HIGHWAY SUBDRAINAGE DESIGN BY MICROCOMPUTER: (DAMP) DRAINAGE ANALYSIS AND MODELING PROGRAMS (VERSION 1.1). FINAL REPORT

This report presents the user's manual and technical guide for a software program named DAMP (Drainage Analysis and Modeling Programs), designed to perform drainage design for highways by microcomputer. This program includes a comprehensive examination of the drainage factors which affect pavement design and performance. The following modules are included: a) determination of net inflow by surface infiltration, ice lensing, and an evaluation of pavement geometry affecting outflow of water, b) determination of the AASHTO drainage coefficients using base drainage times, and climatic saturation moisture exposure calculations, c) an edge drain analysis of pipe drains, geocomposite fin drains, and granular trenches, d) drainage layer analysis using calculated permeability and thicknesses, and e) filtration analysis using granular material gradations and filter fabric evaluation. These calculation modules have been programmed into a user interactive program which allows the user to use any module independently of the others to perform sensitivity analyses. Context sensitive help is provided and graphical help screens are included where necessary. The program has the ability to perform batch calculations and print results directly to a disk file or a printer.
