This paper examines the design of pavement drainage systems from the perspective of the contractor. From an economic standpoint, it is still not certain what an effective underdrain system is composed of and how much it costs. Many overlay jobs simply delay a pavement water problem a little longer--until the next overlay--instead of solving the water problem underneath the pavement. One serious decision to be made in the design of an edge drain is the location of the drain with respect to the edge of the pavement. For an underdrain system, designers must decide whether to put the underdrain system in through the stabilized and granular bases and then pave over the top or to pave it and then come back and put the underdrain system in. Government agencies involved in design approval should scrutinize drainage design plans and specifications carefully. Two distinct problems face those involved in pavement drainage: the design of new pavements, and the elimination of water problems on existing pavements. The paper contains descriptions of 24 slides that illustrate some of the problems faced by drainage contractors, along with construction practices that may offer some solutions. Topics addressed include edge pumping, asphalt shoulder pumping, shoulder maintenance and rehabilitation, longitudinal underdrain placement, placing the first course of granular material, clay pipe installation, placing the second course of backfill, construction of a portland cement concrete shoulder on an existing pavement, shoulder joints and rumble strips, slip-form concrete shoulder installation, tying pavement joints, random skewed joint spacing, and fibrous concrete.
