Abstract

The invention relates to the field of asphalt detection equipment, in particular to heating and sorting equipment used in the process of detecting the asphalt content through a combustion method. The invention aims to improve the asphalt content detection efficiency and the precision of the detection result at the present stage. The device comprises an asphalt detection furnace, a discharge port of a hoisting mechanism is located at an inlet of the asphalt detection furnace, the inlet is located at an outlet of a pilot detection device, the pilot detection device comprises a feeding platform, and the feeding platform is provided with a square assembly line and a power element for driving the assembly line to operate. A drying mechanism, a heating mechanism, a uniform smearing mechanism and an observation mechanism through which a test block table can pass are sequentially arranged along the direction of the assembly line, and the test block table comprises a square platform and a cylindrical test block basket mounted on the square platform. The method has the advantages that the pilot step is preset in front of the detection furnace, so that a more accurate detection result and higher detection efficiency are provided.

Description

technical field [0001] The invention relates to the field of asphalt detection equipment, in particular to heating and sorting equipment used in the process of detecting asphalt content by combustion method. Background technique [0002] Combustion method to measure asphalt binder content in hot mix asphalt mixture is to put the hot mix asphalt mixture into a combustion furnace at 538 ℃, and the asphalt binder is burned. The bitumen content in the mixture can be calculated according to the mass difference of the mixture before and after combustion. [0003] During the combustion test, some mass (usually less than 0.4%) is usually lost for most mineral materials. The measured mass loss of the hot mix asphalt mixture during the combustion test consists of the mass loss of the asphalt binder and the mass loss of the aggregate. The mass loss of the asphalt binder is obtained by subtracting the mass loss of the aggregate from the measured total mass loss. According to the mass...
