ABSTRACT
ABSTRACT: In the scope of the Private Public Partnership projects or build and maintenance project, the construction company can apply their knowledge, experience and competence in the form of the technical innovation to reduce the construction and maintenance costs. Hence, in this study asphalt material with long lifetime and low maintenance cost shall be developed. Therefore, several asphalt materials for base course, binder course and wearing course with different grading and binder types have been produced and tested in the laboratory of TPA, Cologne, Germany. The gained test results show, that the mechanical property and performance behaviour of asphalt mix can be improved significantly through optimization of mix composition. Hence, in this study the newly developed asphalt material DAsphalt (Deutsche Asphalt) has been selected for a highway construction with a contract: build and maintenance for a concession period of 23 years or design load of 50 Mio. 10-t ESAL by the international construction company STRABAG. The test result of analytical pavement design method show that the layer thickness of asphalt pavement with newly developed innovative asphalt DAsphalt can be reduced up to 10 cm compared to the conventional asphalt construction (thickness of 28 cm) according to German empirical design guide.
