Abstract:

An ALRS Stabilized Material Pavement Analysis System SPAS is proposed. An intact slab approach based on ILLI-PAVE analyses and Meyerhof ultimate concepts is recommended. The study of the WES Test Section data indicated the validity of SPAS and facilitated the development of transfer function concepts relating ALRS pavement response to performance. Inputs required to establish the stabilized base thickness for an ALRS pavement F-4 loading are the field strength of the stabilized material and the ERi measure of resilient modulus of the fine-grained subgrade. A properly designed ALRS pavement for F-4 loading can accommodate a reduced number of C-130 and F-15 load applications. The SPAS thickness design concepts based on an intact slab approach are applicable to a broad range of cementitious-stabilized materials soil-cement, lime-fly ash-aggregate, soil-lime mixtures, similar high-strength and modulus materials.
