• Abstract:

  The Study Was Undertaken To Evaluate The Effect Of Geofibres In The Reconstruction Of Road. Samples Of Sub- Grade Soil Were Collected Within The Failed Section Of Road. Geofibres Was Added To The Soil In An Increasing Order Of 5% , 10% , 15% And 20% By Weight Of The Soil In A Single And Double Layered System. The Sub- Grade Soil Samples And Sample Stabilized With Geofibres Was Subjected To Laboratory Testing. The Test Conducted Were Sieve Analysis Test, Specific Gravity Test, Atterberg Limit Test, Compaction Test And CBR Test. Results Obtained From Sieve Analysis Test Classified The Samples As A- 7- 6 According To AASHTO Soil Classification System And CH (clay Of High Plasticity) According To Unified Soil Classification System, The Specific Gravity Of The Sub- Grade Soil Was 2.66, The Liquid Limit, Plastic Limit And Plasticity Index Of The Sub- Grade Soil Was 34.8% , 21.5% And 13.3% , The Maximum Dry Unit Weight Of The Sub- Grade Soil Increased From 20.7kN/m3 To 22.67kN/m3, For The Single Layered Disposition Of Geofibres While For The Double Layered Disposition Of Geofibres, The Maximum Dry Unit Weight Of The Sub- Grade Soil Increased From 20.7kN/m3 To 23.2kN/m3. The CBR Of The Sub- Grade Soil Increased From 25.8% To 32.6% For The Single Layered System, 27.4% To 34.8% For The Double Layered. The Study Therefore Recommends The Use Of Geofibres In Road Construction As Improvement In The Strength Properties Of The Sub- Grade Soil Was Observed.
