented (and a few that failed), we explore the future of roadway construction, maintenance and durability — and where the aggregates industry fits into the mix.
