Road Construction – Soil Stabilization

It is important to have a smooth surface and stabilize soil in road construction so that erosion can be prevented.

Selection of stabilization technique should be selected to achieve good soil properties. This selection depends on many factors such as types of soil to be stabilized, Availability of stabilizing materials, Availability of construction equipment, Environmental conditions of that area, Structure of pavement, Volume and distribution of traffic, Period of project, Budget of project. All this factors to be checked to select stabilization method.

Mix design is as important as other factors. Mix design should be done in such a way that great durability and stability can be obtained. Which methods are we using for mix design will also play a major role for stabilization. Additives are added to the mix for meeting the requirements but this will increase cost.

Thickness of stabilized soil layer is again an important factor and design of that is less remarkable in stabilization. The thickness layer is kept equivalent to granular base-course considering the factors such that mix properties, environmental conditions, types of traffic, design period of pavement etc. This factors will not cause any difficulties in stability and durability but if the stabilized mix is weaker than the requisite value, it is not recommended to follow the above-mentioned considerations and the design for thickness should be done separately.  

However, there is no separate method to design the thickness of such poor stabilizing mixes. So, the mixes such as soil-cement, pozzolanic concrete etc. are designed as semi-rigid pavements.

Subgrade and Subbase for Concrete Slabs

-
Image
Subgrade and Subbase are the foundation of a concrete slab and play critical role in its performance.  Subgrade for Concrete Slab This is essential for concrete slab because this concrete slab load and imposed loads are supported by subgrade. When required, this concrete slab can be placed on the top of natural soil. Concrete slab can be made by using Sanghi Cement, Sanghi OPC 53 Grade cement, Sanghi PPC cement, Sanghi Ready mix concrete. Sanghi is the major cement suppliers in Gujarat also the ready mix concrete manufacturer. Concrete slab does not need any extra layers as it is clean and compacted. If soil is wet due to rain or any other reason than it cannot be compacted and suitable grade cannot be obtained. The organic soil is the least desirable because it cannot be consolidated and hence shall be removed from the site. All type of soils need improvement and this can be done by compaction and stabilization. Stabilization can be done by Ordinary Portl

Techniques of Soil Improvement

-

Soilimprovement is to improve its engineering performance such as strength, reduced compressibility, reduced permeability, or improved ground water condition. There are various techniques used for the improvement of the soil based on the construction activity and type of soil. The soil improvement techniques are the following. Ø   Surface Compaction: This is process to make soil densify. Any soft and loose site needs a compacted base for lying the structure. All conventional rollers like smooth wheel, rubber-tyred, sheep foot, vibratory and grid rollers can be used. Ø   Drainage Methods: When the water presence increase that will create pore water pressure and decrease the shear strength so ground water has to be controlled. Heavy inflow of water can cause erosion. So certain methods will have to be adopted to control ground water. Ø   Vibration Methods: Vibration methods can be effectively used for rapid densification of saturated non-cohesive soils.Some of t

Vacuum Concrete

When hardening of concrete takes place excess water should be removed otherwise it will reduce concrete strength. So Vacuum concrete the type of concrete in which the excess water is removed for improving concrete strength. The water is removed by use of vacuum mats connected to a vacuum pump. Water cement ratio is important to achieve higher strength and Workability is also important for concrete, so it can be placed in the formwork easily without honeycombing. When Workability requirement is over this excess water will evaporate and leave capillary pores in the concrete and that leads to into high permeability and less strength in the concrete. Therefore, workability and high strength don’t go together as their requirements are contradictory to each other. This technique is such way unique that it can provide to fulfil these two requirement at the same time. This technique is used in industrial floors, parking lots and deck slabs of bridges  etc.  This can be done
