The cracks occur directly over the underlying cracks or joints. "Joint reflection cracking" specifically refers to reflection cracks arising from underlying PCC pavement joint movement. Reflection cracks can also occur over existing HMA pavement cracks, cement or lime stabilized base, etc. Figure 1: Joint reflection cracking on an arterial.
The investigations conducted in North Carolina University have demonstrated that a special type of continuous fiber-mat HPFRCC, called SIMCON which stands for Slurry Infiltrated Mat Concrete, is well suited for the development of novel repair, retrofit and new-construction solutions that lead to economical and improved structural performance.

Solutions for Chapter 11 Problem 61E: In a discussion of the article "Tensile Behavior of Slurry Infiltrated Mat Concrete (SIMCON)" (AC/ Materials J., 1998: 77-79), the discussant presented data on y = toughness (psi) and x = aspect ratio. He stated that "a (simple lineal) regression analysis clearly shows that the aspect ratio is not a reliable variable that can be used to predict toughness."
SIMCON is made by infiltrated preplaced continuous steel fiber mats with a cement-based slurry. Due to its fiber-mat configuration, 1) individual fibers have very high-fiber aspect ratio, leading to a significant increase in strength, ductility, and toughness; and 2) fiber mats are delivered in prepacked rolls that can be easily cut and handled ...

IMPROVED CONCRETE OVERLAY CONSTRUCTION Abstract of the Disclosure Crack and wear resistant concrete overlays for renovation or patching of deteriorated sections over a substratum can be made by incorporating 4-12 volume per-cent steel fibers in the concrete overlay and bonding at least a portion of the fibers directly to the substratum.
Mat Concrete (SIMCON) can be produced. SIMCON is made using a non - woven "steel fiber mats" that are infiltrated with concrete slurry. Steel fibers produced directly from molten metal using a chilled wheel concept are interwoven into a 0.5 to 2 inches thick mat. This mat is then rolled and coiled into weights and sizes convenient to a ...
