How the MFI value of Asphalt can improve Road Quality?

Asphalt, also known as bitumen is glutinous, black, and highly viscous liquid or semi-solid form of petroleum. It is majorly used in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main applications are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. For road construction, the asphalt material is used as binder substance, and its processing quality holds a lot of importance in road construction quality. In this blog section we will talk about asphalt and how testing its processing quality using plastic testing instruments such as mfi testing machine can help in building high quality road.

The majority of asphalt used commercially is obtained from petroleum. Nonetheless, large amounts of asphalt occur in concentrated form in nature. Naturally occurring deposits of bitumen are formed from the remains of ancient, microscopic algae (diatoms) and other once-living things. These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 °C) and pressure of burial deep in the earth, the remains were transformed into materials such as bitumen, kerogen, or petroleum.

Testing Asphalt’s MFI value

To evaluate the MFI value of asphalt an accurate testing instruments is requires such as The Presto Melt Flow Index Tester – NXG Model. It is a reliable instrument used for evaluating and analysing the flow properties of molten plastics or resins. The determination of the melt flow index of plastic materials is an important parameter in the evaluation of its quality. Thus, the model is a must-have for all manufacturing units dealing in plastic products. The instrument is introduced with Human Machine Interface Multicolour touch screen display to offer user-friendly operations.

The latest Touch Screen Model is designed to automatically calculate the melt flow index of the test sample. The Temperature can be set anywhere between Ambient to 400°C. The equipment offers easy changeability of weights and auto cutting facility of sample. It has a digital PID temperature controller for accuracy and reproducibility. The equipment is built on a rigid metallic base plate and finished in autumn grey & blue combination paint and bright chrome/zinc plating to give it a corrosion resistant finish.

The instrument comes complete with Instruction Manual, Electrical Wiring Diagram and Calibration Certificate traceable to NABL approved labs.
