FDOT Asphalt Paving Level 1 Practice Test

When the temperature of an asphalt mix deviates from the established specification by more than 25°F, it is subject to rejection. This is pertinent because the performance of the asphalt mix is closely tied to its temperature during application. Variations outside of the specified temperature range can lead to inadequate bonding, improper compaction, and compromised durability of the pavement. A mix that is too hot may lead to excessive oxidation of the binder, while a mix that is too cold may not compact properly, resulting in weak pavement structure. Therefore, maintaining proper temperature is crucial for the integrity of the asphalt paving process, and any significant deviation necessitates rejection to ensure quality and performance standards are upheld.
