\u00a0<\/a>
\nThe rapid increase in volume caused by the presence of water in hot bitumen and the subsequent overflow from a tank.<\/p>\nCutback bitumen:<\/b>
\nBitumen 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.<\/p>\n
Emulsifier:<\/b>
\nA chemical additive that is used to stabilize a suspension of bitumen in water in emulsion manufacture. The emulsifier determines the charge of the emulsion and controls the stability.<\/p>\n
Flash point:<\/b>
\nThe 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 34\/88 or equivalent in a Closed Cup or by IP 36\/84 in an Open Cup.<\/p>\n
Pyrophoric<\/b> deposit:<\/b>
\nA deposit, normally formed in an oxygen depleted environment, which can produce self-heating when its temperature or the surrounding oxygen concentration is increased.<\/p>\n
Archeology:<\/b>
\nPhysical study of the deformation of materials linked to viscosity, elasticity, plasticity and flow.<\/p>\n
Slurry Seal:<\/b>
\nA 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.<\/p>\n
Softening point:<\/b>
\nThe temperature in degrees C at which a bitumen attains a particular degree of softness with reference to test conditions prescribed by BS EN 1427 or equivalent.<\/p>\n
Soft Paving grade bitumen:<\/b>
\nPaving bitumen used in the manufacture of soft asphalt.<\/p>\n
Viscosity:<\/b>
\nA 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 72\/86 to characterise cutback bitumen in ‘seconds’. Kinematic viscosity is a derived characteristic that can be used to represent the fluid in technical calculations.<\/p>\n
