Asphalt slurry must be warm to efficiently pump through an asphalt plant operation. Many pieces make up the network to process quality asphalt, but a high-efficiency hot oil heater is at the center of that system.

In order to keep the asphalt slurry pliable, the hot oil flows through the tank heating coils in a serpentine fashion. Tank coils are often designed in a star layout for even heat distribution. Depending on process conditions, we may recommend bare or helically wound tank coils made of either carbon or 316L stainless steel.

As the asphalt slurry makes its way to be pumped out for transport, the long travel may reduce its temperature. On its last pass, the asphalt will pass through the shell side of the inline shell and tube heat exchanger while the hot oil passes through the bundle. The asphalt is now ready for pumping and transport.

The majority of steam rollers are outwardly similar to traction engines as many traction engine manufacturers later produced rollers based on their existing designs, and the patents owned by certain roller manufacturers tended to influence the general arrangements used by others. The key difference between the two vehicles is that on a roller the main roll replaces the front wheels and axle that would be fitted to a traction engine, and the driving wheels are smooth-tired.

Before about 1850, the word steamroller meant a fixed machine for rolling and curving steel plates for boilers and ships.From then on, it also meant a mobile device for flattening ground.[2]An early steamroller was patented by Louis Lemoine in France in 1859 and demonstrated sometime before February 1861.[3] In Britain, a 30-ton steamroller was designed in 1863 by William Clark and partner W.F. Batho.[4][5] Having failed to impress the British municipal road authorities it was transferred to Kolkata where it continued to work.[5]

The company Aveling and Porter was the first to successfully sell the product commercially and subsequently became the largest manufacturer in Britain.[4] In 1866 they produced a prototype roller with 3 foot-wide rollers fitted to the rear of a standard 12 nominal horsepower traction engine. This experimental machine was described by local papers as 'the world's first steamroller' and it caused a public spectacle.

Aveling & Porter refined their product continuously over the following decades, introducing fully steerable front rollers and compound steam engines at the 1881 Royal Agricultural Show. The move to asphalt for road construction resulted in the demand for steamrollers that could rapidly reverse so they could roll the tar while still hot.[7] Machines that could do this were introduced in the first decade of the 20th century.[7]

The majority of rollers were of the same basic 3-roll configuration, gear-driven, with two large smooth wheels (rolls) at the back and a single wide roll at the front (in actuality, the wide roll usually consisted of two narrower rolls on the same axle, to make steering easier). However, there was also a distinctive variant, the "tandem", which had two wide rolls, one front, one rear. Those made by Robey & Co used their standard steam wagon engine and pistol boiler fitted in a girder frame with rolls and a chain drive to produce a quick-reversing roller suitable for modern road surfaces such as tarmacadam and bituminous asphalt.[9] A number of Robey & Co. tandem rollers were modified to make a further variant, the tri-tandem, which was a tandem with a third roll, mounted directly behind the rear one. Robey supplied the parts, but the modification was undertaken by Goodes of Royston.[9] Ten tandem and two tri-tandem Robey rollers survive in preservation,[10] and one of the tri-tandems is known to have been used to construct parts of the M1 motorway.

In America, the Buffalo-Springfield Roller Company was a large builder. J. I. Case made a roller variant of their farm engines, but had a small market share. Other nations had makers including the Czechs, Swiss, Swedes, Germans (notably Kemna) and Dutch which produced steam rollers.

In the UK, a number of companies owned fleets of steam rollers and contracted them out to local authorities. Many were still in use into the 1960s, and part of the M1 motorway was made using steam rollers.[11] A few steam rollers were being used for road maintenance in the early 1970s, and this may go some way to explaining why diesel-powered rollers are still colloquially known as steam rollers today.

Many steam rollers are preserved in working order, and can be seen in operation during special live steam festivals, where operating scale models may also be displayed. At some of the UK steam fairs and rallies, demonstrations of road building using the old techniques, tools and machines are re-enacted by 'Road Gangs' in authentic dress. Steam rollers feature prominently in these demonstrations. The annual Great Dorset Steam Fair has a section dedicated to road-making machinery, including a line-up of working steam rollers.

Author Terry Pratchett instructed his collaborator Neil Gaiman that anything Pratchett had been working on at the time of his death should be destroyed by a steamroller. Pratchett's daughter and literary executor Rhianna Pratchett also stated that she had no desire to try to finish her father's work or continue the Discworld franchise without him. Accordingly, Pratchett's assistant Rob Wilkins brought Pratchett's computer hard drive to the Great Dorset Steam Fair, where a steamroller was driven over it.[15]

The steamroller has a strong symbolism of an irresistible, onward-pushing force. The Imperial Russian Army was nicknamed "steamroller" during World War One, as it was humongous by its size, and Russia initiated the war with an offensive. The "Russian Steamroller" is one of the personifications of Russia, along with the Russian bear, double-headed eagle and Mat Zemlya.

So, how does it exactly work? The extreme heat in the water will lift and liquefy the oil from the asphalt surface. This, then, allows the commercial degreaser to go in and dissolve or emulsify the grease that lies underneath the surface. As the oil or grease lifts up and out of the asphalt, the high pressure of the water washes it all away.

Clean asphalt contains no fillers and is an oil based liquid. It is primarily used in paving roads, waterproofing liquids, and paints. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.

Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions are shear sensitive and must be handled with care.

A firefighter walks past the scene of a steam pipe explosion on Lexington Avenue in New York City. Steam and mud were forced from the ground near Grand Central Station on East 41st street from Third to Lexington Avenue forcing people to evacuate the area and also causing subway delays.

Steam billows on Fifth Avenue in Manhattan on Thursday, July 19, 2018. A steam pipe exploded beneath the street, sending chunks of asphalt flying, a geyser of billowing white steam stories into the air and forcing pedestrians to take cover.

The 20-inch pipe was installed in 1932 and is part of nearly 100 miles of steam piping in the city. Fifth Avenue will remain shut down in the area for days as authorities work to clean up the toxic scene, officials said.

Three people were killed in the Gramercy Park section of Manhattan in 1989 when an explosion sent debris rocketing into the air. In 2007, a steam pipe installed in 1924 exploded in Midtown Manhattan during rush hour. One person was killed and more than two dozen were injured.

When you need compaction equipment to make your blacktop smooth and even, one of the asphalt rollers or compactors in this assortment might serve as an ideal solution. Check out the options within this selection to find a roller that fulfills your needs.

The rollers in this category are all riding, which means that they have seats on top. You direct these pieces of equipment with steering wheels, and they run on gas or diesel. You transport rollers into position by street-legal vehicles, and once they are in place, you drive them over wet asphalt to compact it into a flat and uniform surface.

The parts that are used to flatten asphalt are called drums. The riding forms of rollers that are included among these listings each have two drums, and one drum is usually wider than the other. Roller drums resemble tires except that they aren't soft and don't have any treads. Instead, they consist of flat steel surfaces that make asphalt flat as they move along. Over time, these pieces wear out, but you can replace them. Some types of rollers have vibrating drums, and this feature helps make asphalt smooth.

The CASE line of small double-drum asphalt rollers is ideal for parking lots, bike paths, tennis courts, and other small-to medium-size projects. CASE engineers designed each of four sizes (DV23, DV26, DV36, and DV45) to deliver the same level of productivity as its larger models, while helping to boost efficiency on jobs where space is tight, so maneuverability is paramount. ff782bc1db
