Questions & Answers PDF
1. Describe the significance of maintaining the correct residual asphalt cement
content in tack coat applications.
Lower residual content reduces the cost of materials.
Higher residual content improves the color of the asphalt surface.
Maintaining the correct residual asphalt cement content ensures
proper bonding between layers and prevents delamination.
Residual content has no impact on the overall quality of the asphalt.
2. What is the proper range of tack coat application in gallons per square yard?
0.10 to 0.20 gallons per square yard
0.15 to 0.25 gallons per square yard
0.05 to 0.15 gallons per square yard
0.01 to 0.05 gallons per square yard
3. If a contractor is preparing for an asphalt overlay project, which construction
document should they consult first to understand the project requirements?
Change Orders
Contracts
Specifications
Drawings
4. Describe the significance of using the correct tack coat application rate in
asphalt construction.
, Tack coats are only necessary for the initial layer of asphalt.
Using the correct tack coat application rate ensures proper bonding
between layers, which enhances the durability and performance of
the asphalt.
The tack coat application rate is irrelevant to the overall quality of the
asphalt.
Higher tack coat application rates always lead to better results.
5. Approved additions and revisions to the standard specification are called:
Work Orders
Plans
Supplemental Specifications
Cheat Sheets
6. What is the typical residual asphalt cement content range from a properly
applied tack coat in gallons per square yard?
0.05 to 0.15 gallons per square yard
0.10 to 0.20 gallons per square yard
0.15 to 0.25 gallons per square yard
0.01 to 0.05 gallons per square yard
7. Describe the role of tack coats in preventing issues during asphalt overlay
projects.
Tack coats are applied to reduce the temperature of the asphalt
during paving.
Tack coats are primarily used for waterproofing the asphalt surface.
