Abstract:
Based on the characteristics and construction requirement of expedient airfield, the indoor tests of liquid limit, plastic limit, compaction, resilient modulus, CBR and unconfined compressive strength were designed for Jining soil. The outdoor test roads were constructed with con-aid soil stabilizer, cement, lime and cement-lime, the field tests of resilient modulus, CBR, deflection, soil pressure and rolling friction factor were done, the reinforcement effects of con-aid soil stabilizer and traditional inorganic binder were compared. Analysis result shows that the physical properties of water, resilient modulus and unconfined compressive strength greatly increase after adding con-aid soil stabilizer in Jining soil. After adding the AC101 stabilizer about 0.8%, plasticity index reduces by 21.9%, the optimum water content decreases by 3.1%, the maximum dry density and CBR value increase by 1.32%, 61.5% respectievly. After adding HOD1 stabilizer, CBR values increase by 212% with the flooding of test specimen and by 146% without the flooding of test specimen respectievly. In field tests, the bearing capacity of con-aid soil stabilizer reinforced soil is similar to cement reinforced soil and cement-lime reinforced soil, and is higher than lime reinforced soil during early period, but the growth rates of bearing capacities for cement reinforced soil and cement-lime reinforced soil are greater than con-aid soil stabilizer reinforced soil with the increase of age, the bearing capacity of con-aid soil stabilizer reinforced soil is similar to lime reinforced soil at 28 d. 14 tabs, 7 figs, 14 refs.
