1. What is the difference between tar and asphalt cement? List the main uses of asphalt cement. 2. How is asphalt used in "cold" applications? Comment on the differences between the methods used to make asphalt liquid at ambient temperatures. 3. Define what is meant by temperature susceptibility of asphalt. Discuss the effect on the performance of asphalt concrete pavement. For example, are soft binders used in hot or cold climate? 4. What is the significance of each one of the following tests? a. Flash point test b. Rotational Viscometer test c. Dynamic Shear Rheometer test d. Bending Beam Rheometer test e. Solubility test f. Penetration test g. Ductility test 5. What are the different methods used to grade asphalt binders? 6. Temperature has a large effect on the asphalt consistency. Plot a typical relationship between asphalt consistency (for example viscosity) and temperature. Identify on the plot, the temperatures at which main distresses occur
