Grey Theory Application In Reforming In Old Cement Concrete Road Surface

Change secret one of the important method being cement concrete now road surface make over vainly,since all the time be doubly people paid close attention to ,changed black design vainly ,been under construction also in being perfected. Our country cement concrete road surface reforms and the project increasing by,people has a dialogue changing the black design plan's choosing the higher call for having applied put forward but,with changing various black scheme extensive use in reforming in old cement concrete road surface vainly. That the tradition white changes the black design plan sometimes is to make use of experience to design white according to old cement concrete road surface current situation changing the black design plan but,unable accurate reporting owes a design plan concrete advantage in changing the black project in white. At the same time, the choice in the scheme is hit by the various index very difficult to consider a design plan all round.the main Index body of a book is appraised synthetically by leading into the old cement concrete road surface,appraise a model estimating that the index has built white changing the black design plan,make use of a grey to be connected analysing the correlation degree following each indices of calculation scheme and be giving preferential treatment designing a scheme's turn ultimately for sure combining with changing the black design plan's one by one vainly degree value. The design plan go along to changes combining with the project example. adopt white finally is chosen through public appraisal,having testified that model applying has been feasible,at the same time has demonstrated the superiority should model and reckoning in the field of flexibility and the applicability.
