QUALITY EVALUATION OF ASPHALT MIXES AND ASPHALT PAVEMENTS IN HUNGARY

During the last decade, since 1985, a complex asphalt mechanical test series has been developed in laboratories in Hungary. It has been extended to over one hundred asphalt mixes, mainly binder and wearing course materials, qualified from the aspects of expectable advantages and disadvantages. This method has also been applied to classify road building values, qualities of various normal and modified bitumen. Investigations are expected to evaluate asphalt materials -- in particular, bitumen -- under three main aspects. First, two mechanical tests are made concerning resistance to deformation, or proneness to rutting strength and coefficient of expansion of the given asphalt material are made for assessing winter cold behavior, data permitting to conclude on the temperaature of cracking rather instructive for winter cold behavior. Lastly, provided a stricter test is specified (e.g., for motorways), fatigue behavior of the given asphalt at a moderate mean temperature is investigated.
