This guideline document is prepared to guide pavement maintenance personnel in the selection, installation, and evaluation of materials for hot-poured crack sealant treatments for flexible pavements. The information provided in this guideline is based on the field performance of 17 conventional sealants installed at five different sites in North America as part of the FHWA TPF-5 (225) pooled fund study: “Validation of Hot-Poured Crack Sealant Performance Based Guidelines”.

The document covers the following phases:

- Planning and design considerations;

- Treatment and sealant selection;

- Installation equipment and procedures.
