If you’re looking to have your asphalt paved by a professional, then you’ve come to the right place. Our asphalt experts will ensure that you get the best product possible at the most reasonable price.
The first step in our process is to make sure that you are properly educated about your upcoming project. To do this, we’ll need to know a little bit about where you live.
We’ll also need to know a few things about how much traffic your driveway will see. Will there be many pedestrians walking down your driveway? Are you concerned about the safety of children or pets? These are important considerations when choosing an asphalt company.
The term asphalt is used to describe a number of products derived from the same source: bitumen.
Bitumen is a dark, viscous material found naturally in rock formations in many parts of the world. It is also sometimes called asphalt or coal tar depending on the geographical location. Bitumen is the heaviest and thickest form of petroleum and when mixed with aggregate (stones and sand) it becomes asphalt concrete.
Asphalt has many uses, but its primary use is as an aggregate mixed with bitumen and used for road building. Asphalt has become a crucial part of new road construction across the world. Almost every major international city uses asphalt in its roads, highways and runways because it is so durable and long lasting. In fact, cities like Rome have roads that were built almost 2000 years ago using asphalt!
Bitumen was also used by ancient people as a sealant, coating everything from Egyptian mummies to water pipes to boats. Asphalt was even used by Native Americans as an adhesive for arrowheads!
JOSEPH ASPDIN (1778-1855)
Joseph Aspdin was a bricklayer who patented the first true Portland cement, in 1824. He was born in Leeds, England on December 12, 1778. In 1810 he set up in business as an independent bricklayer in Leeds, and in 1813 he secured a patent for his invention.
By 1821 Joseph had established a factory at Wakefield to manufacture his “Roman” cement. By 1824 Aspdin had moved to a larger factory at Kirkstall and taken out a new patent. The patent document described the product as “Portland Cement,” because the concrete it produced looked like Portland stone when it was set.
Joseph Aspdin was a Leeds-based bricklayer who patented “Portland Cement” on 21 October 1824. This was the first time that a man-made material had been patented in the UK, but it took another 60 years for Portland cement to become widely used in construction.
Joseph Aspdin was a man of humble origins who rose to become one of Leeds’ most important people in the 19th century.
He was born in 1778, one of nine children brought up in Marsh Lane, off Briggate. His father, William, was a stone mason and his mother worked as a weaver at Kirkstall Forge.
In 1798 Joseph married Mary Wade, the daughter of a farmer from Bramley. The couple had ten children between 1800 and 1821. Joseph became a bricklayer, working on the streets around Boar Lane and Kirkgate Market. But by 1815 he was working as an engineer with his brother William at Swinegate Foundry.
In 1817 Joseph set up his own business making steam engines but after several years of financial setbacks he decided to return to his old trade as a bricklayer and by 1823 had found work at Middleton Railway near Leeds. He lived nearby in Hunslet
Joseph Aspdin was an English cement manufacturer who obtained the patent for Portland cement on 21 October 1824. The patent was instituted on 16 December 1824.
Aspdin invented the product by burning finely ground chalk and clay until the carbon dioxide was removed, leaving behind calcium oxide, or quicklime. He called it Portland cement because it looked like the stone quarried on the Isle of Portland in Dorset, England.[1]
Portland cement is a hydraulic cement produced by pulverizing clinkers consisting essentially of hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate as an interground addition.[2][3]
The name “Portland” cement is also recorded in a directory published in 1823 being associated with William Lockwood,[4] and others had previously been using the name. Aspdin’s son William first made Portland cement in 1842[5] but did not patent it until 1859.[6]
Joseph Aspdin was an English cement manufacturer who obtained the patent for Portland Cement on 21 October 1824. The invention was not original. Aspdin simply burned finely ground chalk and clay until the carbon dioxide was driven off (this is known as calcination), and then ground the resultant material into powder. He called the product Portland cement because it had a similar colour to Portland stone when it set. Portland stone is a limestone from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset, England. The name ‘Portland’ cement is also recorded in a directory published in 1823 being associated with a William Lockwood and possibly others. However, Aspdin’s son William later claimed that, as his father was first to use the name “Portland” cement, Joseph Aspdin had been its inventor.
Aspdin’s cement was superior to lime mortars available in Britain at the time, but tests carried out by James Frost in 1833 found that it was unsuitable for use on its own under waterlogged conditions. These tests led eventually to the development of modern Portland cement by William Aspdin
