INTRODUCTION
Soil stabilization is the process to improve the engineering properties of poor soils as well as enhancing good soils to meet specified requirements and reduce the construction time. Soil Cement is the simply method to improve the engineering properties of the raw soil by
using high-compacted mixture of soil, Portland cement, and water so that the mixture gains strength and durability rapidly. Soil cement technology first developed in the USA in 1935 for highway construction. This technology gains its worldwide popularity rapidly with the
fields of application in developed countries. The purpose is for road construction which resulting in increased bearing capacity of soft subgrade, enabling a reduction in the thickness of the base course. However, Soil cement also generates the advantages such as
need to follow the standard strictly, water can penetrate if capillary void too big, less flexibility, and it is not suitable for some type of soils.
​
Polymer Chemroad is polymer based mixture of latex and cellulose dispersed in water. It is formulated to stabilize the cement and in-situ soils with water for an ideal and high quality concrete-like road base which will make road building much cheaper and faster than
conventional methods. Polymer Chemroad worked by compacting and curing a mixture of soil/aggregate Portland cement, Polymer Chemroad and water to form a handle. Polymer Chemroad help the process of building soil cement to be more perfectly. It improved the
bonding efficiency of the cement to minimize the micro crack in the soil cement and modulus of elasticity created the properties of flexibility and water proof in the mixture. Chemroad structure is able to use the in-situ soil on the spot mixed with cement and polymer Chemroad for construction of the better road base, no expenses for those extra materials such as small stone, no delivery charge, save both time and money.
Advantages of Polymer Chemroad
Some of the major advantages when apply Polymer Chemroad are :
-
Minimal quantity of stabilizer used, and the making use of existing soil are all contributed towards economy saving.
-
Simple, neat and efficient construction method method means good time saving.
-
Choice on construction equipment to suit circumstances is possible.
-
Stabilized pavement structure increase strength with time and give better performance through time.
-
Making use of existing soil material will lessen dependence on quarry products from outside. This would mean resource conservation and a sustainable development.
-
Non-toxicity coupled with factor in (v) mean an environmentally friendly approach.
-
Polymer in the stabilizer enhances the Modulus of Elasticity (M.O.E.) and durability offer good resistance to repeated load usually applied to road pavement.
-
Once cured and hardened the pavement sub-layers are least susceptible to water and therefore becomes dimensionally stable , an important performance criteria
-
Good construction track records prove technical soundness of the method.
Q : What is Polymer Chemroad?
A : Polymer Chemroad is polymer based mixture of latex and cellulose dispersed in water.It is polymer base mixture of latex and cellulose dispersed in water. It is formulated to stabilize the cement and in-situ soils with water for an ideal and high quality concrete-like road base which will make road building much cheaper and faster than conventional methods. Various mixing methods can be used depending on site conditions and the utility requirement. They mayrange from manual mixing. using of grader. and the particular mixer.
Q : How polymer chemroad works?
A :Soil cement–defines as materials produced by blending. Compacting and curing a mixture of soil/aggregate Poetland cement, polymer chemroad and water to form a handle, materials with special engineering properties. While polymer chemroad additive improved the bonding efficiency of the cement to minimize the micro crack in the soil cement and modulus of elasticity created the properties of flexibility and water proof in the mixture.
​
Q : Why use polymer chemroad with Soil-Cement?
A : Polymer chemroad help the process of building soil Cement to be more perfectly. It gives safety in terms of durability because of its properties that help soil cement process give more economically in building road. So, there will be very much more different in soil cement with polymer chemroad and soil cement without polymer chemroad.
​
Q : Why use polymer chemroad with Soil-Cement?
Q : What type of cement required to use with Polymer chemroad?
A : Portland Cement type I or type II that conforming to ASTM C150 is suitable for using with polymer chemroad.
​
Q : Can polymer chemroad be used without Cement?
A : Polymer chemroad was designed only to use with cement. It’s invented to enhance the bonding of cement treated soil. Polymer chemroad is mixed to the soil with measured amount of Portland cement and water compacted to a high density. When the cement hydrates it’ll uniform a strong, durable slab-like material base. Shrinkage cracking occurring by nature of soil-cement is solved. At this point polymer chemroad appears to better control cracks and water penetration into those cracks. The pavement and the road base will be durable.
Q : Can polymer chemroad be applied to all type of soil?
A : All types of soil can be used except the organic soils. Granular soils are preferred in terms of easily pulverizing and mixing as a result of economically. The different types of soils need the different amount of polymer chemroad mixture.
