路面材料强度试验仪规范解读

Interpretation of the Specifications for Pavement Material Strength Testers

路面材料强度试验仪是一种多功能的公路路基材料实验仪器,其计量量值的准确可靠程度直接关系到铁路、公路、大型建筑的工程质量与可靠性。介绍了安徽省地方校准规范《路面材料强度试验仪》的起草背景和编制思路,详细地介绍了路面材料试验仪计量性能的提出、技术要求的确定、校准设备的选择、力值和速率不确定度评定,给出了校准条件和校准用设备,确定了校准项目和校准方法,并对硬度和同轴度等校准项目的删减进行了说明,为路面材料强度试验仪工作开展提供了参考。

Pavement material strength tester is a multifunctional experimental instrument for highway roadbed materials,and the accuracy and reliability of its measurement value is directly related to the engineering quality and reliability of railways,highways,and large buildings.The drafting background and compilation idea of the local calibration“Pavement Material Strength Tester”in Anhui Province are introduced.The proposal of measurement performance the determination of technical requirements,the selection of calibration equipment,the force value and the rate of uncertainty assessment of the pavement material tester are described in detail,gives the calibration conditions and equipment for calibration are given,the calibration items and the calibration method are determined,and the deletion of calibration items such as hardness and coaxiality and other calibration items are explained,which provides reference for the work of pavement material strength tester.
