Asphalt and bitumen mixture testing equipment manufacturers in India must deliver tight temperature control, because binder results shift with a degree or two. Civil Mechanical India is among the suppliers in India offering thermostatic baths, ovens and compactors for hot-mix plant labs and road agencies.
Binder tests and mix tests are kept distinct in this group. Binder instruments cover softening point, ductility, flash and fire point, loss on heating, viscosity and the rolling thin film oven for short-term ageing. Mix instruments cover the gyratory compactor, the indirect tensile frame, the wheel tracker for rutting and the centrifuge extractor that reports bitumen content and allows gradation of the recovered aggregate.
Plant labs run binder tests on each delivery and mix tests on every production lot, so the mix side tends to be larger and more automated.

Bitumen and asphalt are thermoplastic materials, so their instruments revolve around controlled heating, cooling baths, viscosity and repeated loading. Cement-mortar equipment instead handles hydraulic binders that set and gain strength with water, so it uses moulds, flow tables and crushing frames. Road projects usually need both: cement testers for concrete structures and asphalt testers for the wearing and base courses.

The complete Asphalt and Bitumen Mixture Testing Equipment range (10 products), in alphabetical order:
Confirm the method, for example IS 1203, IS 1208, IS 1209, ASTM D36 or D113, since baths, thermometers and moulds differ. Check temperature range and stability, number of stations, heater safety cut-outs and fume extraction for flash point tests. Ask for spare moulds, rings, balls and calibrated thermometers in the same quotation.
Most plant labs start with bitumen content extraction, gradation by sieves, Marshall or gyratory compaction and a density determination. Rutting and indirect tensile tests are added when the specification covers modified binders or heavy traffic roads. Review the contract requirements before choosing, since the compactor type alone changes the order value considerably.
It simulates hardening of bitumen during mixing and laying, so the aged residue can be retested for penetration or viscosity. Check bottle capacity, rotation speed, air jet flow and temperature stability at 163 deg C, because small deviations change the mass loss and the ageing index.
Road contractors, hot-mix and emulsion plants, oil refineries and bitumen blenders, highway authority quality labs, and independent testing houses are the main buyers. A usual lab setup pairs binder instruments with sieves, ovens and balances, then adds a compactor and extractor to manage mix design and production control. Research institutes also buy the viscometer and wheel tracker for modified binder studies.
Yes, provided the viscometer, ductility bath and softening point tester cover the temperatures used for modified grades. State the grades, such as PMB or CRMB, so spindles, heating range and stirring arrangements are selected correctly.
It compacts asphalt specimens by combined pressure and gyration to reproduce field density, and records height change to indicate compactability. Mix designers use it to select binder content and aggregate blends under Superpave or equivalent methods.
Yes. Civil Mechanical India supplies against road and highway department tenders in India. Send the schedule of instruments, the standard and the quantity, and a clause-wise response can be prepared.
Centrifuge extraction uses solvents that need a ventilated enclosure, spark-free motors and correct disposal. Confirm your lab has an extraction hood and solvent storage before ordering, or ask about alternative ignition-method equipment.
Export supply is available. Please state the destination, supply voltage and applicable standard, such as ASTM or EN, so that the baths, scales and thermometers are configured for that method.
