This study evaluates the performance of slotted plastic underdrains under full-scale dynamic loadings. Two types of slotted plastic pipe, polyvinyl chloride (PVC) and polyetheylene (PE), were studied under moving wheel loads in the WES circular test track facility. The pipes, buried at 6, 12, and 18 in. (15.24, 30.48, and 47.72 cm) below a double-bituminous surface treatment pavement, were instrumented to measure vertical and horizontal deformations under both static and dynamic loads. Conventional corrugated metal pipes were used as a standard for comparing the pipe performance. Results indicated that both PVC and PE underdrain pipe performed satisfactorily if the filter material was compacted and a minimum burial depth of 12 in. (30.48 cm) for PVC and 18 in. (47.72 cm) for Pe was maintained. /FHWA/
