  1. 1. Laboratory Seismic Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Hervé Di Bendetto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. LÄS MER

  3. 2. Resonance Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Mihai Marasteanu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance frequencies; Modal testing; Frequency response functions; Cyclic loading; Tension-compression tests; Complex modulus; Complex Poisson’s ratio;

    Sammanfattning : This thesis present novel non-destructive laboratory test methods to characterize asphalt concrete. The testing is based on frequency response measurements of specimens where resonance frequencies play a key role to derive material properties such as the complex modulus and complex Poisson’s ratio.
