Artificial intelligence-based decision support technologies in pavement management

The field of road pavement engineering has seen an explosion of artificial intelligence-based applications since the late 1980s. Such applications are found at key stages of the decision process involved in pavement managemen t. In the analysis phase, they perform pavement diagnosis and deterioration modeling tasks. In the design phase, they enable rehabilitation needs to b e assessed and contribute to the identification and selection of maintenanc e actions. Finally, in the choice phase, they are applied for priority prog ramming of rehabilitation and maintenance. They either represent alternativ e approaches to existing systems or collaborate to make the overall system more efficient. The purpose of this article is to summarize the findings of up-to-dare research articles concerning the application of artificial inte lligence to pavement management and to illustrate the potential such tools can offer to pavement engineers. Artificial intelligence techniques include expert systems, artificial neural networks, fuzzy logic genetic algorithms , and hybrid systems.
