Abstract�� In order to make the future large transporter adapt to allowable load of present airport pavement-s requirement, after a great lot of investigations on pavement structure’s type, thickness, allowable load and maximal tire press accepted, advisory value of aircraft classification number(ACN)and tire press of future large aircraft was given. A 3-D finite element model which had nine slabs was established, the mechanical responses of cement concrete pavement was analyzed with advisory ACN and tire press under single wheel and main landing gear of IL-76, C-5. With the aim to reconstruct present airports as little as possible, the ACN between 16.1 and 24.2 and tire press under 0.80 MPa is reasonable for future large transporter. Allowable load of present airport pavement can ensure the future large transporter operate normally on 50 percent of present airports without reconstructing.
