The Ira B. Mullis Papers contains correspondence, reports, memos, Mullis' professional writings, photographs, blueprints, maps, charts and notes, documenting Mullis's career as a civil engineer engaged in road design and construction. Materials in the collection date from 1925 to 1964.
Ira B. Mullis (1877-1968) was a professional civil engineer engaged in the practical and theoretical aspects of road and roadbed design, construction and maintenance in the United States from 1904 to 1964.
Born in Wingate, North Carolina, on August 29, 1877, Ira Broadus Mullis spent the whole of his professional career (1904-1956) as a civil engineer engaged in road construction and design. He specialized in the materials, techniques, maintenance and design of roadbeds, bringing to this field a personal interest in geology as well as engineering. Mullis graduated from Wingate College and then attended North Carolina State College, now North Carolina State University, from 1903 to 1904 until the death of his father, and the subsequent financial hardship, forced him to leave without graduating in order to pursue a professional career as a civil engineer.
Mullis spent the early part of his career, from 1904 to 1920, in North Carolina serving as the City Engineer for Lumberton, North Carolina (1910-1913) and, under the direction of Joseph Hyde Pratt, as a Highway Engineer for the North Carolina Geological and Economic Survey (1913-1915) and the North Carolina Highway Commission (1915-1918).
From 1920 until 1940, Mullis worked for the United States Bureau of Public Roads, first as a Testing Engineer based in Washington, D.C. (1920-1931) and then as a Highway Engineer (1931-1942) based in the Midwest. Mullis's district, District 5, encompassed Iowa, Kansas, Missouri and Nebraska. His duties included the supervision of road and bridge construction in the district, road location and inspection, examination of pavement and roadbed failures and the development of specifications for adequate roadbed compaction. He left the Bureau of Public Roads in January 1942, and moved to Raleigh, North Carolina, to work for two Raleigh-based firms, Southern Aggregates Corporation and the engineering firm of Pratt, Lassiter and Watkins. He retired in 1956 at the age of 79.
Mullis had several papers published in the Proceedings of the American Society of Civil Engineers between 1938 and 1963, and retained a lifelong interest in roadbed design, construction and maintenance.
Mullis's parents were Daniel Wilson Mullis and Hallie Clementine Williams. Mullis married Annie Barbara Duckett (1890-1966) on April 18, 1917. They had one child, a son, Ira Broadus Mullis Jr. (1921-2000). Mullis died on November 3, 1968.
This collection documents the professional career of Ira B. Mullis as a civil engineer working on road and roadbed design, construction and maintenance from 1925 to 1964. Correspondence and Professional Writings form the bulk of the collection and provide detailed information about the day to day duties of an engineer working for the United States Bureau of Public Roads in the form of memos, reports, articles, papers and letters, as well as material on his tenure as a consulting engineer for two private Raleigh, North Carolina-based companies-- Southern Aggregates Corporation and Pratt, Lassiter and Watkins. Biographical information can be found in the Correspondence series but the collection contains few items of a strictly personal nature. Other types of materials found in the collection include photographs, blueprints and maps.
The Ira B. Mullis Papers are organized into five series: Correspondence, Professional Writings, Research Notes, Road Compacting Equipment Promotional Material, and Miscellaneous Material.

Donated by Ira B. Mullis in 1967 (Accession no. 1967-0001).
Processed by Joel Mauger and Michael Watts; Encoded by Michael Watts.
The collection is organized into five principal series:
Mullis's correspondence is almost entirely of a professional nature as even the most personal items contain mention of his career or publications. Included in this series are items such as internal reports from the Bureau of Public Roads, extensive biographical outlines, letters to North Carolina representatives and senators and engineering faculty members at North Carolina State College. An extensive correspondence, written from 1939 to 1942, with Robert G. Lassiter of Southern Aggregates and Joseph Hyde Pratt, a well known professor of geology and engineering at the University of North Carolina in Chapel Hill, details Mullis's attempts to obtain a cooperative placement at North Carolina State College under the auspices of the Bureau of Public Roads and the Department of Engineering. Almost all outgoing correspondence is in the form of typewritten carbon copies, while incoming correspondence is in the form of signed originals. Some third party correspondence is also present in this series.
Mullis's professional writings, including reports and articles, published and unpublished, from approximately 1939 to 1964. These represent Mullis career as a professional road engineer for the United States Bureau of Public Roads until January of 1942 when he entered the private sector as a consulting engineer for Southern Aggregates and Pratt, Lassiter and Watkins, a Raleigh, North Carolina-based engineering firm for which he worked until retiring in 1956. Sizable amounts of correspondence, especially professional responses and congratulations from friends and family, accompany two published papers: "Principles Applying to Highway Roadbeds" )February 1939) and "Properties of Roadbeds" (1963).
These notes pertain to Mullis's professional research and include charts, notes from secondary sources, copies of articles, and listings of principles relevant to the construction of roadbeds.
This series contains brochures and photos of equipment including compacting rollers and tractors used in the construction of roadbeds, earthen dams and other types of projects requiring soil compaction.
This collection is open for research; access requires at least 48 hours advance notice. Because of the nature of certain archival formats, including digital and audio-visual materials, access to digital files may require additional advanced notice.
