Abstract:The objective of this research project was to determine where, when, and why a prime or cure is needed for a pavement layer. Materials such as prime coats, curing materials, seal coats, and tack coats are typically considered nonstructural but integral to the pavement structure. Some materials can be used for multiple purposes, such as to prime, bond, or help cure; however, the rates and timing of use may change depending on why the material is being used. To aid decision-makers in determining whether a prime, cure, or bond material is needed, guidance was developed. Recommendations for where, when, and why to design and use the prime materials were developed.
