Strength Behaviour of Reinforced Soil-Aggregate Systems under Repeated and Cyclic Loading
Load-penetration response of reinforced and unreinforced soil-aggregate systems under repeated and cyclic loading is presented in this paper. Soil-aggregate systems are prepared by compacting soil in a mould and aggregates above the soil. For repeated load tests, the samples are prepared in a 150 mm diameter mould, whereas for the cyclic loading tests they are prepared in a 300 mm diameter mould. Geosynthetic reinforcement in the form of geotextile, biaxial geogrid and geonet is used at the interface of the soil-aggregate systems. Repeated load tests are carried out in a static load frame, whereas cyclic loading tests are carried out in a cyclic loading frame at a frequency of 1 Hz. The performance of reinforced soil-aggregate systems is compared with that of the unreinforced systems. The effect of type of reinforcement on the load-penetration response, secant modulus and resilient modulus is also studied. Results showed that geogrid is more effective in improving the load carrying capacity of the soil-aggregate systems compared to the other geosynthetics and the secant modulus and resilient modulus are not significantly altered by the inclusion of reinforcement.
