燃烧法沥青含量测试仪测量不确定度评定

Measurement Uncertainty about Testing Apparatus for Asphalt Content by Burning Method

燃烧法沥青含量测试仪是混合料沥青含量分析的主要设备,根据试验方法可以有效测量混合料中沥青的含量,对混合料质量监控具有重要意义。燃烧法沥青含量测试仪检定主要参照JJG(交通)072-2006燃烧法沥青含量测试仪检定规程。本文通过分析,针对燃烧法沥青含量测试仪的温度示值误差、电子天平质量称重误差两个参数的测量不确定度进行了详细的分析和评定,对其他类似仪器测量不确定度评定有一定的参考意义。

Testing apparatus for asphalt content by burning method is the main equipment for asphalt content analysis.According to the test method,the asphalt content in the mixture can be measured effectively.Testing apparatus is of great significance to the quality control of mixture.The verification of equipment mainly refers to JJG(traffic)072-2006 verification regulation of Testing apparatus for asphalt content by burning method.This paper analyzes and evaluates the measurement uncertainty of temperature indication error and weighing error.This paper has certain reference significance for the evaluation of measurement uncertainty of other similar instruments.
