The purpose of Phase II of REREPS repair and restoration of paved surfaces is to evaluate previously developed techniques and materials and to conduct necessary studies to determine the most beneficial backfill material. The study is to include new materials and innovative methodology to the greatest practicable extent. Compaction requirements are to be analyzed by comparison with existing requirements as modified by REREPS results to date. Specific compaction requirements include a quantification of compaction requirements versus depth below the load as well as subgrade compaction versus pavement strength and stiffness. Another specific requirement is to study the applicability of the sand grid support concept. In addition, other new methods and materials will be reviewed, developed, andor introduced, as appropriate. This study constitutes partial completion of these objectives. An investigation research effort has been made to review the status of REREPS development to data.
