Asphalt Exam UPDATED ACTUAL Exam
Questions and CORRECT Answers
Difference between Asphalt and Tar - CORRECT ANSWER - Asphalt is soluble in
petroleum, tar is not.
Asphalt has bitumens, tar has low bitumens
Two Different Distillation Process to Produce Asphalt - CORRECT ANSWER - 1.
Fractional Distillation: Crude oil is heated, lighter oils vaporize and are drawn off, leaving
behind asphalt cement
2. Destructive Distillation: crude oil heated under pressure to higher temperatures than fractional
distillation
Penetration test - CORRECT ANSWER - -Test hardness and consistency
Viscosity test - CORRECT ANSWER - Tests resistance to flow
Superpave binder - CORRECT ANSWER - Another name for asphalt
Asphalt is selected based on... - CORRECT ANSWER - 1. Climate
2. Traffic
3. Location
Flash Point Test - CORRECT ANSWER - -Asphalt cements are heated before use in
construction
-Must understand what the max temp the material can be heated to safely
-Flash point = temp at which an instantaneous flash occurs
, Thin-film oven test - CORRECT ANSWER - -Used to simulate the aging that takes place
during the production of hot mix and during 1st year of pavement's life
Ductility test - CORRECT ANSWER - Workability
Solubility - CORRECT ANSWER - -Determines the purity of the asphalt cement
-The Asphalt cement will soluble in a particular solvent
RAP - CORRECT ANSWER - Recycled Asphalt Pavement
-Milling (grinding) removal of old asphalt pavements and reused in new hot mic asphalt
pavements
Asphalt can be modified into liquid form known as ___ or ____ - CORRECT ANSWER -
Cutback Asphalt or an Emulsion
Saybolt Furol Viscosity Test - CORRECT ANSWER - Measures anionic and cationic
emulsions
Distillation test - CORRECT ANSWER - Used to determine the relative proportions of
asphalt cement and water in the asphalt emulsion
Settlement test - CORRECT ANSWER - Detects the tendency of asphalt globules to
"settle out" during storage of emulsified asphalt
Sieve test - CORRECT ANSWER - Determine quantitatively the percentage of asphalt
cement present in the form of pieces, strings, or relatively large globules
Cationic - CORRECT ANSWER - Positively charged Emulsion
Anionic - CORRECT ANSWER - Negatively charged Emulsion
