Asphalt Content Tester(Combustion Furnace Method)

Summary
The instrument is designed and made as per T0735-2011 “Asphalt Content Test in Bituminous Mixtures ( Combustion Furnace Method )”in JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. The instrument can determine asphalt content rapidly, correctly, safely and reliably .And it is suitable to determine the asphalt content of the bituminous mixtures .It is also used to analysis the asphalt mixtures after the combustion .
The instrument is also as per requirements of ASTM D 6307-98 and AASHTO T308-99 .

I.Main technical features

1. The body of the combustion furnace adopts aerospace insulation materials .It has good warm-keeping effect and short preheating time .The heating rate is rapid and it can arrive to standard temperature 538℃ in the 30 minutes .
2. It has good heat insulation characteristic ,when the inner of the furnace body arrives to the standard temperature , the temperature of outer furnace body will be lower than 45℃ ,and it has high operation safety ,for avoid the influence of the high temperature on the electronic scales measurement accuracy .
3. It adopts the second combustion function and high temperature filtration technology .The test exhaust emission reach the standard .
4. The function of the software is powerful .It can display temperature ,sample weight ,weight loss ,correction coefficient ,asphalt content and asphalt aggregate ratio .
5. The temperature adopts fuzzy control plan ,the temperature controlling accuracy is high and it has good stability .
6. 
   Safety protection ,no use organic solvent that can damage the human’s  healthy and environment ,it is a green product .
7. It adopts special structure .and ensure not to produce state error in the high temperature at the key measuring site .
8. 7inch industrial stage touch-screen .and the screen display large information ,operation is simple and convenient ,the work is reliable .Put the sample into the furnace and close the furnace door ,press the open key ,the instrument can be finished the determination automatically.
9. Real-time display test procedure data ,and it has self diagnostic function ,fault code indication function ,it can inquire about the history data and deal with it .
10. After the test finished ,the instrument has voice indication function and it can save and print out the test results .
11. The processing mode is flexible ,it can choose the software and hardware as accessories, it can connect with computer and common printer .It can use the USB drives to download the data and connect with the network function of the wet .
