The object of the research were mastics containing limestone filler and mineral dust received from a dust collecting system. The main purpose of the analysis was the evaluation of the influence of ageing on the rheological properties of the mastics. The mastics were prepared with limestone filler and fillers received from the dust collecting system of an asphalt plant: basalt and melaphyre. Some samples were made by mixing fillers from the asphalt plant with the limestone filler. Special attention has been paid to the research into the influence of the filler type on the mastics rheological properties, before and after ageing, using the TFOT laboratory method. As the estimation measure of the change in the rheological properties caused by the ageing process, the change of the following values has been assumed: softening point, penetration at 5 and 25°C, ductility at 25°C and dynamic viscosity determined at 60. 90 and 135°C. All the tests were carried out before and after the ageing using the TFOT laboratory method.
