One of the original authors of the ASTM Standard Test Method D 915, “Testing Soil-Bituminous Mixtures,” Earl Klinger significantly enhanced the development of test methods for evaluating asphalt materials and mixtures. He also did valuable work with the Asphalt Institute in developing asphalt pavement thickness design methods and procedures. At various times he served as chairman of several Institute technical committees.
A graduate of West Virginia University, Mr. Klinger spent the early years of his career with various asphalt paving contracting firms. He also served for fourteen years with the West Virginia State Roads Commission in the materials field, where he became interested in the specialized area of asphalt mix design.
In 1936, he joined the Standard Oil Company in New Jersey and worked with Standard and its affiliates until his retirement from Esso Research and Engineering in May of 1961. His career with these firms included service in both domestic and foreign operations.
Mr. Klinger was active for many years in technical organizations including the American Society of Testing and Materials, the Association of Asphalt Paving Technologists, the Highway Research Board, and the American Road Builders Association.
