Testing Procedure Manual

The Testing Procedures Committee is charged with the responsibility for the creation and revision of all DOTD Testing and Reporting procedures. The committee is made up of representatives from the Materials and Testing Section, the District Laboratories, Technology Transfer and Training, Contracts and Specifications, the Construction Division, and the Federal Highway Administration. The chairman of the committee is the Materials Engineer Administrator.


The Materials Qualifications Unit is responsible for the publication of the Testing Procedures Manual.

The Testing Procedures Manual gives the DOTD testing and reporting procedures which ensure consistency and accuracy in the Department's Quality Assurance Program. These procedures are utilized when testing materials related to DOTD construction and maintenance activities. All DOTD TR procedures are approved by the FHWA for use on federally funded projects.

Foreward

The purpose of this manual is to standardize the testing procedures used throughout the State by the various laboratories.

 

All testing methods shall be in accordance with the following publications unless otherwise stated in the Standard Specifications, plans, or project specifications. Precedence shall be in the order as written:

  • First - Louisiana Department of Transportation and Development (DOTD) Testing Procedures Manual,
  • Second - Standards published by the American Association of State Highway and Transportation Officials (AASHTO),
  • Third - Standards published by the American Society for Testing and Materials (ASTM).

 

This manual is divided into two volumes and each volume is divided into parts. Volume I contains test methods pertinent to aggregates, concrete, and bituminous materials. Volume II contains test methods pertinent to soils, chemicals, miscellaneous materials, and adhesives. Each part is further arranged with the test methods for that part listed in numerical order. The year of adoption or last revision of the test method is indicated by the two digits following the number of the test method.

This manual is primarily for use by the Louisiana Department of Transportation​​​ and Development. Inquiries should be directed to the Materials Qualifications Unit of the Materials and Testing Section, 225-248-4165, or e-mail [email protected].
In case of ambiguity or difficulty in the interpretation of testing procedures, the Materials and Testing Section should be consulted.
