Abstract

There are two phases involved in any ROAD CONSTRUCTION project, namely design and construction operations. In the construction phase, type of materials and the respective strength play an important role in the construction cost as well as in FOREST ROAD longevity. Some soils, because of unsuitable technical characteristics, Create difficulties in the process of road building. In such cases, reclamation and stabilization of soil must initially be taken into consideration. In order to find out the pro procedure as well as kind and quantity of stabilizers it is needed to carry out studies and make comparisons among options. This is needed to make one able to choose the least cost method in attaining the objective. Soils of Namkhaneh district in KheiroodKenar forest were investigated in this study. A total of 61 samples were taken; soils with little susceptibility every 500 meters while soil with high susceptibility every 250 meters. In a geotechnical lab, the samples were studied and classified according to Granolometry Experiment, which consists of cieving (coarse materials) and hydrometry (fine materials). Through Ate berg limits experiments, liquid limits and plasticity limits were, determined. According to these experiments, soils were classified as SM.ML.CL.CH.In CH soil two subgroups of CHL and CHH (low and high liquid limit) were recognized After classification, density and optimal humidity in each class of soil was determined. The resistance in each soil class was obtained through CBR and plate bearing tests. Soils were mixed with 3,5,7 and 11 percent lime and then percent of optimal humidity was recalculated. This treatment was carried on for 48 hours under standard conditions (500°c). It was concluded that ML, CL, CH and CH soils reach their maximum resistance while mixed with 3, 5,7 and 10 percent lime 10 respectively. Because of their high Strength, MS soils were not tested in this study.
