The strength properties of a Peter miller-processed and -compacted snow runway test strip at McMurdo, Antarctica, and the snow pavement performance during simulated C-130 and C-121 aircraft wheel-load tests are discussed and evaluated. The correlation of shear strength with ram hardness and unconfined compressive strength of high-density snow is discussed and an approximate relationship is developed. Data from actual aircraft and simulated aircraft wheel-load tests on snow pavements are compared with previously developed criteria for snow pavement supporting capacity. (Author)
