COMPARISON OF PAVEMENT DRAINAGE SYSTEMS. FINAL REPORT

Pavement drainage systems have become a common addition to construction and reconstruction plans. Several types of transverse and longitudinal drains that vary in shape, size and cost are often included in designs although little is known about their performance. This study describes and evaluates the drainage characteristics and pavement performance of four drainage systems under jointed portland cement concrete pavement. Included are the Minnesota Department of Transportation (Mn/DOT) standard dense graded base, two dense graded base sections incorporating transverse drains placed under the transverse joints, and permeable asphalt stabilized base, a design which reflects current Mn/DOT drainable base thinking. All sections include longitudinal edge drains. Construction of the test sections was done during 1989. Monitoring of rainfall and drainage began in 1990 and continued through 1994. Experiment variables include drainage flows, percent of rainfall drained, time to drain, base and subgrade moisture content, and pavement and joint durability. Pavement performance evaluations will continue over the next several years. This paper presents an overview of the study, examines the data, and summarizes the findings. The study is expected to lead to improvements in the design of positive pavement drainage systems.
