Additive:
Any substance that is added in small proportions to bitumen to
impart some particular property e.g. improved adhesion,
emulsification etc.
Adhesion agent:bitumen
An additive that forms a water-resistant chemical bridge
between binder and aggregate surface, and hence improves
adhesion.
Anti-foam agent:
A substance, e.g. silicone oil, which when added to a bitumen
will reduce the surface tension and hence the frothing tendency
of hot bitumen in the presence of water.
Asphalt:
A mixture of mineral aggregate and a bituminous binder. A
natural mixture in which bitumen is associated with a
substantial proportion of inert mineral matter e.g. Trinidad
Lake Asphalt.
Note: In the US 'Asphalt' is used as the term for the bitumen
itself.
Asphaltenes:
The high molecular weight hydrocarbon fraction precipitated
from bitumen by a designated paraffinic solvent.
auto-ignition temperature:
The temperature above which a substance, when exposed to air,
might ignite in the absence of a source of ignition as a result
of contact with a hot surface or by self-heating
alone.
Auto-ignition temperature is not an intrinsic property of the
substance. It depends upon the surrounding physical
circumstances including the size and shape of the substance and
the degree of ventilation around it. Therefore, the
auto-ignition temperature for any substance can only be
indicated approximately.
Bituminous Binder:
A modified bitumen, or mixture of bitumen with fluxes, etc used
for road sealing or the manufacture of asphalt mixes.
Bitumen:
A virtually involatile, adhesive and waterproofing material
obtained by refinery processes from crude petroleum, or present
in natural asphalt deposits in some parts of the world. It is
black or brown in color and completely or nearly completely
soluble in toluene. It is very viscous or near solid at ambient
temperatures and softens gradually when heated.
Bitumen emulsion:
A dispersion of bitumen in water achieved by the use of
suitable chemical emulsifying agents. The emulsified bitumen
droplets may be anionic (negative charge), cationic (positive
charge) or non-ionic (neutral).
Blown bitumen (Oxidised bitumen):bitumen
Bitumen used in a wide variety of 'industrial' applications
including roofing, flooring, pipe-coating etc. They are
produced by passing air through soft bitumen/flux mixtures
under controlled temperature conditions. British Standard
grades (BS ***0) are normally designated by two numbers
representing the mid-points of their softening point and
penetration ranges.
Boil-over (Froth-over):
The rapid increase in volume caused by the presence of water in
hot bitumen and the subsequent overflow from a tank.
Cutback bitumen:
Bitumen whose viscosity has been reduced by the addition of a
relatively volatile flux such as kerosene, to render it more
fluid for ease of application.
Emulsifier:
A chemical additive that is used to stabilise a suspension of
bitumen in water in emulsion manufacture. The emulsifier
determines the charge of the emulsion and controls the
stability.
Flash point:
The lowest temperature at which the application of a small
flame in a prescribed manner causes the vapor above a flammable
product to ignite when the product is heated under prescribed
conditions. The flash point may be measured according to IP
Method *4/*8 or equivalent in a Closed Cup or by IP *6/*4 in an
Open Cup.

product to ignite when the product is heated under prescribed
conditions. The flash point may be measured according to IP
Method *4/*8 or equivalent in a Closed Cup or by IP *6/*4 in an
Open Cup.
Pyrophoric deposit:
A deposit, normally formed in an oxygen depleted environment,
which can produce self-heating when its temperature or the
surrounding oxygen concentration is increased.
Archeology:
Physical study of the deformation of materials linked to
viscosity, elasticity, plasticity and flow.
Slurry Seal:
A mixture of bitumen emulsion, well-graded fine aggregate,
mineral filler or other additives, and water. Slurry seals are
used as surface treatments in road maintenance.
Softening point:
The temperature in degrees C at which a bitumen attains a
particular degree of softness with reference to test conditions
prescribed by BS EN ***7 or equivalent.
Soft Paving grade bitumen:
Paving bitumen used in the manufacture of soft
asphalt.
Viscosity:
A measure of the resistance of a fluid to flow. Various scales
of measurement are used. The Standard Tar Viscometer (STV) is
used in the IP Method *2/*6 to characterise cutback bitumen in
'seconds'. Kinematic viscosity is a derived characteristic
that can be used to represent the fluid in technical
calculations.
