Asphalt Pavement Construction Technology Expert System To Build Theories And Methods Of Research

Because the methods of constructing asphalt pavement are very complex and the difficulties are also very hard, furthermore, our country is short of experiences in this field, lots of technology problems appear on the spot, without rapid and effective solution. In order to solve these problems, this paper brings forward the method of intelligentizing constructing technology.This paper analyses the characteristics about technology problems in the asphalt pavement constructing and corresponding diagnostic tactic in detail, puts forward knowledge expressive means and knowledge storage mode, establishes knowledge base system (KBS) about asphalt pavement constructing. In order to enlarge knowledge source and improve KBS abilities to get knowledge, this paper also brings forward a new kind of knowledge acquirement model based on Rough theory. Considering the ways to solve technology problems about constructing asphalt pavement and the usual reasoning ways in expert system, this paper uses two kinds of reasoning mechanism: uncertain reasoning based on C-F model, fuzzy reasoning model based on fuzzy theory, and adopts mixed reasoning tactic that combined ordinal and converse reasoning method together.Based on the model which has built, this paper adopts Microsoft Access 2000 and Borland Delphi 5.0 to realize asphalt pavement construction expert system (APCES Vi .0) partly.
