Abstract :The current study comprises of different tests conducted for soil and aggregates used in the construction of dams and roads. Among these tests gradation insert ignore into journalissuearticles values(sieve analysis);, liquid limit, plastic limit, modified proctor, sand unit weight California bearing ratio insert ignore into journalissuearticles values(CBR); and hydrometer test were performed for soil mechanics. Gradation insert ignore into journalissuearticles values(sieve analysis); sand equivalent test, Loss Angles Abrasion insert ignore into journalissuearticles values(LA); test, soundness test, flakiness and elongation test, specific gravity and water absorption tests were performed for aggregate class. Based on observation regarding gradation test the collected sample is classified as A-6 type material. Data regarding plasticity index insert ignore into journalissuearticles values(PI); revealed that liquid limit is 38.1% while plastic limit is 24.7%. Proctor test exhibited that optimum moisture content insert ignore into journalissuearticles values(OMC); and maximum dry density insert ignore into journalissuearticles values(MDD); are 5.6 % and 2.293 g/cc respectively. Sand unit weight was noted as 1.547. The result for sand equivalent test is 83.3 %. LA and soundness test for coarse aggregate were analyzed as 24.0 % and 3.7% respectively. The result for flakiness and elongation test were 10% and 11% while the result for Specific Gravity and water Absorption test were analyzed as 2.647 and 1.6% respectively. The result obtained from all these tests are according to the American Association of state highways and transportation officials insert ignore into journalissuearticles values(AASHTO); standard. The materials with unsatisfactory result are strongly suggested to be avoided.
