Gravel Roads Asset Management

In the winter of 2004, the Wyoming Technology Transfer Center in cooperation with the Wyoming Department of Transportation and Sheridan, Johnson, and Carbon Counties of Wyoming undertook a 3-year project to institute a geographic information system- (GIS-) based asset management program. It encompasses inventorying, rating, and optimization strategies for improved gravel roads, as well as for the limited mileage of asphalt and unimproved roads in the counties. The roughly 2,000 mi of roads in the three counties were located with a Global Positioning Satellite system and rated using the Wisconsin Transportation Information Center’s Pavement Surface Evaluation and Ratings manuals, modified for Wyoming’s conditions. In addition, expenditures on each road section are tracked through maintainers’ daily reports. Signs, sign supports, cattleguards, approaches, and culverts were rated and located. Bridges were located. Interviews with maintainers were conducted to gather historical and routine maintenance information on each section. This report describes the current status of this asset management program and road surface management system. The goals of this program are two-fold, similar to those in widespread use for asphalt and concrete roads. First, it is to be used on a network level for financial and management decisions and strategies. Second, at the project level, it is to be used to make specific maintenance and construction recommendations on individual roads, largely through a life-cycle costing approach. Off-the-shelf GIS software is used to enter and manipulate the data collected. Adapting this software to surface management tasks was relatively simple, given the user-friendliness of the newer GIS packages. Recent modifications allow for multiple entries for a single feature. Cost estimates for routine activities, such as mowing, snowplowing, and reshaping gravel roads, allow the counties to make reasonable, detailed estimates of the cost of maintaining gravel roads under different conditions. For these and numerous other applications, the asset management system is streamlining county operations.
