What Is Macadam?

Macadam is a road surface that was first invented by a Scottish engineer, John Loudon McAdam. It has since been a common method of road construction throughout the world.

A layer of crushed stone and gravel, bound together with tar or bitumen. The material is generally laid on top of a base course made up of small stones or sand.

This method of road construction has a number of advantages over the other options. For one, it is less expensive to construct. Moreover, it has a much longer service life.

In addition, it is very easy to install and maintain. This type of material is also environmentally friendly and can be recycled.

Another advantage of this road surface is that it allows for a much smoother ride on vehicles. Additionally, it is cheaper to build than other road surfaces, making it a popular choice for highways.

A road constructed by laying layers of crushed stone and gravel, bound together with hot tar. The material was initially designed for use with carriages and horse-powered travel, but it became a popular option for automobile traffic as well.

Despite its popularity, this type of road surface had some drawbacks. For one, it was often covered with dust from the wheels of cars and trucks.

Fortunately, the industry made some significant advancements in the early years of the twentieth century. Eventually, most roads were paved with asphalt. While some countries still use macadam, most of the world now uses this more modern paving material.
