PATCHING CREW

A maintenance and patching crew consisting of a dump truck and three men is required for approximately each 100 kilometers of road, to repair local defects which may show up before application of the second armor coat. This crew also places rock riprap at culvert locations, to protect against water erosion.

SECOND ARMOR COAT AND TRAFFIC AIDS

The second armor coat will follow approximately twelve months after the first armor coat, to give an opportunity for traffic to expose any defects in the surface or sub-grade, and for such defects to be repaired. Application of the second armor coat is identical with that of the first. Traffic aids are then installed. These consist of a center line stripe of yellow paint, special striping to warn against passing where sight distances are limited, curve markers for visual guidance, and warning, precautionary, and information signs where needed.
