Influence of Asphalt Mixture Ageing and Lowered Laboratory Compaction Rate on Stiffness and Cracking Behavior
Original language description
Ageing is one of the fundamental phenomena related to bitumen and asphalt mixtures. Traditional problem of asphalt testing is that most of the characterizations done presently reflect ageing only in limited manner. Nevertheless the behavior of a pavement structures is on the other hand dominated by natural effects like ageing. Similarly very important issue related to good job quality is in case of asphalt mixtures the compaction rate of asphalt layers. Compaction rate is often a factor which has very significant impact on the durability, but it is often neglected or the attention which is given to proper compaction is not sufficient enough. In this research the asphalt mixtures with different compaction rates were exposed to artificial laboratory ageing to evaluate the effect on selected asphalt properties of both impacts. The assessed properties were stiffness modulus at three testing temperatures (0 °C, 15 °C and 30 °C) and crack propagation test at 0 °C. The properties were always determined for virgin (unaged) as well as aged test specimens. The ageing indexes were calculated for both of the characteristics discussed in this paper.
