SUMMARY Proper compaction of unbound materials is one of the most critical components in the construction of pavements, airfields, and embankments to ensure their adequate performance, durability, and stability. Currently, field density is used as an indicator to assess the quality of compaction and construction of those structures.

3 According to the survey results, the majority of DOTs are interested in implementing stiffness- and strength-based specifications for compaction control of unbound materials, yet few DOTs have developed such specifications. This was attributed mainly to the lack of trained personnel and funds, the need for new testing equipment, and the unfamiliarity of contractors with such specifications.
