摘要
A method of selecting a crack resistant layer to be applied to an existing surface, the method comprising the steps of: selecting at least one emulsified bituminous binder to examine, where the emulsified bituminous binder comprises bitumen, one or more emulsifier, and one or more polymers, where the one or more polymers, the one or more emulsifier, or both include a sufficient amount of conjugated diene such that at least 2.5% of the weight of the emulsified bituminous binder residuum comprises conjugated diene, preferably at least 3.0%, more preferably at least 3.5%, and most preferably 4.0%; forming at least one bituminous mixture comprising the emulsified bituminous binder and an aggregate; testing each bituminous mixture for fatigue properties; and selecting a bituminous binder for use in the crack resistant layer. The method may further comprise the steps of testing the bituminous mixture for fracture energy and selecting the emulsified bituminous binder for use in the crack resistant layer based on fatigue properties and fracture energy properties, and/or testing the emulsified bituminous binder residuum for fracture energy and selecting the emulsified bituminous binder for use in the crack resistant layer based on fatigue properties and bituminous binder residuum fracture energy properties.
