This instrument is in accordance with the industry standards of the People's Republic of China JTG E20-2011《 Test Regulations for Asphalt and Asphalt Mixture in Highway Engineering T0735-2011《 Test of asphalt content in asphalt mixture (combustion furnace method) and JT/T 671-2006《 Designed and manufactured as required by the combustion method asphalt content tester. This instrument can quickly, accurately, safely and reliably determine the asphalt content. It is suitable for measuring the asphalt content in asphalt mixture, and also for screening and analysis of the burned asphalt mixture. It is an ideal instrument for detecting the asphalt content in units of production, research, and use of asphalt mixtures.
This instrument also meets the ASTM D 6307-98 standard, AASHTO T308-99 Standard technical requirements.

1. Main technical characteristics
1、Use a microcontroller and high-precision electronic balance for testing and control, which is simple to operate and easy to learn and easy to use and maintain.
2、Use a microcontroller and high-precision electronic balance to measure the weight change of the sample, and accurately determine the test end point according to the pre-set test stability value.
3、The new furnace body structure is adopted, the heating speed is fast and the test time is short.
4、New appearance design, the furnace body has a beautiful appearance. The furnace body and balance chassis are positioned accurately to ensure that the sample center is located in the center of the balance.
5、The asphalt content can be measured quickly, accurately, safely and reliably, and can meet the requirements of large-scale continuous production of mixing stations and highway supervision inspection.
6、After the test is completed, the printing file will be automatically formed and the printer will automatically print the test report.
