Used to perform reliable analysis on bituminous mixtures utilizing the perchloroethylene (PCE) or tetra-chloroethylene solvent which is classified: R40 not cancer producing (see note*), for quantitative determination of binder or bitumen contained in pavement samples and hot mixed mixtures.

Other Details:

  • The system performs in only one complete automatic cycle:
  • the washing, disaggregation and separation of the bitumi-nous mixture;
  • the separation of the filler from the solution formed by solvent, bitumen and filler;
  • the recovery and distillation of solvent material allow-ing a further utilization.
  • This unit, in a short time, performs out a serie of analysis that normally require a long time and labour, by reducing extraction costs.
  • The unit comprises:
  • An electromagnetic sieving unit, insuring high quality double vibrating action (vertical/rota-tional), with solvent spraying cover for washing and disaggregation of the sample.
  • A continuous flow filterless centrifuge having rotation speed of 11000 rpm equipped with a stainless steel beaker dia. 120 mm., filler capacity approx. 400 g.
  • A solvent recovery unit having reclaiming capacity of approx. 50 l/h, equipped with cooling system foreseen of devices switching ON and OFF the unit to fully automatically perform the test
  • A separate control panel allows to program all these func-tions in a fully automatic system. It is also possible to select the manual function allowing to activate each specific function previously analyzed.
  • This unit is supplied complete with:
  • Two stainless steel beakers dia. 120 mm
  • Four stainless steel sieves dia. 200 mm openings: 0,075 - 0,250 - 0,800 - 1,6 mm
  • One Sieve Frame only dia. 200 mm. to improve the capacity of the first sieve.
  • Set of O ring gaskets for sieves.
  • Sieves with different openings are available on request. A complete extraction cycle is performed ot in approx. 25 minutes and the max. quantity of mixture per extraction is 3500 g

This Gyratory Compactor, entirely developed and manufactured by Matest, is used to simulate and reproduce the real compaction conditions under actual road paving operations, hence determining the compaction properties of the asphalt. Such compaction is achieved in a fully automatic way, by combining the rotary action and the vertical resultant force applied by a mechanical head. The Compactor comprises a highly rigid steel frame ensuring excellent angle control. Load is applied by an electro-pneumatic cylinder, servo-controlled by a precision pressure regulator; the height is measured by a linear transducer.

This test, developed in laboratory, consists in evaluating the deformation (rut) depth of a bituminous mixture subjected to cycles of passes of a loaded rubber wheel under constant and controlled temperature conditions. To perform the test, a wheel tracking apparatus is used to simulate the effect of traffic and to measure the deformation susceptibility of the bituminous sample.

Technical specifications:

  • The machine fully satisfies both EN 12697-22 and BS 598:110 Specifications.
  • Travel of the table: 230 /- 5 mm
  • Table cycle frequency: adjustable 15 to 40 cycles per minute.
  • Hard rubber tyred wheel having outside diameter 200 mm
  • Wheel load on the sample: 700N /-10N (EN 12697-22) or 520N (BS 598:110). The load is applied on the sample through a lever.
  • The effective load applied on the sample can be adjusted by micrometrical weights positioning.
  • Continuous real time rut depth measurement (penetration of the wheel into the sample) through a linear transducer 40 mm travel by 0,01 mm accuracy.
  • The test frame is made of robust aluminium alloy and it is contained in a climatic cabinet with adjustable temperature from 30 to 65°C. /- 1.0°C.
  • The cabinet is equipped with two doors with insulated glass for inspection
  • The sample table has dimensions: 400 x 390 mm and can accept rectangular slabs of several

Sizes:

  • 305 x 305 mm, 50 or 100 mm high
  • 305 x 400 mm, 50 or 100 mm high
  • 200 mm dia. core samples, 50 mm high
  • The sample confinement frames are not included and have to be ordered separately (see accessories)

Pressure Ageing Vesell (PAV’s) use heated, pressurized air to simulate long-term oxidative aging of asphalt binders. The PAV's consist of an ASME-Code and CE certified stainless steel pressure vessel, stainless steel cabinet with encased band heaters, and integral pressure measurement control. The state of the art PAV3 meets ASTM, AASHTO, and EN 14769 requirements and includes a platinum RTD device to insure accurate temperature resolu- tion and uniformity. A pressure relief valve and high-temperature thermal shut-down are included as standard safety features. A USB port located on the front of the unit allows the user to easily store test data and upgrade software if necessary. The system now includes remote operation capabili- ties, and allows the user to completely control the PAV3 system using an app compatible with most smart phones and tablets. The Pressure Aging Vessel (PAV3) uses a Touch-Screen Controller with front panel user interface for complete control and monitoring of all test processes. The system has an operating pressure range of 2.1 ±0.1mPa, and temperature range of 80°—115°C, with resolution of 0.1°C. This easy-to-use system completes a test in three easy steps: press the heat button, insert specimens when prompted, and press the age button. The stainless steel cabinet measures 28x18x30in (710x460x760mm), WxDxH. The PAV includes a set of ten TFOT specimen pans, a precision anodized aluminum sample holder with lifting handle, and a specimen handling tool.
