Profile bitumen

Penetration testing : penetration grade bitumen is used for determination. In this test a standard needle under 100 grams in 5 seconds to pitch inside temperature is 25 degrees influence. The amount of influence in terms of tenths of a millimeter penetration is called. The degree of influence is less difficult pitch.

Viscosity: what is mental is more bitumen properties more solid than their shows. It is clear that mental health is lower at higher temperatures. This characteristic pitch with thirty Bolt Fyvrl or kinematic method measured.

Ignition temperature: The temperature thermal ignition if the temperature reached tar, gases rising from the flames approached, and at the level of the flame is ignited. The maximum temperature that can be bitumen in hot workshop is limited to the degree of combustion.

Weight loss: weight loss bitumen at high temperatures, evaporation of part of its oil and petroleum compounds. The characteristic properties of the pitch is important. Pitch in the oven at 163 ° C, weight loss and 5 hours (the baking asphalt Tghryby conditions) is measured.

Ductility or gum: if an example of pitch level 1 cm square at a rate of 5 cm / min draw, increasing the amount of property before tearing say Ankmy pitch.

Purity: Tetra know bitumen solvent and sulfur chloride, carbon is carbon. So if an example of pitch in each of these materials to solve, remains impurities and from there we can determine the purity of the pitch. Purity are: (bitumen sample weight) ÷ [(gross weight) - (weight bitumen)

Degree of softness: softness degree temperature with the temperature reaching the pitch, the pitch of the solid state mental comes. Any degree of softness More bitumen, less sensitive to changes in temperature. The soft bitumen is typically around 60 to 70.
