A large number of laboratory tests were carried out, which took high temperature, fatigue and moisture resistance as main test items. The research not only evaluated the impact of waiting time for paving on the performance of epoxy asphalt from three aspects, but also integrated these items and put forward suggestions on the value of waiting time for paving by the grey relationship analysis methods. The results indicate that if the waiting time for paving is less than 30 min, the performance of epoxy asphalt will remain unchanged; however, when the grey connection performance declines to 80%, it will take the longest waiting time for paving, which can be as long as 80 min. This method can be applied to the researches and developments of epoxy asphalt as well as the evaluation of engineering practice.
