he research includes the performance of short term and long term analysis in the field and laboratory.
On the one hand analysis criteria for an application of test methods of new products should be developed an on the other hand the effectiveness and life span of asphalt interlayers of the whole road body should be analysed and evaluated.
The result obtained by object related research should provide significant information about the improvement of crack penetration and reduction of thickness of the layers an cost saving. Furthermore the questions of the suitable application axtent (locally, plane) should be shown.
Research results of field analysis, supported by laboratory analysis, should give scientifically substantiated knowledges about the effectiveness of different materials in concrete area of application plane applications and their durability.
here conclusive results regarding the installations of asphalt interlayers in different position, in particular regarding the usage of asphalt interlayers between wearing course and binder course and the binder course and bearing course, should be worked out. The investigatins provide information, if an increase of the bearing capacity can be reched.
With the newly-developed systematic test methods, new products may be validated directly by themselves, so that uncertainties concerning the base suitability in introduction of new and innovative systems are lifted. Furthermore, mistakes in the installation of the asphalt interlayers may be avoided through decision support.
