HYRS-6 combustion method asphalt content analyzer

1、 HYRS-6 Combustion Method Asphalt Content Tester Product Introduction: The combustion furnace produced by our company meets the technical requirements of Chinese transportation industry standard JT/T671-2006, American standard ASTM D6307-98, and AASHTO T308-99. It can accurately and stably determine the asphalt content in asphalt mixtures, and can meet the requirements of large-scale continuous production in mixing plants, highway supervision, and research units

2. Main features of the combustion method asphalt content analyzer:

1、 The combustion furnace body is made of aerospace insulation materials, with short preheating time and suitable heating rate. It can reach the standard working temperature of 538 ℃ within 20 minutes, which greatly saves testing time compared to similar products

2、 Good insulation performance, when the internal temperature of the furnace reaches the standard working temperature, the external temperature of the furnace is below 45 ℃, and the operation is safe. At the same time, the effect is excellent, avoiding the influence of high temperature on the accuracy of the electronic scale

3、 It has the function of secondary combustion in the rear combustion chamber, as well as high-temperature filtration and exhaust system, to protect the emission of test exhaust gas to meet environmental requirements

4、 The instrument runs automatically and is easy to operate. Simply input the sample weight and calibration coefficient, load the sample, press the work button, and the data will be automatically printed after the experiment is completed

5、 The software has excellent functions and can simultaneously display asphalt content, oil stone ratio, sample weight loss, and test time

6、 Using a purchase balance to ensure accurate measurement

The two important substances in asphalt mixtures are asphalt and aggregates. Therefore, accurate determination of asphalt percentage (% AC) and aggregate content is an important protection for controlling the quality of HMA. Therefore, solvent extraction method has been widely used to determine the asphalt content in asphalt mixtures. However, the solvent extraction method uses toxic solvents and has a long testing time, which cannot meet the requirements of large-scale continuous production in mixing plants and highway supervision inspections. The use of combustion method to determine asphalt content has a short testing time, is clean, and only emits a small amount of smoke and carbon dioxide. It can be tested continuously and meets the requirements of large-scale continuous production in mixing plants and highway supervision

More and more people are realizing the importance of environmental protection and the harm of solvent extraction method to the environment and workers. It is gradually recommended to use combustion method instead of solvent extraction method. Therefore, the combustion method asphalt content analyzer is an equipment that will be widely used in highway construction. According to some research institutions' published papers, the combustion method has higher accuracy in measuring asphalt content compared to the solvent extraction method
