A128N - ACCELERATED POLISHING MACHINE - MATEST PRODUCTION

DETERMINATION OF THE POLISHED STONE VALUE
It measures the resistance of road aggregates to the polishing action of vehicle tyres on a road surface, paving stones and paving blocks. The specimens are manufactured with suitable moulds.
The specimen is than located on the Road Wheel accepting 14 specimens.
The wheel is now rotated and enters in contact with solid rubber tyre, spring loaded. Abrasive charges are continuously fed by mechanical feeders at fixed speed.
Road wheel speed: 310 to 330 r.p.m.
The flour emery is loaded on to the specimen through a suitable opening. The water is supplied at a controlled rate through a water container.
The digital control panel, foreseen in the back side of the machine, allows to select the test time.
During the test execution the display shows the remaining time and the speed rotation of the wheel holding the specimens.
The machine provides a method of preparing polished stone specimens for use with the Skid Resistance Tester mod. A113 when used in Laboratory.
The unit is supplied complete with 2 rubber wheels (one for corn and one for flour emery), set of 4 secimen moulds and 2 mould covers, while control stone, corn and flour emery have to be ordered separately (see accessories). Power supply: 230 V 50 Hz 1ph 750W

B039 - ROLLER COMPACTOR

This Roller Compactor entirely developed and manufactured by Matest is used to produce representative sample slabs of several dimensions of bituminous mixtures laid and compacted in the roads.
The compaction is performed through a segmented roller with alternated operated rotation simulating the on-site action of a street roller.
Slabs are compacted up to the selected density and are then compatible for rut tests with B038 Matest Wheel Tracker.
The slabs can also be cored or cut off to obtain cylinders and beams for bending fatigue, indirect tensile, static and dynamic creep, stiffness, 4-point tests, etc.


THE ROLLER COMPACTOR CONSISTS OF:
- Sturdy steel frame, mould support table with alternating displacement system, for table displacement and vertical load pressure
- Electronic control unit with touch screen colour display, that runs like a standard PC based on Windows operating system for the management and analysis of the data, test results, graphs. The touch-screen icon interface allows an easy set up of the parameters and immediate execution of the test. Direct connection to Intranet (connection to a LAN network) and Internet to establish a remote communication and receive an immediate diagnostic analysis of the potential problem from Matest technicians, or for updates  of the software.

Unlimited memory storage with: 2 USB ports, 1 SD card slot , RS232/485 serial port.
Three transducers are installed to manage the roller and table displacements and vertical load pressure.
The compaction cycle can be programmed by aiming a certain load or deformation value.
When deformation value is programmed, the system automatically programs the suitable loads to obtain the selected final thickness.
The flexibility of the program grants the production of samples with uniform density and dimensions, fully meeting Standards Spec. and Research requirements.
A friendly and easy to use interface allows an immediate and fully automatic test execution, data acquisition and processing, Test Report and file.
