Laterite and murram roads In Africa and parts of Asia, laterite soils are used to build dirt roads . However laterite, called murram in East Africa, varies considerably in the proportion of stones (which are usually very small) to earth and sand.
· Use of such types of materials (laterite stone and Murram) for construction of low cost non-bituminous roads has been adopted as common practice in India. No notable change in fabric appearance was observed after the spreading of stones and rolling operations.
Not all laterite and murram roads are therefore strictly gravel roads. Laterite and murram which contains a significant proportion of clay becomes very slippery when wet, and in the rainy season, it may be difficult even for four-wheel drive vehicles to avoid slipping off very cambered roads into the drainage ditches at the side of the road.
LATERITE IN ROAD PAVEMENTS Laterite as a term has been applied indiscriminately in tropical highway engineering to any soil displaying a red coloration. Concretionary laterite is widely used as a sub-base and base material for gravel roads but, owing to confusion of terminology, the application of lateritic materials is frequently misunderstood.

Laterite or murram, having a tendency to harden upon exposure, is often satisfactory when traffic is light, but it tends to corrugate or break down with heavier use. * 1976, Norman Francis Hughes, Institution of Civil Engineers, Manual of Applied Geology for Engineers, Thomas Telford, ISBN 0727700383,

Murram is a synonym of laterite. As nouns the difference between murram and laterite is that murram is (east africa|india) laterite while laterite is a red hard or gravel-like soil or subsoil formed in the tropics that has been leached of soluble minerals leaving insoluble iron and aluminium oxides and hydroxides; used to make bricks and roads.

Rural roads for remote areas and developing regions (laterite or murram soil ''dirt'' roads in Africa) Military roads for reliable, secure patrol roads in difficult conditions Green roads for intermittent trafficking over grass shoulders, parking lots and low impact development
If pioneer roads are constructed, they are often built at the top of the construction width and are usually nothing more than a bull dozer trail. When considerable side hill fill construction is planned, however, the dozer trail should be located at the toe or base of the proposed fill.
· Other unhandled roads were dirt road, gravel road and laterite or murram road. Two types of roads considered in the subsequent illustrations are highway/ main-street (Type 1) and avenue (Type 2), whose actual widths were not less than 4 meters.

[5]:3 USES Road building Laterite road near Kounkane, Upper Casamance, Senegal The French surfaced roads in the Cambodia, Thailand and Viet Nam area with crushed laterite, stone or gravel. [19] Kenya, during the mid-1970s, and Malawi, during the mid-1980s, constructed trial sections of bituminous-surfaced low-volume roads using laterite in place of stone as a base course. [20]

Laterite may be ripped by crawler tractor, loaded by front-end loader, transported, spread and grid-rolled with a sheeps-foot roller to produce a sealed running surface. Rock may have to be blasted, loaded into one or more crusher(s), stockpiled, reloaded, transported, spread, and compacted.

(Improved unpaved roads include gravel roads, laterite roads, murram roads and macadamized roads). Compared to a gravel road, a dirt road is not usually graded regularly to produce an enhanced camber to encourage rainwater to drain off the road, and drainage ditches at the sides may be absent.

Murram pits are found along most roads, because the material (murram) excavated from them is used for building the roads. Whenever a road is re-carpeted with murram, the existing pits are either widened, or new murram pits are excavated. In any case, the
