What are three advantages of using asphalt emulsions versus using cutback asphalts? Solvents in cutbacks add to green-house gas emissions while emulsions do not. Water is currently more expensive than solvents used in cutbacks. Emulsions are liquid at room temperatures while cutbacks are solid and need heating to become liquid. Cutback asphalts only need to be heated to 600C while emulsions require high heat to become liquid. Asphalt emulsions only need to be heated to 600C while cutback asphlats require high heat to become liquid. Emulsions are liquid at room temperatures while cutbacks are solid and need heating to become liquid. Can only add a positive or negative charge to the cutback asphalt to help the binder adhere to the aggregate. Water in the emulsion allows for better bonding with the aggregate. Cutback asphalts only need to be heated to 600C while emulsions require high heat to become liquid. Solvents in cutbacks are more…
