题目:沥青八字模检定参数

一、

沥青八字模是用于检验沥青路面抗滑性能的装置,其检定参数包括几何尺寸、质量、材料性能等。本文将详细介绍沥青八字模检定参数,以确保其精度和可靠性。

二、几何尺寸检定

1. 模具尺寸

沥青八字模的尺寸应符合相关标准要求。常见规格的沥青八字模为200×200×80mm,其中200mm为模具长度,200mm为模具宽度,80mm为模具高度。

2. 槽宽与槽深

沥青八字模中应有若干个等宽等深的槽,槽宽和槽深应符合相关标准要求。常见规格的沥青八字模的槽宽为10mm,槽深为5mm。

3. 槽间距

沥青八字模中槽间距应符合相关标准要求。常见规格的沥青八字模的槽间距为20mm。

三、质量检定

1. 重量

沥青八字模的重量应符合相关标准要求。常见规格的沥青八字模的重量约为2.5kg。

2. 强度

沥青八字模的强度应满足使用要求。沥青八字模应能够承受沥青混合料的挤压和振动,而不产生损坏。

四、材料性能检定

1. 材料类型

沥青八字模应采用符合相关标准要求的材料制造。常见规格的沥青八字模采用铝合金或铸铁等材料制造。

2. 表面光洁度

沥青八字模的表面应光滑平整,无毛刺、划痕等缺陷。表面光洁度应符合相关标准要求。

3. 耐腐蚀性

沥青八字模应具有良好的耐腐蚀性,能够承受沥青混合料中酸、碱等物质的腐蚀。耐腐蚀性应符合相关标准要求。

五、

沥青八字模检定参数的准确性和可靠性对沥青路面抗滑性能的检验具有重要意义。通过对沥青八字模的几何尺寸、质量、材料性能等参数进行检定,可以确保沥青八字模的精度和可靠性,为沥青路面抗滑性能的检验提供准确可靠的数据。
