I. Abstract:Permanent Deformation Coefficients, such as alpha () and mu () show
influence of mixtures properties on flexible pavement probable rut development.Assessment of these coefficients requires a data bank of mixture parameters
(aggregate type, gradation, binder type, contents and mixtures volumetric),
temperature and loading conditions. A comprehensive laboratory study was carried
out on 22 mixtures ranging from fine to coarse with two method of adding lime to
aggregate which are used in typical hot weather areas of Iraq. The specimens were
