Abstract
The heave of expansive soil information is a fundamental part of the preparation of a foundation design to accommodate the anticipated volume change and consequences associated with the foundation movement over the design life of the structure. The one-dimensional oedometer is the most widely accepted method to identify and evaluate the amount of swell that may occur. Although the oedometer is used extensively for evaluating the amount of heave, the procedures used are quite varied, and few of the methods have been validated experimentally. An objective of this research study is to briefly explain common practices and existing heave prediction by oedometer methods and then, to validate by experimental laboratory heave tests using soil sample from Ngawi. The two prediction methods provided results that represent low and upper bound predictions of the actual soil heave movement in the laboratory. The difference between the prediction with heave measurement is about 29,50% and 45,02%, respectively.
Highlights
The expansive soil has a potential to increase and decrease in volume under increasing and decreasing water content and as well as suction
The purpose of this paper is to review recent research into the heave prediction focused on the oedometer method and validated the method experimentally, aiming to provide the most suitable method that can be used for predicting heave of the expansive soil from Ngawi, East Java
The Nelson et al prediction method was closer to the heave measurements
Summary
The expansive soil has a potential to increase and decrease in volume under increasing and decreasing water content and as well as suction. The swelling pressure will be imposed on infrastructures such as the foundation slab, highway pavements, tunnels, pipelines, and results in extensive damages. Expansive soils cause more damage to structure, to light buildings and pavements. The reliable determination or estimate of the swelling pressure and the amount of anticipated heave that soil will undergo when subjected to variance in water content is the key information that determines the success of the remediation techniques and procedures [1] and is essential for the development of more effective and economical designs of structure on expansive soil [2]. Several procedures have been proposed to estimate the swelling pressure, swell potential and soil movement prediction.
