Problems solved by technology
The existing asphalt performance detection test device makes the asphalt test block installed on the base move along the guide rail, thereby driving the rubber wheel to roll the asphalt test block, and measures the asphalt binder according to the stress and strain of the asphalt test block. performance, but because the performance of asphalt is not exactly the same under different pressures, rut widths and wheel toughness, it is necessary to conduct tests according to the road conditions of asphalt application. The existing experimental equipment needs to replace various wheels for repeated tests to obtain Relevant data, it is troublesome to disassemble the whole process of the test, many control groups are needed, and it takes a long time

Description
technical field [0001] The invention relates to the technical field of a road material testing device, in particular to an asphalt performance testing device for municipal engineering. Background technique [0002] Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement caused by traffic and natural factors, making the pavement smooth and less dusty and durable. durable. The addition of different aggregates and different contents into the asphalt binder will have different effects on the performance of the asphalt pavement. In order to obtain an asphalt binder with good performance at the test site, it is necessary to evaluate the performance of the asphalt binder with different components. detection test. The existing asphalt performance detection test device makes the asphalt test block installed on the base move along th...
