Comparison of the resilience modulus at different moisture contents using the cyclic CBR test to promote nature tourism

Jon Ander Zabala, Lenka Sevelova


The detailed and sensitive determination of input characteristics for low volume road design is important especially for the natural environment in conjunction with recreation activities. Existing methodologies for the pavement structure design consider the Resilience Modulus to be the fundamental property to characterize the materials of low volume roads. In order to obtain this modulus the cyclic CBR test has been used. Two different test variants have been carried out, the first one applying a constant 2.5mm penetration repeatedly until the elastic deformation reaches a constant value, and the second one applying a constant stress of 210 kPa. The material examined has been tested at fifteen different moisture contents and for each moisture content two different material compaction levels have been considered. Thus it has been possible to analyze the difference between the Resilience Modulus values obtained from the two different variants of cyclic CBR tests, for different moisture contents as well as for different material compaction levels.
