The evaluation included tests on index properties, strength, chemical, petrographic and resistance-to-abrasion. The suitability or adverse features of the eight limestone deposits have been evaluated and the various engineering characteristics are discussed, based on a rating scheme, recommendations are made for the use of selected limestones as pavement materials in Egypt.
