Flexible pavement design and management

An operational pavement systems model (SAMPS), that organizes the over-all influencing factors such as materials characteristics, construction techniques, maintenance requirements, and economics within a suitable framework for flexible pavement design and management has been formulated. A computer program has been prepared using 58 to 100 input variables, and the AASHO interim guides for design of flexible pavements as the structural subsystem. Detailed descriptions for user guides, input forms and data feedback, and storage systems are needed for more easy implementation. the procedures are being subjected to a sensitivity analysis and pilot testing. Project efforts were divided into two separate but coordinated activities, namely, systems formulation, and materials characterization.
