Construction loading of slab-on-grade
Construction loading of slab-on-grade
(OP)
To finish a combination asphalt and concrete road network, the contractor wants to use a construction process which slipforms the curbing first, then places the 10-inch thick reinforced concrete turnpads at intersections, followed by the asphalt paving between the concrete turnpads. Question is how long should the contractor wait before placing construction loads of the paver and loaded asphalt trucks on the concrete turnpads. f'c = 4,000-psi with #3 bar both ways at 12-inches O.C. Your perspectives please!

- Allowable soil bearing capacity = 3,000 psf
- Minimum 24-inch thick subgrade compacted to 95% modified proctor for both asphalt and concrete areas.
- 4 1/2-inch thick base course of 2A modified (well-graded crushed stone) aggregate compacted to 95% modified proctor for concrete areas.
Turnpads and roads were designed for traffic loads of military vehicles up to 70 tons.
