Comparative consideration on the design relevant asphalt properties - test specimen production in the laboratory and paved asphalt layer
- Due to the publication of guidelines in Germany the possibility exists to offer analytical designed construction works within an alternative proposal. But the extent to which the test specimen production influences the design relevant properties (for the same asphalt mixture) is not sufficiently investigated at present. Objective of this research project was to determine the design relevant asphalt properties by tests and do comparative considerations on two selected locations within the renewal of a federal trunk road (Germany). For the comparative consideration of the design relevant asphalt properties mixture samples were taken during paving and afterwards drill cores were taken at the same locations. Fatigue tests and tests to determine the stiffness were conducted with the Indirect Tensile Test (ITT). Then design calculations having regard to the test results were performed. At this different bearing conditions of the asphalt package were considered. The calculated fatigue conditions were comparative evaluated and they are presented and discussed in this paper.
