Summary
The instrument is designed and made as per T0719-2011 "Bituminous Mixtures Wheel-track Test" in the Industry Standard of People's Republic of china JTG E20-2011 "Highway Engineering Bitumen and Bituminous Mixtures Test Code ".It is suitable to determine the wheel-track against capability of bituminous mixtures in the high temperature .And it is also can be used to determine the stability in the high temperature of bituminous mixtures on site .
I.Main technical characteristics
1.The instrument can automatic control temperature ,automatic generate ,save test results ;It is convenient to call history data and print out test report .
2.It adopts absolute temperature sensor ,long time no temperature drift test .The range of temperature controlling is wide ,high accuracy and good stability .
3.Test machine and constant temperature box adopts a kind of all-in-one machine ,and inner box adopts air circulation ,high accuracy .Stable operation and no noise .
4.It adopts high displacement sensor ,The precision is more than +0.05mm . Data collection has high resolution and fast speed .
5.The computer and touch-screen can be controlled independently .
6.The instrument can preheat three samples at the same time .
II.Advantage of the control software
1.Non standard function : set time and temperature at random .
2.Real-time display time ,placement deformation and time ,temperature curve .
3.It can display compaction time and times .
4.It can calculate automatically and print wheel-track stability value .
5.Software can calibrate accuracy to placement sensor and temperature sensor .
6.The device has functions of self-diagnostic ,and display fault-code to ensure the stable operation
