Abstract

As Pavement Management Systems become the primary tool by which agencies allocate the funds for pavement rehabilitation, the accuracy of data collected for these systems becomes paramount. Distress data play a significant role in such pavement evaluations and there are many different methods available for collecting these data, one of these being manual distress surveys. However, manual (visual) distress surveys have their limitations. Inaccuracies that arise in the manual accumulation and summarization of the distress data can limit or impair its use significantly. In this study the latest "electronic clipboard" technology was employed to create a computerized system that will store and summarize distress data automatically. Software was developed so that as a distress and its associated location are identified and drawn "electronically", pertinent information about the distress is stored in a data base that is used to automatically summarize the results. Using this system greatly reduces the potential for errors that occur when distress surveyors process and relay information from one set of forms to another. The system has been developed so that a surveyor can conduct a distress survey on a computer without the need for a keyboard. The pen computer technology takes the concept of "user-friendly" technology to another level. Not only can this system be adapted to any distress survey procedure, but this technology appears to have significant potential for an almost unlimited array of comparable applications.
