This road was completed in 1823, using McAdam's road techniques, except that the finished road was compacted with a cast iron roller instead of relying on road traffic for compaction. [15] The second American road built using McAdam principles was the Cumberland Road which was 73 miles (117 km) long and was completed in 1830 after five years of ...
John Loudon McAdam, 1830, National Gallery, London. John Loudon McAdam (23 September 1756 [1] – 26 November 1836) was a Scottish civil engineer and road-builder. He invented a new process, "macadamisation", for building roads with a smooth hard surface, using controlled materials of mixed particle size and predetermined structure, that would be more durable and less muddy than soil-based tracks.
Tarmacadam is a concrete road surfacing material made by combining tar and macadam (crushed stone and sand), patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 19th century.
The Design Manual for Roads and Bridges (DMRB) is a series of 15 volumes that provide standards, advice notes and other documents relating to the design, assessment and operation of trunk roads, including motorways in the United Kingdom, and, with some amendments, the Republic of Ireland. It also forms the basis of the road design standards ...
A plank road. The Plank Road Boom was an economic boom in the United States that lasted from 1844 to the mid 1850s, largely in the Eastern United States and New York.In the span of ten years, over 3,500 miles (5,600 km) of plank road were built in New York—enough road to go from Manhattan to California—and more than 10,000 miles (16,000 km) of plank road were built countrywide.
St. Augustine Road was paved as a macadam road from George Street to the right-angle turn by 1910. [3] The remainder of the road to St. Augustine and MD 310 east of St. Augustine were constructed as a 12-foot-wide (3.7 m) macadam road by Cecil County with state aid by 1915. [4] [5] MD 342 was resurfaced with bituminous concrete in 1988. [6]
In 1905 there were 68,000 mi (110,000 km) of roads in Michigan. Of these roads, only 7,700 mi (12,000 km) were improved with gravel and 245 mi (394 km) were macadam. The state's "statute labor system" was abolished in 1907. Under that system, a farmer and a team of horses could work on road improvements in place of paying road taxes.
The plan was approved by the Spanish Crown in 1860 and it included the creation of "first order" and "second order" highways. In 1860, the central government commissioned engineer Niceto Blajot to design the paved version of Carretera Central between Ponce and Juana Díaz, which until then was a dirt and gravel road. [2]: 6
