Silty or slimy sand stabilized with cement is used as a base or foundation layer when good quality natural materials are not available nearby. However, its mechanical characteristics are far from being mastered. In this paper, mechanical characteristics at different ages of silty sand stabilized with cement at different rates are studied. For this, specimen of silty sand stabilized with cement at rates of 2.5, 3.5 and 4.5% are subjected to the Modified Proctor test and to the compressive and tensile strength tests at 7, 28, 60, 90 and 360 days of age. The results show that compressive and tensile strengths increase with age and cement rate. The study of the different correlations between the resistances allowed the theoretical estimation of the parameters of roadway dimensioning in particular the fatigue resistance under a million loading cycles and the design fatigue resistance.
