Experimental study on strength performance of soil reinforced with coconut fibre for PANCHOR–MUAR road
Laterite soil is a typical earthfill material used in road construction base and sub-base layers. Regrettably, such soil becomes soft and saturated under high water content and causes an unsatisfactory performance in withstanding loads from proposed structures. Recently, the use of fibres to impr...

| description | Laterite soil is a typical earthfill material used in road construction base and sub-base layers.
Regrettably, such soil becomes soft and saturated under high water content and causes an
unsatisfactory performance in withstanding loads from proposed structures. Recently, the use
of fibres to improve the soil layer, thereby increasing its geotechnical properties, has been
attracting worldwide attention. Therefore, the present study takes a holistic approach to utilise
coconut fibre (CF) as sustainable fibre reinforcement to enhance the strength performance of
local laterite soil at Panchor - Muar, Johor. It then is used as an earthfill material for construction
work. This research focuses mainly on investigating the compaction parameters and bearing
capacity of CF–laterite soil. Standard compaction test and California bearing ratio (CBR) test
were performed on soil randomly included with three different CF proportions (0%, 0.5%, and
1.0%). Results indicate that the optimum moisture content increased and the maximum dry
density decreased as the proportion of CF increased to 1.0%. The CBR value of the reinforced
soil recorded a significant increase to 17.42% and 26.14% after being mixed with 0.5% and
1.0% CF proportions, compared with unreinforced soil (7.58%). The coconut fibrereinforcement
makes the stabilised soil ideal as a subbase material for road pavement
applications. In addition to enhancing soil strength efficiency, CF reuse would also reduce the
amount of agricultural waste disposal to landfills and prevent environmental problems. |
