Implication

Randomized trial evaluates compaction uniformity in epoxy asphalt pavements, suggesting improvements in bridge deck construction.

Key Points

To assess the compaction homogeneity of epoxy asphalt pavements on steel bridges using nondestructive methods.
Evaluated compaction uniformity using PQI-380 density profiling on both layers of epoxy asphalt.
Generated air void maps to identify areas of inadequate compaction rapidly across bridge decks.
Measured compaction using mean, standard deviation, and coefficient of variation values for air voids.
Regions with air void content over 3% were deemed noncompliant and at risk for water damage.
Higher CV values (>24%) indicated poor compaction uniformity and potential segregation in the mixture.
Compliance rates for adequate compaction varied between 68.8% and 97.5% across different bridge segments.
