Portions of the Department's highway drainage system design have recently been revised. Essentially, the longitudinal drainage trench was moved closer to the pavement/shoulder joint, and the fine concrete sand layer was eliminated as a trench backfill material. The specified backfill material is the coarser PA No. 1B crushed aggregate (pea gravel). This report deals with the evaluation of the effects of these changes on pavement performance and compares the new pavement base drain system to the older pipe foundation underdrain system at the same site.
