Name three uses of asphalt emulsion. - CORRECT ANSWERS 1. Chip Seal - produced by
spraying the road surface with asphalt emulsion followed by a layer of gravel.
2. Slurry Seal - produced by the creation of a mixture of asphalt emulsion and fine aggregate,
then spread on the surface of a road.
3. Cold mixed asphalt - produced from asphalt emulsion. Used to create pavements similar to
hot-mixed asphalt.
Why is asphalt
emulsion preferred over asphalt cutback? - CORRECT ANSWERS Asphalt emulsion is
preferred over asphalt cutback because of the
1. Higher penetration quality of the emulsions.
2. Capable of binding the aggregates more effectively.
Define what is meant by temperature susceptibility of asphalt. - CORRECT ANSWERS
The viscosity of the asphalt decreases and the asphalt softens as the temperature increases.
The asphalt hardens and becomes brittle when the temperature goes down.
Are soft asphalts used in hot or cold
climates? - CORRECT ANSWERS Soft asphalt pavements should be used in COLD
climates.
Hard asphalt pavements should be used in HOT climates.

Briefly discuss the chemical composition of asphalt. - CORRECT ANSWERS Asphalt is a
mixture of large variants of hydrocarbons. The hydrocarbons consist of hydrogen and carbon
atoms.
There are minor components of Sulfur, Nitrogen and oxygen in hydrocarbons.
The asphalt is made up of asphaltenes and maltenes. The maltenes are a mixture of resins and
oils. The high viscosity and adhesive property is imparted to the asphalt by the asphaltenes and
hence the name.
What is the engineering application of:
a. flash point test - CORRECT ANSWERS The flashpoint of asphalt is the temperature at
which the asphalt catches fire. The flash point is important to know in order to avoid any
hazards.
What is the engineering applications of:
b. RTFO procedure - CORRECT ANSWERS Rolling thin film oven (RTFO) is conducted in
the asphalt concrete to impart an artificial aging to the asphalt during the production of asphalt
concrete.
The asphalt is placed in glass bottles and rotated vertically in an oven.
The mass loss during the aging process is calculated using this test.
What is the engineering applications of:
c. rotational viscometer test - CORRECT ANSWERS Rotational Viscometer test:
