DRAINAGE PRACTICES IN THE NORTHEASTERN STATES
This paper compares the practices of the Northeastern states--Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, and New Jersey--with regard to drainage. Problems in the Northeast have been primarily paving problems on fills. A brief summary of eight drainage items in the Northeast is presented: compaction of the filter material is required in practically all cases; perforations are placed both up and down; underdrains are located anywhere from the edge of the pavement, to beyond the edge of the shoulder; it is difficult to identify whether the primary purpose of a typical section is to control groundwater or act as an underdrain for the pavement section; it is, perhaps, expected that a drain is supposed to serve both functions and that the two separate problems are not recognized to exist; it appears that virtually every state is sealing-off the underdrain with their first layer of subbase; only one state has a program of maintaining underdrain systems by flushing them on a routine bases; and it is seldom that rational design is used in the design of a drainage system.
