Elected July 2005

Richard G. Ahlvin


Mr. Richard G. Ahlvin's career spans 60 years of serving the transportation engineering profession as a consultant, professor, research engineer, anf top-level manager and administrator.

In each capacity of his career, he aided the profession and the hot-mix asphalt industry with developments and achievements that have contributed to the sucess of our industry.


Mr. Ahlvin's career started in 1945, when he joined Consoer, Townsend and Associates, working as a junior civil engineer. From 1947 to 1949 he taught engineering courses at Purdue University; in 1948 he joined the Army Corps of Engineers Waterways Experiment Station (WES) and retired in 1980 as the Assistant Chief of the Soils and Pavements Divisions. Following his retirement from WES, he served as airport pavement consultant for the Federal Aviation Administration (FAA), International Civil Aviation Organization (ICAO), MinConsult of Malaysia, and others.


Mr. Ahlvin served in the Army Air Corps and Corps of Engineers during World War II in airfield construction and maintenance in Germany and France.


While in the Corps of Engineers, he made numerous contributions to pavement engineering; many of these are in use today all around the world. He was primarily responsible for development of the Corps of Engineers flexible pavement design method, commonly known as the CBR method, which continues to be used by many U.S. agencies and a number of other countries. The CBR method is the most widely used procedure for design and evaluation of airfield and highway pavements, and is commonly used as a reference for newer, more theoretical methods.


Mr. Ahlvin's consulting career has included the design and construction of flexible airfield pavements in East and Wesr Malaysia, Kuwnit, and projects within the U.S. Mr. Ahlvin was instrumental in the development of the International Civil Aviation Organization's CAN/PCN method for reporting aircraft weight-bearing limits of pavements. He provided the concept that finally led to acceptance by the international community. This method allows pavement strength to be matched with aircraft loading to quickly determine effect of passes with the aircraft in question. 


Mr. Ahlvin's efforts over the past 60 yeas have led to much improved performance of HMA pavements and has greatly enhanced the use of HMA throughout the world.
