Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which single-sized crushed stone layers of small angular stones are placed in shallow lifts 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 binder to keep dust and stones together.

Gravel Road Construction. Although gravel road construction can be done anytime on any surface, a smooth, long-lasting roadway requires the right process. Like any other building project, a gravel road starts with the foundation. The other three stages are sub-grade material, sub-base …
In the base you want 40-80% hard stone graded from 1/4 to 3 inches in diameter, but on the surface use smaller size stone. The standard state specs call for 3/4 inch aggregate for surface gravel (crushed stone) with 20-60% sand (less than 1/4 inch) and 8-15% fines.
Since early 1920s, asphalt road surface construction is the most popular type. Asphalt construction technique gives a layer of thick gravel base on top. ROI of this type of road construction includes low noise during pavement, relatively low cost material, and top one is …
2A Sub Base. This material has a 2 inch top size. It is a mixture of coarse stone and crushed stone dust. Used as a road base, under slab, driveway or walking paths. Will drain. Has a structural coefficient. Used where stability and drain ability are concerns. Primarily a clean material.
Whether serving as base stone for a library or assisting erosion control in waterways, crushed stone is one of the most vital and versatile materials in construction projects. Other applications include roadways, water filtration and mineral production for consumer products like toothpaste and antacids.
It is a cost effective alternative for stone base material. After several years of research and development, and hard work by the quality control and materials production teams, P. Flanigan & Sons RC-GAB was approved in September 2010 for use on Maryland State Highway Administration projects.
