Abstract
This research studied the rate of residue formation of emulsified asphalts over time with respect to different aggregate substrates and curing conditions. Samples were prepared for testing by pouring an asphalt emulsion directly on an aggregate substrate and then cured within an environmental chamber which simulated field conditions. After the given curing times, the asphalt specimens were removed and tested in a dynamic shear rheometer using a strain-sweep test. Data obtained from different curing conditions and aggregate substrates were compared to make conclusions about the rate of stiffness gains in an emulsified asphalt material in relation to the binder/aggregate combination. Environmental factors such as temperature and humidity were also examined. The data was then utilized to optimize the construction process in terms of time between different construction steps.
