Developing Expert System for Soil Stabilization under Flexible Pavement

Experts are, generally, busy and few in number. Getting them to work any time and in several locations is difficult, if not impossible, and requires time, cost and stress. Soil stabilization and modification represent an excellent domain for the development of an expert system, which contains a knowledge base of heuristic rules about types and remedies of stabilization. Thus, an Expert system program is a suitable solution together with the all the unpublished knowledge of the experts and combine it into a single accessible program, which could come in handy whenever a novice, student or practitioner engineer need it. The knowledge is extracted from literatures, questionnaire form and interviews with senior pavement engineers (expert), who have long expertise in flexible pavement engineering, especially in stabilization. The knowledge is then represented in knowledge base and encodes to be suitably entered in expert system builder shell (ES BUILDER). The system after being developed is have then to be evaluated by the experts and the users, to evaluate its efficiency and to recommend improvements and offer suggestions to improve the user interface. The overall commands after the evaluation stated that the software was very favorable. The users were very impressed by the system and it's efficient and solutions for the soil stabilization.
