TOMOGRAPHY
Tomography for asphalt refers to using tomographic imaging techniques (like X-ray CT, micro-CT, or industrial tomography) to study the internal structure of asphalt mixtures and binders. It allows researchers and engineers to visualize, in 2D or 3D, how aggregates, voids, and modifiers are distributed within the asphalt without damaging the full composition of product.
• Air void distribution – measure porosity, connected vs. isolated voids.
• Aggregate orientation and gradation – check whether large stones are aligned or segregated.
• Binder distribution – verify how bitumen coats aggregates and whether modifiers (e.g., rubber, SBS, microspheres) are evenly dispersed.
• Crack propagation – follow micro-cracks during mechanical testing.
• Moisture damage studies – observe how water infiltrates and weakens the structure.

RING AND BALL
(Softening Point test) is a standard method used in asphalt and bitumen testing. It determines the temperature at which a bitumen or asphalt binder softens enough to allow a steel ball to pass through it under controlled heating.
• Measures softening point of asphalt/bitumen.
• Indicates how the material will behave at high service temperatures.
• Helps compare binders (pure bitumen, modified binders like SBS, rubber-modified, etc.).
• Useful for quality control, performance grading, and binder specification compliance.

IR Spectrum
An IR spectrometer (infrared spectrometer) is an analytical instrument that measures how a material absorbs infrared light across a range of wavelengths.
• Identify chemical composition of bitumen and asphalt binders.
• Detect modifiers (e.g., SBS, crumb rubber, waxes, polymers).
• Monitor aging by analyzing oxidation products (carbonyl and sulfoxide functional groups).
• Compare reclaimed asphalt pavement (RAP) to fresh materials.
• Quality control in production and performance evaluation.
