Improvements to Ride Specifications

Project Summary

The purpose of this research project is to develop an objective, rational, economically and financially justifiable ride pay adjustment system that incorporates "new" versus "existing" ride quality and a methodology to tailor the existing techniques to measure ride quality using Surface Test Type B or inertial profilers on short projects. The objective of this research is to develop a comprehensive database that links TxDOT’s SiteManager. Design and Construction Information System (DCIS) and Pavement Management Information System (PMIS) databases. To better understand the practical issues associated with ride measurement on short projects, the research team will develop a survey questionnaire with specific and direct questions that will be sent over to relevant TxDOT personnel and non-TxDOT subject matter experts. The survey will identify the main issues that are associated with ride measurements on short projects. As needed, iii-person or over-the-phone interviews will also be executed by the research team. Subsequently, the research team will investigate different ways to measure ride quality on short project segments and recommend procedures to calculate ride using inertial profilers or Surface Test type B. A field experiment will be conducted to verify the recommended procedures and to identify any practical issues while implementing the proposed methods. The deliverables of this research will improve the existing pay adjustment factors and the evaluation of roughness measurements on short projects used by TxDOT.
