Abstract
Soil stabilization may be defined”the process by i,hich the physical and chemical properties 0 , soil and soil-aggregat mixtures may be improved or altered bl, e*.ther mechanical trea¬tment or with the addition of chemicals. One of the primary purposes of stabilization is that ofusing ’ocally available material for sub-base and bases to effect an economical des¬ign of the subgrade-base-pavement combination. In Alexandria,
subgrade failures are frequent under styeU ment in the zone of Smouha and El-Seyouf. PLirthermo2e, ear In fainnroads, in the neighbourhood of Alexandria, fire muddy in iinte” and not suitable for any kind of transportation during lthe major art of the wet season. The subgrade soil conditions in the a&ricultu the neighbourhood of Alexandria at Smouha, and provinces are similar since both areas were developped by drying a great part of Maruit Lake.In spite of the frequent subgrade and pavement failure in these areas, no attempt has been made to make use of the well-known methods of Soil-Stabilization to develop reliable and economic methods of pavement design and construction. One successful method is the stabilization of such subgrade soils ~7,rith lime to produce a chemical change and a cementing action ’,.’-at will improve the poor properties of 7o
