Geocell road construction is a method that uses geocells, beehive-like structures made from polymer materials like high-density polyethylene (PEHD), to strengthen and stabilize roads. These structures resemble a grid and are usually deployed in flexible or unstable ground conditions.
Here’s how geo-cells are used in road construction:
Site Preparation: The first step is to prepare the site by removing vegetation, leveling the surface and addressing any drainage issues.
Geocell Installation: The geocells are then folded and fixed to the ground using staples, pins, or other mechanisms. The specific installation method depends on the type of geocell and project requirements.
Fill placement: Empty spaces inside geocells are filled with various materials such as gravel, crushed rock, sand or even concrete, depending on the desired application and traffic load.
Compact: The filler material is compact to create a stable and uniform base for road paving.
Paving (optional): In some cases, an extra layer of asphalt or concrete may be applied to the compact filler for a more durable, finished road surface.
Advantages of using geo cells in road construction:
Soil stabilization: geocells prevent the lateral movement of soil particles, thus increasing the stability and the bearing capacity of the roadbed. This is especially beneficial on soft or weak floors.
Erosion Control: Geocell’s beehive structure helps hold soil and prevent erosion, especially on slopes and fillings
Reducing construction costs: Geocells can often reduce the need for expensive excavation and soil replacement, resulting in lower construction costs.
Increasing Road Lifespan: By mitigating soil movement and erosion, geocells can extend the lifespan of roads and reduce the need for maintenance.
Environmental Benefits: Geocells can help minimize the environmental impact of road construction by reducing the need for excavation and resource consumption.
Geocell road construction is a versatile and efficient technique that can be used in a variety of applications, including:
New road construction: Geocells can be used to create stable, durable roads on soft or unstable soil.
Road Rehabilitation: Geocells can be used to repair and strengthen existing roads that show signs of distress.
Unpaved Roads: Geocells can be used to create strong, durable unpaved roads for access roads, parking lots, and other applications.
Slopes and infills: Geocells can be used to stabilize slopes and infills along roads and highways.
If you’re considering using geocells for your next road construction project, be sure to consult with a qualified engineer or contractor to determine the best geocell type and installation method for your needs.
