Hypertext is a data base system of text and graphics that allows a reader to jump from idea to idea depending on one's interest. Hypertext can be applied to construction to provide interactive reference manuals for controlling construction operations. Other potential applications for hypertext in construction include data bases of regulatory information and as advice programs for planning and estimating. An example hypertext data base that provides advice for the construction of asphalt pavements is described. The purpose of the asphalt hypertext system is to consolidate information on the construction inspection of asphalt paving in a single data base. The prototype system was developed using the Hyperties hypertext development program. The system is implemented on an IBM-AT compatible computer. Hyperties allows drawings to be incorporated in a data base. The asphalt paving system includes drawings of the major components of the asphalt paving machine. The data base has articles of expert advice, standard specifications, and reference documents. Potentially, hypertext data bases can provide construction engineers with improved access to information about construction.
