Product Price :Get Latest PriceThe equipment is used to rapidly determine the asphalt content, bulk specific gravity of aggregates, the specific gravity of bituminous compacted road mixtures and the percent air voids in the sample. Vacuum pump must be ordered separately.
Product Price :Get Latest PriceUsed 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.
Product Price :Get Latest PricePressure 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.
Product Price :Get Latest PriceMarshall Apparatus is used for the measurement of the resistance to plastic flow of cylindrical specimens of bituminous paving mixture loaded on the lateral surface.
Product Price :Get Latest PriceThe frame is provided of two fix speed ranges, easily selectable ,1,27 mm/min. for CBR tests 50,8 mm/min for Marshall tests.
Product Price :Get Latest PriceThe Automatic Compactor eliminates the laborious process of manual compaction and an even degree of compaction is achieved. The driven mechanism lifts the weight of 4.5kg and drops it through a correct height of 457 mm. The rammer foot is removable, which facilitates preheating. A compaction pedestal with specimen holder is fixed to the base. An Automatic Blow counter enables the number of blows to be present before each test and automatically stops the machine on completion. Suitable for operation on 230 V, 50 Hz, Single Phase, A.C. supply.
Product Price :Get Latest PriceThis 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.
Product Price :Get Latest PriceThis 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.
