Roadstab technology is a Russian innovation since 1996, specializing in road stabilization and cold reconstruction using a concentrated liquid stabilizer that enhances the structural integrity of roads. The technology offers various advantages including reduced material costs, immediate traffic usability after compaction, and effective performance under challenging conditions such as heavy moisture and temperature fluctuations. Project implementations demonstrate significant cost savings and improved durability compared to conventional road construction methods.

RoadstaB

2. Introduction
RoadstaB Technology is tested Russian Technology since 1996.
Our Group is specialized in innovations in Road industry. Our main verticals are as
following:
Road Stabilization: (not soil stabilization)
RoadstaB organic compound is a concentrated liquid stabilizer, which helps in reducing
frictional resistance of molecules while compaction, and creation of flexible crystal
between molecules to bind them together while not loosing its flexible properties and
formation Of monolithic load bearing structure.
Cold Reconstruction: Uses and milling of old asphalt with base layer and mixing it with
RoadstaB compound for formation of base. In this technology only upper wearing course
shall be provided, old structural layers shall be reused.
Plastic Armature: This is a substitute of steel armature with enhanced performance and
Strength properties like 1200-1800 Mpa, and advantages of lifetime rust proof, deduction
Of 90% transportation cost.

24. Mountains Roads
Mountain Road construction is always difficult due to
space, and requirement for area in construction
process.
• No Curing: RoadstaB Stabilized road doesn’t require
curing. It can immediately open to ply traffic after
compaction. This would solve the continuous traffic
problem and Traffic jams while construction.
• High Altitude area: RoadstaB layer can with stand
heavy moisture and freeze and thaw cycles, since the
layer is impermeable and doesn’t let moisture to
perforate to base layers to keep the subgrade dry
and safe.
• Less inert material is required and can be
constructed with Insitu material, which increases the
construction speed and decreases the material
transportation.

25. • Road Crust in Monsoon Season Showing
impermeability of RoadstaB Layer,
which serves as load bearing and
separation function of structure.
• Less crust thickness: It decreases the
crust thickness due to its load bearing
capacity, which results in deduction of
material layer thickness.
• Durable and safe Roads: Even after the
completion of life cycle of Asphalt
layer and cracks of it, pot hole doesn’t
appear on the surface. Monolithic
RoadstaB layer plays the road surface
role and provides Safety.
