Q.1) Based on your understanding of Aggregate tests answer the
following:
a. Show the differences between apparent specific gravity and
effective specific gravity by drawing sketches for their aggregate
particles.
b. Absorption and specific gravity are critical information for the
Hot Mix Asphalt design engineer, Why?
c. How you can make check that the fine aggregate sample reaches
the SSD case?
Q.2) Based on your understanding of Asphalt cement tests answer the
following:
a. Asphalt binder at room temperature is solid. To be able to mix
it with aggregate it must become liquid. How you can convert it to
a liquid material (show all methods)?
b. Is there a direct measure for asphalt binder aging? Mention it
or them and Explain your answer.
c. In solubility test AC should be moisture free, why?
P.S : Please do give a thumbs up since we as an expert
