Geochemical Analysis of Ilaro-Papalanto Highway Subgrade

Stabilization of Subgrade Soil for Highway by Recycled Polyester Fiber

Subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (PET) bottles produced by household sectors. This research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and California Bearing Ratio...

Research on the Mechanical Analysis of Weathered Rock Filling Subgrade on Highway

With the rapid development of national economic construction, traffic network is extending continuously, and the scope of the highway construction is gradually shifting from plain to the mountains. However, weathered rock occupies heavily along highway in mountainous area, and high quality subgrade filling is extremely short, thus a large amount of subgrade filling needed for subgrade high-fill...

Occurrence of shale soils along the Calabar-Itu highway, Southeastern Nigeria and their implication for the subgrade construction

This study concerned a stretch of 17 km of a 94-km highway alignment in Southeastern Nigeria that has a high incidence of pavement failure arising from subgrade failure. The subgrade of this section of the roadway is composed of Ekenkpon shale, New Netim marl, and Nkporo shale. Under the Unified Soil Classification System, the shales classify as OH (organic clay) and the marl classifies as MH (...
