dc.description.abstract Emulsified asphalt is widely used in many highway maintenance and construction applications , and their effectiveness is greatly influenced by the construction process and climatic conditions at the time of application and soon thereafter . This research studied the rate of residue formation of emulsified asphalts over time , with particular emphasis on two key construction -related factors ; the aggregate it is in contact with , and the climatic conditions . Emulsified asphalts were sampled both from a plant location as well as three construction sites . Test specimens were prepared by pouring asphalt emulsion directly on aggregate substrates and then cured under different climate regimes in an environmental chamber . These climate regimes were selected to simulate field conditions and anticipated laboratory test environments . The stiffness of the asphalt was measured at specified time intervals by a Dynamic Shear Rheometer (DSR ) using a strain -sweep test protocol .
