ASPHALT TEST QUESTIONS AND ANSWERS
The three types of asphalt are asphalt emulsion, asphalt cement, and asphalt
cutback.
ANSWER: Asphalt cement is a mixture of hydrocarbons with varying weights.
Asphalt gets harder and more viscous as it moves to larger weights. (The sticky
substance) Asphalt concrete is made up of asphalt cement and agg.
ANSWER: Describe asphalt cutback by dissolving asphalt cement with a
solvent. It evaporates when sprayed onto pavement or combined with agg,
leaving behind asphalt residue as a binder. (used for emulsion and maintenance)
However, cuts are costly and harmful.
Describe asphalt emulsion. ANSWER: Asphalt is dissolved in water as an
emulsion instead of in a solvent.
Name a few applications for asphalt: ANSWER: Asphalt is primarily utilised in
pavement construction and maintenance; it is also used to waterproof and seal
roofs and subterranean foundations; asphalt concrete is used to mend asphalt
and PCC pavements.
In pavement repair, liquid asphalts like emulsions and reductions are utilised.
What frequently influences asphalt's consistency? ANSWER Temperature: too
cold will cause the mixture to become too brittle and break. The mixture will
flow easily if it is overheated, causing permanent distortion (rutting).
The main hydrocarbons that comprise asphalt are carbon and hydrogen, with
trace amounts of sulphur, nitrogen, and oxygen.
The three configurations of asphalt are as follows: 1) aliphatic or paraffin
chains, either straight or branched
2) The highest hydrogen to carbon ratio is found in saturated rings.
3) aromatic or unsaturated rings.
