TRANSCRIPT
Additives to stabilize and solidifies soil (stabilization & solidification)by means of Physics-Chemistry.
Form : powder composed of inorganic minerals.
ROTEC is developed and testedIn sub-tropical climates.
Water coated soil particlesare NOT able to stick maximally with cement.
Soil Condition
ROTEC fill the cavities of soil particles, causing cement to attach perfectly.
Role of ROTEC
Soil
Soil particlescoated with water

ROTECdecomposes water in the soil
Soil blends perfectly with cement
Soil particles are coated with ROTEC

Transportation Soil Foundation Etc
• In road construction, as a
substitute of LPA & LPB CBR up to 285%.
• Base course for airstrip, parking area, railroad, helipad, etc.
• Road construction for mining & plantation.
• Improves peat soil & expansive soil.
• Substitutes vertical drain method in soil compression.
• Strengthens cliffs to prevent landslides.
• Dam construction material (clay substitution)
• Waterproof coating (k= 10-7 cm/s)
• Dust pollution prevention
• As a matrix that binds poisonous and dangerous substances.
Application
Hotmix 5cm
LPA 20cm
LPB 30cm
Conventional Construction
• LPA CBR 50%
• LPB CBR 20%
• Expensive• Weak
ROTEC proved superior in terms of quality, cost and time
Hotmix 3cm
ROTEC 20cm
• CBR up to 285%• Cost-efficient• Strong
ROTEC Construction
Road ConstructionComparison
• Soil bearing capacity increases• CBR > 100%• Strong (Micro particles bond)• Waterproof (prevents bumpy road)• Directly coated with concrete, alphalt, hotmix• Cheap• Road is getting stronger when exposed to water• Dust control (No Dust)
ROTEC Road Conventional Road
• Soil bearing capacity does not increase• LPB CBR 50%, LPA CBR 80%• Weak (Stone bond)• Non waterproof (Bumpy road)• Concrete coating needs
frame• Expensive• Road is getting weaker when exposed to water• Dusty road
Benefits

* Cement depends on the type of soil
** Water for ROTEC solution should be in optimal moisture level

Before Construction
Differences between before and afterROTEC construction
The more submerged the ROTEC road,the stronger it will be (after curing time).
