Introduction

Standard Name: Standard Practice for Assessment of Ground Reference Data for Transverse Pavement Profiling System Assessment

Standard Number: AASHTO PP 110-231

Scope:

• This practice outlines the procedures used to assess ground reference data utilized in PP 109.
• It describes the accuracy and precision analysis required to ensure that a ground reference equipment (GRE) system collects acceptable quality ground reference data.
• The accuracy and precision are evaluated using four surfaces: a certified straight edge, a bounding beam with gauge blocks, a road surface, and a macrotexture surface.
• Measures evaluated include transverse, longitudinal, and vertical measurement error; transverse, longitudinal, and vertical measurement spacing; transverse straightness; and horizontal plane flatness.
• It is necessary for all four surfaces to be measured and analyzed to ensure the GRE is capable of producing accurate road surface measurements.
