Brief description

In order to consider the design-relevant asphalt properties, it is necessary to determine these by means of tests that are as simple as possible to carry out. The present offer includes the execution and evaluation of fatigue tests on asphalts with different types of aggregates, binder provenances, bitumen hardnesses and binder modifications. In the evaluation of these tests, a possible modeling of the design-relevant asphalt properties on the basis of the mixture properties, a database with the test results with the possibility of updating these as well as a working instruction for the test procedure in the determination of the design-relevant asphalt properties are to be developed. Transfer parameters/functions from the test results for the design/forecast are also calculated.
