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.
In view of this, lateritic soil was collected from Heaven Nkwanta in the Western region of Ghana. The soil sample was treated with burnt coconut husk ash (CHA) collected from the local coconut sellers from Tarkwa Nsuem Municipality.

There is a wide diversity of opinion concerning nomenclature, testing procedures and acceptance criteria, as well as great variation in engineering behaviour.
The advantage of using lime as a soil stabilizer is basically concerned with many reasons such as reduced construction or operational cost during process of the project especically, reduce water use energy consumption and a reduction of Co2 emissions as well as saving time of operational processes.
Aug 30, 2017· Later the term was used and misused for a range of reddish soft and hard soil materials in the tropics. The specific soft material that hardens on exposure has been renamed 'plinthite' in soil taxonomy. Laterite has been widely used as construction material in southeast Asia throughout history.
the confidence with which laterite can be used for road construction is diminished largely because the term may apply to a material with a range of geotechnical properties. Nonetheless, certain types of this material are eminently suitable for use in the construction of road pavements in Africa for which a commonly agreed definition is
Cement as a stabilizer can be used to make up for the strength of laterite by addition of 0.5 -7.5% of cement to the laterite soil (Adeboje et al, 2013).Overdependence on the utilization of industrially manufactured soil improving additives (such as cement and lime) has kept the cost of construction of stabilized road high.

STABILIZATION WITH LIME-CEMENT AND LIME-BITUMEN. In a road pavement construction project, the advantage of using combination stabilizers is that one of the stabilizers does not perform its effectiveness properly, the other one is able to compensate when treating a specified characteristics of a given soil.
January 2018). However, failure of lateritic roads in developing countries including Rwanda has stressed the need for detailed geotechnical evaluation of lateritic soil prior its use in road construction in order to choose appropriate soil materials for the pavement structure (Ademila, August 2017). For a
these lateritic soil to be used in road pavement and building construction materials. The California bearing ratio (CBR) is a test to specify the mechanical strength of a soil. It is ratio between the actual pressure and the standard pressure under a constant penetration. It is usually done by a continuous load from the penetration piston.
