StabilRoad

STABILROAD^® IS STABLE AND DURABLE!

Modern civil engineering has been using cement as the main stabilizer due to its excellent bonding properties. But this does not work on clay, sandy and muddy soil. In such cases, besides better bonding, fill surfaces should be used. The problem with this is that the cement-treated soils become very rigid and the risk of surface cracking is very high.

By using the StabilRoad® cement additive in a corresponding amount along with prescribed proportion of cement, there will be no risk of cracking. This is due to its ability to change the parameters of the concrete’s bending strength. StabilRoad® is today one of the most advanced and technologically innovative soil stabilization material and technology in the world.

StabilRoad® is a whitish powder made of 100% natural minerals with no synthetic chemicals. STABILROAD® technology has been developed in Germany and has been used since 20 years in most of the world’s diffrent climate zones.

Traditional Road Construction vs StabilRoad^®

STABILROAD^® IS STABLE AND DURABLE!

The most important feature of this technology is that by using the StabilRoad^® additive and special technology we can significantly accelerate the construction process, reduce the cost of work, and at the same time achieve a very strong, elastic, waterproof and frost-proof surface. All this can be achieved by reusing existing road and local soil. The treated surface can be put into operation just in few hours, after the necessary work is completed. Stabilizing with StabilRoad^® technology entails the mixing together of existing soil (including old asphalt), StabilRoad^® and cement (Portland cement needed, clinker content> 95%) is mixed together. The StabilRoad^® additive increases the process of cement hydration, in which cement particles form a reactive water by reacting new bonded compounds, which consists of a concrete skeleton. As a result of crystallisation, water-insoluble compounds are formed which make the treated layer non-water-absorbing. Increasing the cement hydration will reduce the amount of cracks caused by volume reduction, increasing the elasticity of the stabilized surface, compression and tensile strength, and the material becomes cold and waterproof. The stabilized surface can be compared with concrete in its properties. Stabilizing with StabilRoad^® is used instead of substrata and frost protection layers. By using StabilRoad^® , each treated layer can also work as the top layer of the coating on low-traffic roads. Depending on the field of application, a protective layer of asphalt may be necessary as a final layer, for example by coating or asphalting. StabilRoad^® technology was first used in India in August, 2017 at M/S Krishnapatnam Port Company Limited. STABILROAD^® INDIA has executed close to 6 kilometres in Krishnapatnam port and close to 5 kilometres in the city of Hyderabad, close to 3 kilometres in Vijayawada, Andhra Pradesh and 6 Kilometres in Kerala with excellent results. Presently, we are in the process of constructing more roads in Andhra Pradesh, Kerala, Maharashtra and Punjab using this technology.

EXECUTION PROCEDURE

In-situ Stabilization of upto 50 cm thick, filled up embankment soil of CBR value > 5% , P.I < 20% by cold in-situ recycling using cement and stabiliser (additive) of required quantity as per design mix.123
Cement is spread on the embankment soil using a mobile truck mounted Containerized Cement Spreader with Microprocessor-controlled Weighing and Spreading mechanism.
Additive of desired quantity is spread over with tractor mounted Containerized Additive Spreader.
The in-situ stabilization for the desired depth is carried out by a Mechanized Recycler.
The resultant pulverized mix is compacted using a 20 ton Pad Foot Roller and profiled to the required grade, level and thickness using a Grader and rolled with a Smooth Wheel 8-10 ton Tandem Vibratory Roller and Pneumatic Tyre Roller to achieve a Field Density of > 98%.
The process is completed with curing.
The pavement achieves an Unconfined Compressive Strength (UCS) value of 4.5 MPa in 28 days.

PRESERVING THE ENVIRONMENT

01 Km of a 2 – Lane, Rigid Pavement requires 5,719 Cum of Stone Aggregates and 2035 Cum of Sand.
01 Km of a 2 – Lane width Full Depth Recycled Pavement requires 843 Cum of Stone Aggregates (equivalent to 60 truck loads), if the traffic is > 20 MSA.
Adoption of Full Depth Recycling Technology instead of Conventional Rigid Pavement can preserve up-to 4876 Cum of Stone Aggregate and 2035 Cum of Sand, per km for a 2-Lane width road, which is equivalent to 494 Truck Loads.
About 40,000 Kms of highways have been constructed in the past 5 years.
Its performance has been validated by IRC, IITs, NITs etc…
Around 65,000 Kms of highways have been planned in the next 3 years. Going by this rate, another 1,50,000 Kms of Roads can be expected by 2028.
Total Stone Aggregate Requirement would be approx. 1094 Million Cum.
If at least 10% of the above roads i.e. 21,500 Kms were executed using this technology, then about 109 Million Cum of Stone Aggregate can be preserved, which is equivalent to 78,26,000 Truck Loads. This is based on the assumption of a 2 – Lane Road.
This is a rough indicator of saving of Natural Resources in the Country. Click here to Read More.
