• Abstract:
  Impact hammer compaction has historically been used to develop moisture-density curves and fabricate specimens for strength testing for flexible base and subgrade materials. But the impact hammer compaction’s precision of compressive strength can cause conflicting test results about whether a material meets specification requirements. This project used the Superpave gyratory compactor (SGC) to analyze if SGC compaction improves the precision of compressive strength tests for flexible base and subgrade materials, and analyzed a procedure for determining the moisture-density curve of base and subgrade materials using the SGC. Also, researchers evaluated the applicability of SGC for base materials in mechanistic-empirical (M-E) pavement design methods.
