Stabilized Pavements for ALRS (Alternate Launch and Recovery Surfaces)
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).
