Asphalt UPDATED ACTUAL Exam Questions and CORRECT
Answers
Ductility test - Workability
Solubility - -Determines the purity of the asphalt cement
-The Asphalt cement will soluble in a particular solvent
RAP - 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 ____ - Cutback Asphalt or an
Emulsion
Saybolt Furol Viscosity Test - Measures anionic and cationic emulsions
Distillation test - Used to determine the relative proportions of asphalt cement and water in the
asphalt emulsion
Settlement test - Detects the tendency of asphalt globules to "settle out" during storage of
emulsified asphalt
Sieve test - Determine quantitatively the percentage of asphalt cement present in the form of
pieces, strings, or relatively large globules
Cationic - Positively charged Emulsion
Anionic - Negatively charged Emulsion
, Basic requirements for an asphalt pavement - 1. Have sufficient total thickness and internal
strength to carry expected traffic loads
2. Prevent penetration or internal accumulation of moisture.
3. Have top surface that's smooth and resistant to wear, distortion, skidding, and deterioration by
weather and de-icing chemicals
Courses of Asphalt Pavement (Top to Bottom) - 1. Surface Course
2. Binder Course
3. Base Course
4. Sub-base course
5. Subgrade
Factors that determine asphalt pavement thickness - 1. Traffic
2. Subgrade strength
3. Strength and other influencing characteristics of the material available or chose for the layers
or courses in the total asphalt pavement structure
4. Any other special factors
The weight and volume of ____ that a road is expected to carry initially and throughout its
design life influence the required thickness of asphalt pavement structure, as well as mix
selection and mix design. - Traffic
HMA (hot mix asphalt) - Asphalt concrete paving mixtures prepared in a hot mix plant
-Considered highest quality type of asphalt mixture bc the plant removes all ambient moisture
from aggregates which ensures the best bond between aggregates and asphalt binder
