Roadtec is a part of Astec Industries, a corporation known as a world leader in asphalt technology. Founded in 1981, Roadtec began as a manufacturer of asphalt pavers. The 455 and 465 pavers were the first models built in Dalton, Georgia.
In 1986, the Barber-Greene Company was acquired to augment the product line. At that time, Barber-Greene was a major producer of pavers, milling machines, trenchers, crushers and asphalt plants. With the combined technology of Roadtec and the Barber-Greene Company, the paver line continued, along with the milling machines, and the concept of the material transfer vehicle was born. The first material transfer vehicle was the MTD 3500.
The Barber-Greene paver line was sold to Caterpillar in 1991 and Roadtec reorganized in Chattanooga, Tennessee to manufacture and market the entire line of road building equipment for Astec Industries. This included asphalt pavers and milling machines. It was around this time that the smaller, modern day Shuttle Buggy® material transfer vehicle evolved from the larger MTD 3500, rounding out the product line.
