Explain following objectives of hot mix asphalt (HMA).i) Deformation resistance ii) Moisture damage resistance
Several types of fillers, such as crushed fines, portland cement, lime, fly ash, and carbon black, can be added to asphalt concrete. Fillers are used to satisfy gradation requirements of materials passing the 0.075 mm sieve, increase stability, improve bond between aggregates and asphalt, or fill the voids and thus reduce the asphalt required.
Question 8
Asphalt binders and mixtures are complex materials because they:
are rheological and thermoplastic and age
O are homogeneous within the same grade
are not sensitive to time of loading or temperature
are manufactured to exact chemical compositions

- Make a comparison between Cutback ?Asphalt and Asphalt emulsionarrow_forwardWhat 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.
