Ultra-thin concrete overlay supports truck loads
By mid-July 1992, the overlay had been exposed to the continual pound- ing of truck loads for 43 weeks. The esti- mated equivalent 18,000-pound axle loads (E-18s) the overlay has experienced is near 475,000. As a comparison, low- volume roads, city streets, and parking lots typically are designed to carry 50,000 to 100,000 E-18s.

The resulting concrete is known as ultra-high strength concrete [121], [122], and it is distinguished for its great durability, self-compactability, and high strength. The concept of UHPC was first introduced by Larrard in 1994 [123]. UHPC is a novel type of concrete recently developed for its superior strength and durability (Fig. 6) [124], [125].

TechBrief: Thin Concrete Overlays
Concrete overlays less than 6 inches (152 mm) thick are commonly identified as "thin" concrete overlays, while the term "ultra thin" is sometimes used to refer to overlays less than 4 inches (102 mm) thick. These thin overlays also feature smaller slab sizes, with 6 ft by 6 ft (1.8 by 1.8 m) panels commonly used.
