Abstract
Most of the Niger Delta area in Nigeria are undergoing rapid industrialization.
Transportation demands are on the increase, requiring long lasting pavements. Laterites are generally
being used for most embankments and road fills. However, in areas of the clayey laterites, not meeting
specification, it will be cheaper to stabilize insitu instead of importing laterite. This paper presents the use
of fly ash to stabilize the laterite to produce cement treated road base and roller compacted concrete
(RCC) without cement
