GEM is an acronym for “Giant Earth Mover” or “Giant Excavating Machine”. [2] It was one of only two Bucyrus-Erie 1950-B shovels built (the other being The Silver Spade ) and one of two to use the knee-action crowd licensed from Marion Power Shovel in exchange for Marion's use of Bucyrus-Erie's cable crowd patent.
As highway construction moved away from rigid concrete construction, Blaw-Knox began making highway pavers for the new method of flexible asphalt paving . In 1931 Blaw-Knox introduced a form-riding finisher for asphalt paving. By 1932 they released the first self-propelled non-form riding finisher for the placement of stones and asphalt. [5]

The first production of concrete pavers in North America was in Canada, in 1973. Due to their success, paving stone manufacturing plants began to open throughout the United States working their way from east to west. [5] The first concrete pavers were shaped just like a brick, 4 by 8 inches (100 mm × 200 mm), and they were called Holland Stones.
The screed connects to the tractor portion of the paving machine via its tow arm. Paving material is transferred from the hopper at the front of the tractor to the screed, and augers spread it across the width of the screed. The material then flows out across the width of the screed at the desired depth. A screed operator stands on a platform ...
The machine mixed and placed asphalt in a single operation. This was first exhibited at the 1931 Road Show in St. Louis . Barber realized that the mixing and placing operations needed to be separated, and the mixing section became the line of Barber Greene asphalt plants and the placing section became the Barber Greene paver line.
A destoner is a machine that removes stones and clods from soil ridges and moves them to the furrow so that the ridges are free from stones. This also helps when harvesting in wet conditions as the harvester can drive on a row of stones which helps improve traction. They remove stone using a series of webs (between two and five webs).
