Civil Engineering Materials Exam #3 Questions with
Correct Answers
difference between concrete & bituminous materials Correct Answer-
water & cement provide bonding for concrete aggregate with the need
for water, while asphalt cement provides bonding for bituminous
materials without water
bitumen Correct Answer-viscous liquid or solid essentially hydrocarbons
and their derivatives. soluble in carbon di-sulphide. Non-volatile, softens
when heated. Black or brown coloring. Water-proofing and adhesive
properties. Natural deposit (petroleum). Use for roads as asphalt and tar
tar Correct Answer-viscous black liquid obtained by destructive
distillation of coal, wood, shale
distillation Correct Answer-subjected to heat and high pressure without
access to air
sources of natural asphalts Correct Answer-trinidad lake
trinidad lake Correct Answer-from the island of trinidad. approximately
40% asphalt + 30% water + 30% mineral matter (clay)
types of natural asphalts Correct Answer-gilsonite & petroleum asphalt
, gilsonite Correct Answer-practically pure asphalt. 90% soluble in CS2.
very hard. primary use in asphalt paints and asphalt floor tiles
petroleum asphalt Correct Answer-primary source from the refining of
petroleum. Higher grade crude oil --> 10% asphalts. Lower grade crude
oil --> 90% asphalts
uses of asphalt Correct Answer-paving (road construction), roofing,
protective coatings
classification: paving (road construction) Correct Answer-primarily
produced by the vacuum and steam refining and solvent deasphalting
process.
emulsified asphalts Correct Answer-the suspension of small globules of
one liquid into another without intermixing
roofing Correct Answer-semi-solid or solid. shingles and roll roofing
protective coatings Correct Answer-pipe coatings, reservoir and canal
linings. highly blown asphalts and finely divided mineral fillers.
