SummaryIn Kenya 1974/5 and in Malawi 1984/5 trial sections of bituminous-surfaced low volume roads were constructed using as-dug laterite in place of stone or stabilized material as a base course.The laterite did not conform with any accepted specifications but performed equally well when compared with adjoining sections of road using stone or stabilized material as a base.The construction procedures employed are described. A period of 4–6 weeks between the compaction of the base and its… Expand
Research into the properties of lateritic gravels and their impact on pavement design
Laterites are used extensively in the tropics as road building materials in unbound base, sub-base layers and in surface layers. However, most base course specifications usually require the provisionExpand
Stabilization of Colombian lateritic soil with a hydrophobic compound (organosilane)
Abstract In Vichada state, Colombia, the lack of suitable construction road materials has forced the local authorities to use local materials, such as laterite, that has not been yet completelyExpand
A Review of Specifications for Lateritic Materials for Low Volume Roads
Most laterite or lateritic soils do not comply with traditional specifications for road layers. This is a particular problem when materials are required for low volume roads. However, experience withExpand
Comparison Characterization of A-6(10) Laterite Soil Stabilized With Powermax Cement and Hydrated Lime Separately
This work presents the comparison of A-6(10) laterite soil stabilized with Powermax cement and hydrated lime separately in percentages of 6%, 8%, 10%, 12% and 14%. It also considered the stabilizedExpand
Low-cost local road materials in southern Africa
SummarySouthern African natural gravel and soil road materials are mostly residual soils, residual weathered rocks or pedocretes which are inferior in quality to materials found in northern EuropeExpand
Assessment of Quality of Some Laterites in Northeastern Nigeria by Multivariate Analysis of their Geotechnical Index Properties
The index properties of lateritic soils derived from sandstone, limestone, gneiss, granite, basalt, and migmatite in northeastern Nigeria were assessed for selecting the type with the bestExpand
Assessment and mapping of the high background radiation anomaly associated with laterite utilization in the south coastal region of Kenya
Abstract Laterite is commonly used in Kenya and other tropical countries as an aggregate material for road paving. However, the use and relocation of laterite and other geological materials from highExpand
A mechanistic empirical method to predict permanent deformation on tropical soils on pavements
This paper presents several permanent deformation tests of compacted tropical soils used for road pavements in Brazil. It is proposed a mathematical model to predict permanent deformation based onExpand
Deposits Formed by Sedimentation and Weathering
Weathering, transport, and sedimentation are other processes that lead to effective fractionation. Little wonder important metal deposits are found in sediments. Resources such as sand, gravel, andExpand
Evaluation of strength properties of oil-contaminated sands upon stabilisation with laterite soil
Commercial decontamination procedures of oil contaminated sands can be costly. In this study, the inexpensive laterite soil was used as the stabilization additive, which brought notable results in ...
