✦ Synopsis

Transverse distribution of wheel paths (TDWP) model has been the basis for calculating load repetitions for many years. In fact, there is also longitudinal distribution of wheel paths (LDWP) along runway. Problems of present distribution model of wheel paths on airport was analyzed by contrasting the highway's model, and a curved surface distribution of wheel paths(SDWP) model for airport was put forward. In this paper, the DWP model has been developed from a curve to the curved surface. A Visual Basic program was written for calculating load repetitions. LDWP of the some aircraft was analyzed; a SDWP model of it was established and discussed. Based on the SDWP model, load repetitions of each point on runway can be calculated exactly. The SDWP model will power the pavements design theory towards different thickness design at each point in three-dimensional space.
