Questionnaire for Implementation of Mechanistic Empirical Pavement Design Guide (MEPDG)
Burden Statement
This collection of information is voluntary and will be used to assess the status of pavement design practice and plans Nationwide. This information will allow State Transportation Agencies (STAs) and the Federal Highway Administration (FHWA) optimize allocation of their resources for the most efficient pursuit of implementation of the Mechanistic-Empirical Pavement Design Guide (MEPDG).
It should take about 2 hours to respond to this survey, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and returning the survey. No sensitive information is being collected in this survey and no names will be included in the reporting of the survey results. Please note that an agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control number for this collection is 2125-XXXX (state OMB #, and the approval period will expire XXXXXXXX.
Instructions
Questions are numbered and divided per topical section. Answer choices for each question are in brackets. Please note that when the acronym MEPDG is used, it pertains to the most recent version of the NCHRP 1-37A documentation and software product specifically.
PLEASE NOTE THAT THIS VERSION IS IN DRAFT SO THAT IT CAN BE REVIEWED FOR TECHNICAL CONTENT. FURTHER FORMATTING AND CONVERSION TO ONLINE WEB FORMAT WILL OCCUR AFTER OMB APPROVAL.
