Abstract

Research on well-designed heavy-traffic flexible pavements in areas with elevated temperatures has shown that their service life is a function of the creep performance of their top asphalt layers. Ranking and predicting the creep performance of asphalt close to the field situation have always been a challenge for pavement designers in both the design and rehabilitation stages of flexible pavement in these critical situations.

To date, several laboratory test methodologies have been applied to model creep performance of asphalt, however, these methods have been unsuccessful compared with data from field assessments. The most important limitations, which make the modelling of the asphalt creep performance in the laboratory difficult, are outlined as: controlling the asphalt mix structure (i.e. air voids); providing in-situ asphalt confinement situations for laboratory samples.

It has been hypothesised that the Australian dynamic creep test can be redesigned to enable multistage evaluation of creep performance of asphalt mixtures to overcome the noted limitations. The research hypothesis is examined through a collaboration of development of two test methods. First, the Ultrasonic Wave Transmission technique (UWT) is used for non-destructive assessment of air voids distribution in the critical position in the centre of laboratory samples. Second, the Confined Dynamic Creep Test (CDCT) is developed to be able to perform multistage stress on the same asphalt sample. Finally, the combination of the two developed tests, MCDC+UWT is used with appropriate numerical and mathematical modelling to introduce a creep life prediction method.

The combination of MCDC+UWT tests together with numerical modelling greatly enhance the ability to rank and predict the creep performance of asphalt in varying operational conditions. This combination is also able to measure the compressive resilient modulus of asphalt at elevated temperatures and stresses.
