In this article, we will explore the different techniques and methods used in soil stabilization, both physical and chemical, and their significance in promoting the longevity of asphalt roads.
Soil stabilization is the permanent physical and chemical alteration of soils to enhance their physical properties.
Stabilization can increase the shear strength of a soil and control the shrink-swell properties of a soil, thus improving the load-bearing capacity of a sub-grade to support pavements and foundations.
Stabilization can be used to treat a wide range of sub-grade materials from expansive clays to granular materials.
Stabilization can be achieved with a variety of chemical additives including lime, fly ash, and Portland cement, as well as by-products such as lime-kiln dust and cement-kiln dust.
1) Mechanical Soil Stabilization Technique:
Dense and well graded material can be achieved by mixing and compacting two or more soils of different grades.
Addition of a small amount of fine materials such as silts or clays enables binding of the non-cohesive soils which increases strength of the material.
Factors affecting the mechanical stability of mixed soil may include:
The mechanical strength and purity of the constituent materials
The percentage of materials and its gradation in the mix
The degree of soil binding taking place
The mixing, rolling, and compaction procedures adopted in the field
The environmental and climatic conditions
2) Compaction Soil Stabilisation Technique:
Uses mechanical means for expulsion of air voids within the soil mass resulting in soil that can bear load subsequently without further immediate compression.
Dynamic compaction is one of the major types of soil stabilization; in this procedure, a heavyweight is dropped repeatedly onto the ground at regular intervals to quite literally pound out deformities and ensure a uniformly packed surface.
1) Moisture Content. 2) Specific gravity of soil. 3) Atterberg’s limit. 4) Liquid limit. 5) Particle size distribution. 6) Preparation of reinforced soil sample. 7) Determination of shear strength.
1) Moisture Content
Soil tests natural moisture content of the soil is to be determined. The natural water content also called the natural moisture content is the ratio of the weight of water to the weight of the solids in a given mass of soil.
2) Specific gravity of soil.
The specific gravity of soil is defined as the unit weight of the soil mass divided by the unit weight of distilled water at 4°C.
3) Atterberg’s limit
Atterberg's limits are a set of tests used in soil mechanics to determine the plasticity and compressibility characteristics of soil
1. It improves the strength of the soil, thus, increasing the soil bearing capacity.
2. It is a lot of economical each in terms of price and energy to extend.
3. Bearing capacity of the soil instead of going for deep foundation or raft foundation.
4. It offers more stability to the soil in slopes or other such places.
5. Sometimes soil stabilization is also stop soil erosion or formation of mud, which is extremely helpful particularly in dry and arid weather.
Stabilization Is Also Done For Soil Water-proofing; This Prevents Water From Entering Into The soil And Hence Helps The Soil From Losing Its Strength.
It Helps In Reducing The Soil Volume Change Due To Change In Temperature Or Moisture content.
Stabilization Improves The Workability And The Durability Of The Soil.

A review on stabilization of soil using bio enzymeeSAT Journals
Abstract In developing countries like India the most important requirement of any project after performance criteria is its economical feasibility and serviceability criteria. The conventional methods are time consuming and are not economically feasible. Hence there is a need to discover the other possible ways to satisfy the performance as well as economical criteria. In this paper, popularly available bio-enzymes and their effect on engineering properties of soil are discussed. The stabilization of soil with bio-enzyme is a revolutionary technique which becoming popular worldwide. Recently there are many bio-enzymes available for soil stabilization such as renolith, Perma-Zyme, Terra-Zyme, Fujibeton etc. These enzymes have been proven to be very effective and economical. Another advantage of the bio-enzyme is that these are environment friendly. When these bio-enzymes are mixed with soil they alter its engineering properties. Their efficiency depends upon the amount of dose, type of soil available and field conditions. The use of bioenzyme in soil stabilization is not very popular due to lack of awareness between engineers and non availability of standardized data. However, recently some bio-enzyme stabilized roads were constructed in various parts of India, which are performing very well. Keywords: Bio Enzyme, Nontraditional Soil Stabilizer.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
