TL;DR: In this article, the authors addressed the some fundamental and success soil improvement techniques used in civil engineering field and addressed the failure to identify the existence and magnitude of expansion of these soils in the early stage of project planning.

TL;DR: In this article, the authors explored improvements in the physical properties of UKM residual soil using small amounts of nanocarbons, that is, carbon nanotube (MWCNTs) and carbon nanofibers (CNFs).

TL;DR: In this paper, the effects of Portland cement additive on properties of base layer using laboratory mechanistic evaluation of stabilized soil mixtures were investigated and the results revealed that by adding Portland cement, the mechanical properties of the mixture have improved where the UCS is found to be an important quality indicator.

TL;DR: In this article, the effects of the addition of a carboxylated styrene-butadiene emulsion (Tylac® 4190) and Portland cement on the long-term performance of road base were investigated.

TL;DR: In this paper, bio-enzymes have emerged as a new chemical for soil stabilization They are organic materials which are supplied as concentrated liquid and claim that their products are effective, environmental friendly (non-toxic), cost effective and convenient to use They improve the compressive strength, reduce compaction effort and increase the density thus reducing the permeability as well
