Tex-423-a Patched

Insert a depth rule perpendicular to the surface until it reaches the bottom of the cut.

For decades, engineers battled a phenomenon known as stripping. This occurs when water infiltrates the asphalt binder—the glue that holds the aggregate rocks together—and separates the two. The result is a loss of strength, leading to raveling (loose rocks), potholes, and eventually, total pavement failure. tex-423-a

A straight, smooth steel or high-density plastic rod (typically 5/8-inch diameter) with hemispherical tips. Insert a depth rule perpendicular to the surface

Position the steel rod normal (perpendicular) to the pavement surface. Insert it through the fresh concrete until it reaches the full depth of the pavement. leading to raveling (loose rocks)
