Students have asked these similar questions
C/ What are the sources of asphalt (in your wards)?"
Describe the two types of asphalt production plants. Compare and contrast.
Most large projects use HMA (hot mix asphalt) but sometimes we use cold mix asphalt made
from cutbacks. Describe how cold mix asphalt works and what type of projects it is typically
used.
. Describe the steps for ASTM D4402
3. Explain how asphalt mixes get placed in the field.
9. The NCDOT specified a PG64-28 binder for its new roadway project. You are working in a
you
material testing lab to provide Quality Assurance for this project. What temperature would
conduct
A bath plants mixes 6 tons of asphalt mix with an average mixing time of 1.5 minutes. Assuming plant efficiency of 75% what is the plants production in tons per hour?
