Base Course Reinforcement
Base course reinforcement involves using geosynthetics to improve the load-bearing capacity and stability of soil bases. These geosynthetics are typically grids or mats made of high-strength polymers.
When placed within the base course, geosynthetics act in a few ways to reinforce the soil:
Lateral restraint
They confine the soil particles, preventing them from spreading outwards under load. This helps to maintain the shape of the base course and reduces the risk of rutting.
Improved bearing capacity
Geosynthetics distribute traffic loads more evenly over a wider area, reducing pressure on the underlying soil. This can be especially beneficial on weak subgrades.
Separation of layers
Geosynthetics can prevent the intermixing of different soil layers, which can compromise the overall strength of the base course.
Base course reinforcement is commonly used in various applications, including:
- Road construction
- Slope stabilization
- Embankment reinforcement
- Retaining walls
