Value Engineered Solutions ® for Soil Stabilization, Erosion Control & Sustainable Dust Control

LTWP- Phase 1

The Lake Turkana Wind Power project is located in Loiyangalani District, Marsabit County, Kenya. It comprises of 365 wind turbines, each with a capacity of 850kW, and a high voltage substation that will be connected to the Kenyan national grid through an associated Transmission Line.

The wind farm is ready to provide 310MW of reliable, low cost and green energy that will power one million Kenyan homes.

Having already invested a significant amount in the initial road construction required to transport the 365 wind turbines throughout the 250 km wind farm, the roads now require an upgrade. In total 1095 blades spanning 55m and 365 towers measuring 36m travelled the gravel roads.

LTWP contacted Soil Solutions for a cost effective and sustainable solution.  Soil Solutions conducted a site assessment and then developed a long term cost effective sustainable solution that will protect the initial capital infrastructure investment and allow for a much improved road network, while reducing required future maintenance.  This includes the integration of Engineered Base Stabilizer  (EBS) to stabilize and surface seal the initial 50 km section of the road network.  This will allow for a hard surface fully protected from any erosion or material lost.  This will also eliminate any wind or vehicle generated dust and increase the efficiency of the turbines. To ensure that the project is concluded in a cost effective and efficient manner a RSL Recycler Machine was also recommended for the project.

 

Application: The existing surface is ripped, scarified or recycled, then shaped to provide proper drainage, compacted to a smooth finish then sealed with the EBS Soil Stabilizer in multiple coats until the point of refusal is reached. The EBS is allowed to penetrate then the road is opened for traffic.

 

Result:a re-constructed surface layer with a newly created wearing course with complete dust elimination, improved skid resistance, total preservation of fines and material, is non-slippery, water and UV resistant, free from the formation of potholes, rutting and corrugation, improved load bearing capacity, increased tensile strength and a reduced environmental impact.

 

THE EBS SURFACE SEALED ROAD SURFACE IS NEVER TO BE GRADED OR WATERED … The objective of the EBS Surface Seal is to eliminate the requirement for any future watering or grading of the surface.

 

After 18 months (or when required) the surface may need a maintenance application of EBS at a reduced application rate.
