Macadam is a type of road construction pioneered by Scottish engineer John Loudon McAdam c. 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to ...
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.
Tar-grouted macadam was in use well before 1900 and involved scarifying the surface of an existing macadam pavement, spreading tar, and re-compacting. Although the use of tar in road construction was known in the 19th century, it was little used and was not introduced on a large scale until the motorcar arrived on the scene in the early 20th ...
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 first section of MD 161 to be improved was 1 mile (1.6 km) of macadam road from Shuresville Road in Darlington south to Price Road built by 1910. [3] Two sections of macadam road were constructed in 1928. One segment was constructed from Shuresville Road in Darlington north to US 1.
[5] [6] The Uniontown Road from New Windsor to near the modern MD 75–MD 84 junction was paved in macadam as a state aid road in 1911. [5] The highway was extended south as a state-aid road from Fountain Mills toward Hyattstown in two sections; the first 1.5-mile (2.4 km) section was completed as a macadam road by 1915. [6]
The first segment of the modern MD 281 was constructed as a macadam road east from US 40 (now MD 7) on Main Street to Big Elk Creek between 1930 and 1933. [ 6 ] [ 7 ] In 1948, the Maryland State Roads Commission , which at the time maintained the major county highways in Cecil County, reconstructed much of Red Hill Road as a gravel road in 1948 ...
