摘要近年以来，公路建设逐渐成为国家经济发展的重中之重，沥青的使用量也逐渐的增大。在沥青公路施工现场中，沥青是必须要用到的，所以必须对沥青的使用量进行计量。为此开发一个测量精度高、使用方法简单、性价比高的沥青自动计量系统，对我国沥青行业具有十分重要的意义。但是，由于沥青的特点与性质，使得其计量问题长时间没有解决，其测量精确度也存在着问题。因此，提高沥青计量的精确度，实现沥青的连续快速计量成为未来发展的重要领域。39206

对比流体的基本性质特征不难发现沥青在计量阶段处于流体的状态。通常状态下，沥青拥有正常流体所拥有的性质，并与流体的流动规律和基本原理相符合。具备了流体所应具备的一切性质，同时它也符合了流体的流动规律和基本原理。首先对计量系统的种类进行了分析，比较了各系统之间的优缺点，对设备的使用要求也进行了大量论证介绍，最重要的是介绍了处于连续计量系统中混合料的流体动力学分析。

Abstract
In recent years, has gradually become the top priority of national economic development, highway construction of asphalt usage also gradually increased. At the scene of the asphalt road construction, the asphalt is to be used, so asphalt usage must be measured. To develop a high precision measurement, use method is simple, high ratio of automatic measurement system of asphalt, asphalt industry is of great significance to our country. However, due to the characteristics and properties of asphalt, making the measurement problem for a long time not solve, its measuring accuracy and there is a problem. As a result, improve the accuracy of the asphalt measuring, realize the continuous rapid measurement in the future development of asphalt important areas.
To compare the basic properties of fluid is not hard to find asphalt in the measurement phase is in a state of fluid. Usually state, the properties of asphalt have normal fluid have with fluid flow law and basic principle. Have all the properties of the fluid should have, at the same time it also conforms to the law of fluid flow and the basic principle. First of all the types of measuring system are analyzed, and compared the advantages and disadvantages of the system, a lot of arguments on the use of equipment requirements are also introduced, and the most important thing is in a continuous measurement system are introduced in the mixture of fluid dynamics analysis.
