Using Rubber Powder to Improve Freeze/Thaw Resistance of Concrete

Traditional concrete mixes used in highway construction projects are required to have an air void structure to aide with the continuous freeze/thaw cycles during winter seasons. Current practice is to use an Air Entrained Admixture (AEA) which at times has its difficulties when it is used in conjunction with some Supplementary Cementitious Materials (SCMs). The use of rubber powder in concrete is not a new idea but has not been greatly researched. The objective of this project would be to determine the rubber powder particle sizes and percentages for concrete mixes that could replace using an AEA while not jeopardizing the integrity of the final product.
