Asphalt Exam Questions With 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
