Embodiment Construction
[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1-2 As shown, a sample preparation device for asphalt dynamic viscosity test includes a rear frame body 1, a front frame body 2, and both ends of the rear frame body 1 and the front frame body 2 are respectively connected by a set of connecting parts 3; An observation channel is formed between 1 and the front frame body 2. During production, the rear frame body 1, the front frame body 2 and the connecting part 3 are all welded by high temperature resistant stainless steel with a thickness of 2mm-4mm, which has good stability. It can also be made of other high temperature resistant materials, as long as the materials are strong and durable; the distance between the connecting part 3 and the bottom of the front frame body 2 and the rear frame body 1 is controlled between 120mm-130mm.
[0026] The rear frame body 1 is ...

The invention discloses a sample preparation device for an asphalt dynamic viscosity test, which belongs to the technical field of asphalt detection, and aims at solving the problems that when asphaltis injected into a capillary viscometer, the asphalt is not easily and accurately controlled on scale marks, and time and labor are wasted. The device comprises a rear frame body and a front frame body, wherein the two ends of the rear frame body and the two ends of the front frame body are connected through a group of connecting parts; the rear frame body is stepped, a third reflector is obliquely arranged at the top of the rear frame body, and a first reflector is obliquely arranged at the lower step of the rear frame body; a second reflector is arranged at the upper part of the front framebody, is parallel to the third reflector in the horizontal direction, and is parallel to the first reflector in the vertical direction. The device is simple in structure and convenient to manufacture, sample preparation and testing of an asphalt dynamic viscosity test can be independently, effectively and rapidly completed by one person, manpower is greatly saved, and the testing efficiency and the accuracy of a testing result are improved.
Description
technical field [0001] The invention belongs to the technical field of asphalt detection, and in particular relates to a sample preparation device for asphalt dynamic viscosity test. Background technique [0002] Asphalt dynamic viscosity is one of the main indicators of asphalt properties, reflecting an important parameter of road asphalt resistance to permanent deformation at high temperature. There are two main test methods, namely Brookfield rotational viscometer method and vacuum decompression capillary method. The use of vacuum decompression capillary method to test the dynamic viscosity of viscous petroleum asphalt is a key test for asphalt technical requirements, and the vacuum decompression capillary method is basically adopted internationally for 60 ℃ viscosity classification. [0003] At present, my country's current "Asphalt and Asphalt Mixture Test Regulations for Highway Engineering" stipulates that the dynamic viscosity test of asphalt (vacuum decompression ca...
