Treatment of cracking in rigid highway pavements using knowledge-based System

Highway engineers encounter numerous problems in the quality of rigid pavements; cracking types are most critical ones. Thus, deciding on appropriate controlling measures represents an essential mission. Normally, affect pavements as well increase initial cost. Although experts can control and solve these by using their tacit knowledge, novice cannot. Transfer expertise from to novices is difficult domain. Therefore, a system which could use share experience with other both during after project necessary. Without such transfer may repeat mistakes that have already learned avoid. Documentation, classification, computerization problems, causes, treatments, preventive actions be very helpful preventing them. This study aims describe development knowledge-based used overcome pavements. The also instructional tool for prospective highway engineers. In addition, archive organize raw knowledge utilized who work this field.
