the effects of poor drainage on road pavement. Poor drainage causes early pavement distresses
leading to driving problems and structural failures of road as pointed out by researchers. To prevent
or minimize premature pavement failures and to enhance the road performance, it is imperative to
provide adequate drainage. The review covered: importance of highway drainage system in roa
d
construction, requirements of highway drainage system, and effects of bad drainage system on
roads. The research pointed out areas of concern for drainage designers and road engineers
that are
of great importance during road construction to ensure that, the constructed road is put to use
without failure before the actual design life. The review concluded that effect of poor drainage
condition on a road is very adverse. It causes the failure of road in different way
s and as well
economic hardship on inhabitants of affected communities with devastating effect of sicknesses as
a result of breeding of mosquito especially on streets in towns with poor drainage capacity. Proper
drainage system provided to the road increases the life of roads. But the improper drainage system
causes the failure of the road at its early edge. Therefore effective engineering pr
actices should be
considered necessary during design, construction and management of roads and drainage channels.

Construction of standard quality roads require a lot of commitment, labour, good planning with good engineering and construction practices. Modern roads are engineered systems designed to spread or carry wheel loads on surface layer systems which are stiff down to the less stiff layers called the sub grade. The subgrade which is an important part of the road structure usually is considered to be a weak layer, since road construction is executed on the soil, different types of soils are met along the stretch of a proposed alignment, however, black cotton soil also known as expansive soils seem to be the most challenging type of soil encountered by engineers due to the presence of montmorrillonite which is a mineral that is highly unstable thus leading to shrinking and swelling of this type of soil on slight change in moisture content of back cotton soil. Since it is not only uneconomical to excavate soils with poor engineering characteristics and replace from borrow sites with soil having better engineering properties but as well constitute environmental hazards, the use of material wastes that would have constituted such environmental hazards to the society through indiscriminate disposal or wrong methods of incineration are put back into the soil to improve the engineering properties such as California Bearing ratio(CBR), Unconfined Compressive strength(UCS), plasticity, liquid limit, maximum dry density (MDD), optimum moisture content(OMC) etc. The improvement of unstable soil is thus called soil stabilization. AIM: This research work is geared towards presenting a literature review on effect of agricultural solid wastes (ASW) on stabilization of expansive soil, putting in place the gap that needs to be bridged with more research on more (ASW).
