OPTIMIZATION OF PAVEMENT REHABILITATION AND MAINTENANCE BY USE OF INTEGER PROGRAMMING

An integer programming technique has been used to develop an operating computer program called RAMS, which determine optimal maintenance strategies for pavements by maximizing the overall maintenance effectiveness for all highway segments considered. The program can use numerous maintenance strategies, resources, and feasibility constraints to obtain solutions. An example problem that contains actual field data on 15 highway segments located in one Texas highway district was used to demonstrate typical program input and output. This example revealed that, for 9 of the 15 pavement segments studied, maintenance strategies selected by the computer program were essentially identical to those selected by district personnel of the Texas State Department of Highways and Public Transportation. Both RAMS cases presented are optimal with respect to department selections. /Author/
