DURABILITY, AND STRENGTH REQUIREMENTS FOR LIME-STABILIZED LAYERS IN AIRFIELD PAVEMENTS. MIX DESIGN

Laboratory and field evaluation programs leading to the development of a design process for lime-stabilized airfield pavement layers are described. The entire process can be completed in 3 to 7 d. The design procedure, which includes selection of the optimum percentage of lime, rapid cure, durability testing, and residual strength requirements, uses common laboratory tests and requires no sophisticated equipment. It is reported to be appropriate for expedient and nonexpedient construction situations. Residual-strength curves were constructed from the results of a computer study that used a nonlinear finite-element code capable of simulating multiple wheel-gear loadings.
