【 摘 要 】

The properties of asphalt concrete depend strongly on the interaction between binder and fillers/aggregates. Especially the development of microstructures of the bituminous binders employed and the interaction of the different parts of the microstructure with the solid surface of the filler particles are important parameters in determining the long-term performance of these materials. This paper describes a procedure for the preparation of an extracted field sample to be accessible for micro-structural investigations by atomic force microscopy and the results of such experiments.
