Abstract

A previous experimental study has suggested that asphalt concrete using hydrated lime
to partially replace the conventional limestone dust filler at 2.5% by the total weight of
all aggregates had an optimum improvement on the key mechanical properties, fatigue
life span and moisture susceptibility. To promote the real-world application, more
knowledge of the thermal response of the modified asphalt concrete is needed to
provide the required information for pavement design. For the purpose, an
experimental test, under three temperature conditions, has been conducted to study the
fatigue of an optimum mix for wearing surface. Based on the experimental data, a
thermal-fatigue characterization model has been derived for the asphalt mix. At the end
the model has been implemented on a case investigation to analyse the seasonal thermal
effect on the fatigue of pavement constructed using the optimum hydrated lime
modified asphalt concrete
