Asphalt has been around for centuries and its uses have been wide ranging. In ancient times it was used as an adhesive in its raw form to bind bricks and stones and also to waterproof boats. It was (and still is) used in roofing. Artists also tried to use asphalt in paintings until they realised that it never completely hardened which was a bit of a problem for creating enduring masterpieces. It wasn't until the 1800's that using asphalt combined with aggregates became popular leading to what we know today as probably the most hard wearing and durable road surfacing we now see everywhere.
