摘要

A study of increasing the thickness of a single-lift of Aggregate Base Course (ABC) has been carried out at two project sites. This report presents the results obtained by the North Carolina Department of Transportation (NCDOT) from testing the increased single-lift ABC. All site preparation, compaction operations, and testing methods were performed in accordance with the 1990 edition of NCDOT Standard Specifications for Roads and Structures. The data gathered from both test sites was satisfactory when compared to NCDOT minimum specification requirements. The NCDOT currently allows the contractor to have the option of a maximum of ten inches of ABC compacted in a single-lift.
