Description
Technical Field
The utility model relates to a test instrument uses technical field, especially relates to a rubber asphalt segregation test device.
Background
The rubber asphalt is a modified asphalt cementing material, is also called polymer modified asphalt, and is widely applied to highway construction at home and abroad. However, the density, viscosity, molecular weight, polarity and solubility parameters of the polymer and the asphalt are greatly different, and the polymer and the asphalt are incompatible with each other from the thermodynamic analysis. Polymers often spontaneously agglomerate and segregate in the base asphalt. Therefore, the storage stability of polymer modified asphalt is a key issue that must be solved in scientific research and practical production.
At present, the storage stability of the modified asphalt is mainly evaluated by adopting an isolation test. According to the road engineering asphalt and asphalt mixture test procedures (JTJ052-2000) and ASTM (ASTM D5976 and D5892) in China, modified asphalt is put into a test mold, placed for a period of time under a high-temperature condition, then samples are respectively taken from the top and the bottom (some samples are divided into an upper part, a middle part and a lower part) of the test mold, and the difference of softening points of the samples is measured to evaluate the isolation degree of the polymer modified asphalt. China's specification (JTJ036-98) stipulates that the difference between the upper and lower softening points is less than 2.5 ℃, and the product is qualified. The test procedures specified by the specifications are as follows:
(1) the test mold can be an aluminum tube or a glass tube, and one section of the test mold is provided with an opening;
(2) weighing 50 g of asphalt sample, and closing the opening end;
(3) standing the test mould in an oven at 163 +/-5 ℃ for 48 +/-1 h;
(4) taking out the test mold from the oven, and placing the test mold into a refrigerator of a household refrigerator for standing for 4 hours;
(5) if the sample is an aluminum tube, placing the aluminum tube on a solid flat plate, and cutting the aluminum tube containing the sample into three equally divided sections by using a knife; in the case of a glass tube, the glass is gently broken with a small hammer and the clean asphalt sample is cut into three equally divided sections. Respectively placing the upper end and the lower end into beakers, standing the beakers in an oven at 163 +/-5 ℃ and heating until the sample can sufficiently flow;
(6) and placing the upper section sample and the lower end sample on the same softening point tester to simultaneously perform softening point measurement.
The segregation test of the modified asphalt is an important evaluation method for evaluating the storage stability of the modified asphalt.
However, the sample holding tube has strict requirements of standing, stability and no shaking for the whole storage stability evaluation test of nearly 50 hours in the current standard requirements. The sample containing pipe is held by hands to move, so that the requirement of keeping the sample containing pipe upright, stable and free from shaking is difficult to achieve.
