We are excited to share the latest findings from our research collaboration with Queensland University of Technology (QUT), Smart Pavements Australian Research Collaboration (SPARC) Hub & Industry Partners. The findings reinforce the fact that geogrids work!
Furthermore, they can SAVE you time and money when building working platforms and permanent flexible pavements.
What are Geogrids?
Geogrids are a type of geosynthetic that is used to reinforce soil. They are made of high-strength plastic and have a grid-like structure. Geogrids work by interlocking with soil particles to provide lateral restraint to resist movement. This in turn increases shear stress resistance, which can improve the performance of a pavement.
Our Latest Research Findings
Our research has shown that geogrids can be used to effectively reinforce extremely weak subgrades. We have developed practical design charts that can be used to save road base materials for a flexible pavement structure using the Austroads CBR approach.
We have also identified knowledge gaps from previous studies and learned from literature reviews of proven field studies using geosynthetics for pavement design.
Benefits of Geogrids for Flexible Pavements
Geogrids have become increasingly popular in recent years because of the many benefits they offer, such as:
- The ability to interlock with soil particles to provide lateral restraint to resist movement, which in turn increases shear stress resistance.
- Enhancing the performance of unpaved or paved flexible pavement.
- Distributing loads more evenly, reducing the risk of rutting and bearing failure.
- Reducing the initial cost of construction by reducing the sub-base thickness required.
- Compliance with QLD MRTS 58 – Subgrade Reinforcement using Pavement Geosynthetics.
