| Did you know?
The advent of asphalt came well before the birth of the paving machine. John MacAdam, a Scottish road engineer, developed the bituminous material in its earliest form in 1815. For road-paving applications, he would lay a compacted layer of aggregate and spray it with water, which dissolved the sands and salts, aiding in adhesion and binding. This material was named macadam in honor of its creator. Eventually, tar was used as a binding agent in lieu of water; the mixture became known as tar macadam, or tarmac. Roads were paved using tarmac through the beginning of the 1900s.
