“…Stone columns installed at a distance of less than 3.66m can cause problem such as high lateral pressure and displacement of adjacent structures [51]. Geo-technical problems such as excessive settlement, liquefaction and low bearing capacity are usually observed with stone column [53]. In general, there is still lots of improvement needed for the current ground improvement techniques, the current ground improvement technique is very expensive and requires lots of skilled labor.…”

Flexible pavement failure has been a major problem encountered in various countries. Some common distress which had been listed are cracking and rutting. The causes of this distress are due to moisture, weak sub-grades and poor construction quality. High amount of distress in the pavement however is likely to cause dis-comfort for the passengers, higher accident rate and heavy traffic. Study suggested that, flexible pavement failure can be reduce, through maintenance of the wearing course of the pavement, improving the base, sub-base layer or the sub-grade soil underneath of the pavement. However, high production or material cost, high construction cost, excessive settlement, or weak inter-molecular bonds in the flexible pavement are some of the common problem encountered with the current improvement techniques. This significance difference of this review paper compare to other is that, in this review paper it focuses on the flexible pavement failure, the different types of improvement method currently applied. Consequently, it further recommend flexible pavement improvement method through by reducing the sub-base layer thickness and inclusion of light weight material in the sub-base layer so that, the settlement of the pavement is reduced.

“…Usually, the modified properties are strength, stiffness, permeability, workability (willingness for compaction), resistance to frost, etc. [1][2][3][4]. The type of ground improvement/soil treatment depends on the demands of the structure to be built, the soil type, the available materials and tools, and the local tradition and experience.…”

Abstract.A possibility of in-situ mechanical improvement for reducing the liquefaction potential of silty sands was investigated by using three different techniques: Vibratory Roller Compaction, Rapid Impact Compaction (RIC) and Soil Mixing. Material properties at all test sites were investigated before and after improvement with the laboratory and the in situ tests (CPT, SDMT, DPSH B, static and dynamic load plate test, geohydraulic tests). Correlation between the results obtained by different test methods gave inconclusive answers.
