Requirements for bituminous binders resulting from climatic conditions in Slovakia

Air temperature represents one of the most important climatic factors influencing the service efficiency and serviceability of asphalt pavements. The effect of climatic factors in the regions of Slovakia has not been taken into account in the stage of selection of binder into asphalts. The research in this field was conducted and representative air temperatures were determined for the summer and winter seasons. Results have shown that there are differences in air temperatures among regions of Slovakia. Differences are higher during the winter season than in the summer. The representative values of air temperatures for the summer and winter seasons were used to calculate temperatures of wearing, binder and upper base course during summer days. Physical principles of solar radiation and thermal propagation through the pavement were used for this aim. These values were then used for the determination of the requirements on bitumen properties to minimize rutting and cracking of asphalt pavements. Finally, requirements for softening point, breaking point, and range of penetration were determined for each of the asphalt layers of pavement taking into account maximum temperature for the summer season and minimum temperature for the winter season in these layers. Various combinations of softening point, breaking point and penetration are necessary to cover the variability of climatic conditions in Slovakia and thermal regime of asphalt layers.
