Investigation on the Mixing Stability of Asphalt Emulsion

Mixing stability is dependent on mixing method, superplasticizer, and emulsion type. The premixing cement method, superplasticizer, and good asphalt emulsion can increase the critical particle volume fraction of CA paste, which is helpful in achieving a low water–to–cement mass ratio (W/C).

Mix temperature will be dependent on the grade of asphalt used in the mix. The less viscous the asphalt, the lower the temperatures should be. The more viscous the asphalt, the higher the temperature can be. During mix design temperatures are specified for proper mixing and for compaction. These are good targets with which to start a project.

classified as the dry method and the wet method (3). The wet method involves dispersing the CRM particles into the asphalt cement to produce what is called asphalt rubber (AR) which in turn is used to produce hot-mix asphalt concrete. The dry process involves mixing the CRM with the aggregate before introducing the asphalt cement to the mixture.
