This report describes a microcomputer system for analyzing the information collected by state forces in their annual network-level Pavement Evaluation System (PES). Included in the MICRO-PES are the following three subsystems: a) A one-year Maintenance and Rehabilitaition (M&R) estimation system, which contains a series of decision trees developed by experienced engineers from the Maintenance and Pavement Design Divisions. The trees relate pavement distress to the appropriate M&R strategy and have been developed for Flexible, Jointed and Continuously Reinforced Concrete Pavements; b) The RAMS-District Optimization Program which selects an optimum combination of projects within a fixed budget level. Optimization uses 0-1 Integer Programming techniques and uses maintenance effectiveness as an Objective Function; and c) A routine Maintenance Estimate system which permits estimates of type, amount and cost of routine maintenance requirements for any highway or network of highways. The software package requires an IBM-XT on AT or compatible microcomputer with at least a 1.2 MB floppy disc drive, a 10 MB hard disk, 640 KB or RAM, an EGA graphics adaptor, and a dot matrix printer.
