  3. 2. Evaluation of Asphalt Field Cores with Simple Performance Tester and X-ray Computed Tomography

    Författare :Florentina Angela Farcas; Björn Birgisson; Xiaohu Lu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; dynamic modulus; flow number; simple performance tester; X-ray computed tomography; air voids distribution;

    Sammanfattning : The importance of aggregate structure and air voids distribution for asphalt mixture rutting and cracking performance has been well established on the basis of experience and is well documented in the literature. Past and current investigations are limited to assessment of performance based on macroscopic behavior due to the difficulty associated with the quantitative measurement and analysis of the internal structure of asphalt mixtures.
