Top Five Common Road Construction Methods CBR Testing UK ...

This is an advancement of the earth road. It is common in semi-rural, semi urban and rural areas. Here you use the same process as the earth road but you add a layer of gravel after the earth is compacted. One major advantage that this road has is the lack of dust and that it does not get slippery when it rains. Its maintenance cost is also low and its construction is not

Road construction - Designing Buildings Wiki

Road construction techniques were gradually improved by the study of road traffic, stone thickness, road alignment, and slope gradients, developing to use stones that were laid in a regular, compact design, and covered with smaller stones to produce a solid layer. Modern roads tend to be constructed using asphalt and/or concrete.

Road surface - Wikipedia

Telford's method of road building involved the digging of a large trench in which a foundation of heavy rock was set. He also designed his roads so that they sloped downwards from the centre, allowing drainage to take place, a major improvement on the work of Trésaguet. The surface of his roads consisted of broken stone. McAdam developed an inexpensive paving material of

Gravel in construction - Designing Buildings Wiki

Gravel, along with sand, is used for the manufacture of concrete, as well as for mixing with asphalt as part of road construction. It can be used as the base layer for roads before being covered with tarmac, and is also commonly used to surface roadways, especially those in rural areas and in icy conditions.
