Development and Application of Software Program for Pavements Design Methods

Abstract

AASHTO design procedures for pavements design (flexible, rigid and overlay) are reviewed, summarized and presented. Where necessary, tabulated data, charts and nomographs involved in the design are reproduced in equation form to suit Excel, the programming language employed in this study. Spread sheets are developed for the above categories of AASHTO pavement design. Results from the research approach adopted obtained by manual solutions deemed to be the same, except……. The developed spread sheets could not only be used in pavement design, but also can be used as a teaching tool for its simplicity, ease of use, and straightforwardness. These will avoid the use of tedious use of nomographs and trial and error techniques involved in the design procedures. These spread sheets can be developed further to include reminder types of pavements applying the AASHTO such as Low – volume gravel roads and other design methods e.g. Asphalt Institute.
