JSC BSKB Neftekhimavtomatika EN 12697-33 developed a set of laboratory equipment for test of asphalt concrete on a koleeobrazovaniye according to PNST, EN 12697-22 (the small car) also. Installation for consolidation of asphalt concrete mixes a smooth steel skating rink "Lintel of SP-20" and installation for definition of a koleeobrazovaniye "Lintel of KNK-20" is a part of a set.
The SP-20 installation is intended for preparation of tests of asphalt concrete for the purpose of their subsequent test on a koleeobrazovaniye on KNK-20. It provides in vitro the maximum approach of processes of consolidation of asphalt concrete mix to consolidation conditions by means of road skating rinks due to control of pressure and speed of movement of steel sector on a sample.
The KNK-20 installation provides simultaneous test of two samples and imitates process of deformation of pavings under the influence of repeated loadings of vehicles. Test is carried out in the automatic mode, the report of the established form is issued, transfer of results of tests on a radio channel to the labotorno-information Lintel-Lys system is provided.
Car design monoblock, floor type. As the control panel the personal computer with the touch display 17 is used".
Automatic KNK-20 installation functions:
- maintenance of stable temperature in a test chamber;
- automatic supply of wheels from parking spaces to a surface of samples;
- task and continuous control of effort of a clip of wheels;
- control of depth of a track in real time in 25 points with display on the display;
- stop on performance of the set quantity of motion cycles of a wheel or on reaching the set track depth;
- storage in the database, a possibility of viewing and the press on the printer in the form of reports
- to 200 results of tests;
- calculation of characteristics (average coefficient of increase in depth of a trace of TR, increase in depth of a track in the material WTR, etc.) by several results;
- automatic transfer of results of tests from the device to the personal computer through a subsystem of the wireless Lintel-Link interface in the laboratory and information Lintel-Lys system.
