Hypertext databases are systems of text and graphics that allow a reader to "jump" from document to document depending on one's interests. A hypertext database has been developed for the construction inspection of asphalt paving. The purpose of the hypertext system is to provide an interactive reference manual for inexperienced paving inspectors. The database, developed with the cooperation of the New York State Department of Transportation, contains standard paving specifications, reference documents, articles of expert advice, and pictures illustrating paving techniques. Links are provided between documents, where appropriate, to allow the paving inspector to rapidly access information. The prototype system was developed using the Hyperties hypertext development software. The system is implemented on an IBM AT compatible computer. Links are provided from the hypertext database to a back propagation neural network that diagnoses pavement spreading problems. The capability to provide links to external programs allows artificial intelligence programs to be integrated with the database. Development of the asphalt paving system indicates the potential of using hypertext databases to provide information to inexperienced inspectors monitoring construction processes.
