Abstract

This research focus on improving the weaknesses of soft clay soils by using proper recycled material as a stabilization agent for strengthening purpose. Therefore, Diaper’s Back Sheet Layer Wastes (DBSLW) were used as the agent of soil stabilization. In this study, series of laboratory test were conducted to evaluate the optimum size and content of DBSLW as a strip reinforcement to increase the strength of Batu Pahat Soft Clay (BPSC). Testing program involves obtaining the physical properties of BPSC followed by California Bearing Ratio (CBR) test to determine the strength of BPSC with and without the addition of DBSLW. Result shows that the optimum size for DBSLW is 10 mm x 30 mm while the optimum content is 0.5%. At 15 mm penetration, sample with diapers strip of 10 mm x 30 mm dimension record 4.10 kN CBR value compare to 1.64 kN CBR value of untreated soil, 2.5 times stronger than untreated soil. Results of CBR tests demonstrated that inclusion of DBSLW strips in soil with optimum amounts and size improved strength and deformation behavior of soils substantially. The proposed technique could be used to advantage in road construction, industrial yards, and building structure.

Highlights

Soil stabilization is the process which is used to improve the engineering properties of the soil and making it become more stable
Other material byproducts used in Stabilization include lime-kiln dust (LKD) and cement-kiln dust (CKD) [1]
Stabilization is being used for a variety of engineering works, the most common application being in the construction of road and airfield pavements, where the main objective is to increase the strength or stability of the soil and to reduce the construction cost by making best use of locally available materials

Summary

Introduction

Soil stabilization is the process which is used to improve the engineering properties of the soil and making it become more stable. Soil stabilization is required when the soil available for construction is not suitable for the intended purpose. It includes compaction, pre consolidation, drainage and many other such processes [1]. Stabilization can increase the shear strength of a soil and control the shrink-swell properties of a soil, improving the load bearing capacity of a sub-grade to support pavements and foundations. This process is accomplished using a wide variety of additives, including lime, fly-ash, and Portland cement. Stabilization is being used for a variety of engineering works, the most common application being in the construction of road and airfield pavements, where the main objective is to increase the strength or stability of the soil and to reduce the construction cost by making best use of locally available materials
