USE OF WASTE GLASS IN IMPROVING SUBGRADE SOIL PROPERTIES

Effects of Glass-Fiber Reinforced Polymer and Waste Polypropylene Plastic Particles on Geotechnical Properties of Clayey Soils for Using Subgrade in the Pavement

The fine-grained soil including the problematic ones can cause many difficulties in project accomplishment. Settlement and swelling are among the problems of the fine-grained soils. The present study compared the effects of the polypropylene waste plastic (PWP) and glass fiber reinforced polymer (GFRP) on geotechnical properties of the clayey soils for the subgrade design. To this end, the PWP ...

Improvement of Kaolinite Clay Subgrade Using Coir Fiber Waste

Abstract-Since highways are widely used modes, it is necessary that it should be maintained properly. Subgrade being the support for the whole pavement, it needs the utmost care in its construction. Many suggestions have been put forward by various scientists to improve the subgrade. The usually adopted methods are stabilization methods. This paper deals with the improvement of properties of ka...

Spatial Correlation of Mechanical Properties of subgrade Soil for Foundation Characterization

Evaluation of Properties of Soil Subgrade Using Dynamic Cone Penetration Index – A Case Study

––The performance of pavements depends to a large extent on the strength and stiffness of the subgrades. Subgrade strength (CBR) plays a major role in pavement design. Since determination of CBR value in field requires need of equipment and also time consuming alternatively one can be predict CBR value of subgrade in field from other soil support tests namely Dynamic Cone Penetrometer Index (DC...
