Specications
Cutback Asphalt:
• An asphalt cement which has been liqueed by
blending with petroleum solvents. Upon exposure to
the air, the solvents evaporate, leaving the asphalt
cement to perform its function of cementing and
waterproong.
When using cutback asphalts, extreme
caution must be used to prevent re or explosion. Do
not use open ames or sparks near these materials.
Use controlled heat only. Never use open ames to
examine tanks in which these materials have been
used or stored. Be sure all vehicles transporting
these materials are properly vented. Allow only
experienced personnel to handle these materials.
Be sure all applicable interstate and intrastate
commerce requirements are met.
Cutback asphalts are divided into three main grades.
1. Rapid Curing (RC) Asphalt: A cutback asphalt of
high volatility composed of asphalt cement using
naphtha or gasoline-type diluent.
2. Medium Curing (MC) Asphalt: Cutback asphalt of
medium volatility composed of asphalt cement and
kerosene-type diluent.
3. Slow Curing (SC) Asphalt: A cutback asphalt of low
volatility composed of asphalt cement and oils.
It is important to remember that
cutback asphalts are often used at temperatures
above their ash points. Serious injury can occur
from burns.
Material Considerations
NOTE: All information in the Material Considerations
section was obtained from publications of the
Asphalt Institute.
This section will help the operator better understand the
properties of the asphalt product being used (see Table
4-4. Guideline Temperatures For Liquid Asphalts).
The selection of the right product is generally
dependent on the following considerations:
1. Availability of various types of aggregate.
2. Availability of various liquid asphalt grades.
3. Climate conditions during applications.
4. Trafc conditions during application.
5. Contract specications.
NOTE: The information given in the charts in this section
is based on industry standards. It is important to
note that some asphalt product manufacturers
have grades or mixtures which do not conform
to industry standards. These materials are often
tailored to local conditions and may provide
superior performance to standard grades.
There are many types and grades of asphalt products.
The best results can be obtained through the trial of
several different types of asphalt and aggregates. The
following classications and grades of asphalts are
provided to help in the selection.
Asphalt Cement (AC):
• Asphalt that is rened to meet specications for
paving, industrial, and special purposes.
