AASHTO R 87-18 PDF Download

AASHTO R 87-18 is a standard practice for determining pavement deformation parameters and cross slope from collected transverse profiles. This standard provides guidelines for calculating parameters such as rut depth and cross slope using the data obtained from transverse profiles of the pavement surface.

The standard does not specify the specific equipment or software that should be used for the calculations. Instead, it allows for any approach that can be validated to meet the requirements outlined in the standard. This flexibility is intended to encourage innovation and prevent unnecessary restrictions on new methods.

The main goal of AASHTO R 87-18 is to establish a level of standardization that ensures consistent and accurate estimation of pavement condition. By providing guidelines for determining deformation parameters and cross slope, the standard aims to improve the quality and reliability of pavement condition estimates.
