Evaluation of the engineering properties of some Egyptian limestones as construction materials for highway pavements

Several hundred limestone samples representing eight different deposits within Egypt have been evaluated and results indicate that some of the deposits are adequate for use as highway pavement construction materials. 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.
