Conclusion
Although some engineering properties tend to be better by the content of concentrated latex added, it needs to consider some difficulties in preparing mixtures, mixing temperature, mixtures homogeneity, the increased viscosity, and workability. By considering under the laboratory tests for engineering properties of both binders and asphalt concrete mixtures Concentrated latex was the suggested appropriate proportion in blending with asphalt cement. approximately three times better than AC 60/70. Moreover, it requires less optimum binder content than AC 60/70 which may helps in reducing construction capital and long-term maintenance cost for road pavement.
