Slab on Grade for Airports
High-performance post-tensioned slabs for airports
Slab on Grade is a high-performance pavement system using post-tensioned concrete technology to create large, joint-free slabs. Designed to withstand heavy rolling loads and intensive operational use, this solution is particularly well suited for airport aprons, parking areas, and logistic platforms.
Why using a Slab on Grade in airport zones
Optimized post-tensioned design reduces slab thickness while maintaining structural performance, resulting in lower material consumption and improved construction efficiency.
Large, continuous slab panels minimize joint deterioration and significantly decrease long-term repair requirements in high-traffic airport environments.
Post-tensioning improves stress distribution and controls shrinkage, reducing the formation of cracks and surface defects over the slab’s service life.
The system is engineered to withstand repeated aircraft gear loads, ensuring reliable performance under both stationary and rolling stresses.
Lower concrete volumes directly decrease the embodied carbon of the pavement system, supporting airport sustainability objectives.
The PT slab system can be combined with tailored ground improvement solutions to deliver stability and uniform performance on variable or low-quality soils.
