6-Attachment I - Thermal Crack Repair Detail (Heavy Duty - 5.0 Wide).pdf

This is a technical specification attachment for the City of Wichita's 2026 Outsourced Pavement Preservation Program CIP Microsurfacing and Street Repair project in Kansas. The document provides detailed instructions for thermal crack repair procedures, specifically outlining the standard and heavy-duty applications for both 2.5-foot and 5.0-foot wide repair sections. The specification requires placing 2.5 inches of BM2 64-22 material with approved knitted fiberglass reinforcement over milled thermal cracks. The process involves milling the thermal crack surface, tacking the milled surface, and leveling the material with millings, sand, or asphalt concrete to create an even surface for fiberglass placement. Both standard and heavy-duty configurations are detailed with identical width options of 30 or 60 inches, with instructions to leave sufficient material in the thermal crack to provide proper level support for the reinforcement layer.

The document serves as a technical guide for contractors bidding on pavement preservation work and does not contain pricing information, set-asides, contract term details, or funding sources. This attachment is one component of the broader specifications package for the street repair project and establishes the materials and construction methodology that winning bidders must follow for thermal crack repair work.
