Analysis of the sensitivity of the impact resonance frequency test as a tool to determine the elastic properties of bituminous materials

摘要: The modulus value of bituminous materials is a key factor in the design road pavements and estimation their life service. This parameter can be measured laboratory but, unfortunately, this requires deterioration pavement so as consumption time resources. Therefore, study analyses feasibility using impact resonance frequency tests an alternative to traditional methods for determining dynamic mixtures. sensitivity technique has been studied by analyzing its repeatability reproducibility, studying variations values modifying dimensions specimens, test temperatures types mixture tested. In addition, non-destructive compared with other used determine elastic properties materials. results show that could interesting tool characterize damage state asphalt layers.
