Compressibility characteristics of Sabak Bernam Marine Clay

Abstract

It is important to carry out this study since this type of marine clay covers large coastal area of west coast Malaysia. This type of marine clay was found on the main road connecting Klang to Perak and the road keeps experiencing undulation and uneven settlement which jeopardise the safety of the road users. The soil is indicated in the Generalised Soil Map of Peninsular Malaysia as a CLAY with alluvial soil on recent marine and riverine alluvium. Based on the British Standard Soil Classification and Plasticity Chart, the soil is classified as a CLAY with very high plasticity (CV). Results from laboratory test on physical properties and compressibility parameters show that Sabak Bernam Marine Clay (SBMC) is highly compressible, has low permeability and poor drainage characteristics. The compressibility parameters obtained for SBMC is in a good agreement with other researchers in the same field.

Evaluating Engineering Properties of Marine Clay Soil at Malacca and Proposed Methods of Quality Enhancement

“…This paper serves as a comparison between studied marine clay and several types of marine clay samples taken from various South East Asian locations [1]- [10], [12], [13], [16], [17], [20], [21], [24]- [35], [37]- [39], [42]. Significant variations of the geotechnical parameters have been found for the same region, even if not of the same borehole.…”

“…Some results have displayed odd values compared to the general tendencies seen for Arkine of Japan [2]- [4], Ashikari (Japan) [35], Oita Prefecture (Malaysia) [2], and Klang (Malaysia) [24]. Nevertheless, the value of liquid limit w LL is found to be not less than 60% [3], [30], [35]; whereas the plastic limit w PL is below 30% [9], [10], [17], [20], [21], [32], [34], [37]. Similarly, the natural water content wn is within the range of liquid limit if not higher [4], [5], [7], [10], [12], [16], [17], [20], [30], [32], [39].…”

Engineering Properties Investigation of Soft Clay as Potential Subgrade Material

“…The compression index or recompression index can be found by performing an oedometer test in a laboratory. Diana et al [15] have used soft clay, a type of marine clay, to study the characteristics of the soft clay in terms of compressibility through a 1-D consolidation test. The results of the study found that the compression index value was 0.614 and the recompression ratio value was 0.169.…”
