MECHANICAL PROPERTIES OF FLY ASH STABILIZED CLAYEY LATERITE

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
