Abstract:

The soil resilient modulus is an important parameter in the pavement structure design. It influences directly on safety and economy of the pavement structure. The indoor vibratory compaction is a new method of forming specimen, which can simulate the properties of vibratory compaction in the real road construction. The relationship between the resilient modulus of compacted loess and its physical indexes such as dry density, water content, consistency and compaction degree and age is analyzed.Therefore, the resilient modulus of vibratory compacted loess is compared with that of the heavy rammer loess. The results show that the correlative relations are presented between resilient modulus of compacted loess and those physical indexes mentioned above. The resilient modulus of indoor vibratory compacted loess is larger than that of indoor heavy rammer loess under the recommended parameters’ condition.

Key words: compacted loess, resilient modulus, vibratory compaction, heavy rammer
