ASPHALT COMPREHENSIVE EXAM
QUESTIONS AND SOLUTIONS STUDY GUIDE
●● Two Different Distillation Process to Produce Asphalt
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
Answer: -Test hardness and consistency
●● Viscosity test
Answer: Tests resistance to flow
●● Superpave binder
Answer: Another name for asphalt
●● Asphalt is selected based on...
Answer: 1. Climate
2. Traffic
, 3. Location
●● Flash Point Test
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
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
Answer: Workability
●● Solubility
Answer: -Determines the purity of the asphalt cement
-The Asphalt cement will soluble in a particular solvent
●● RAP
Answer: Recycled Asphalt Pavement
-Milling (grinding) removal of old asphalt pavements and reused in new
hot mic asphalt pavements
