	AASHO Road Test - Wikipedia, the free encyclopedia
		The AASHO Road Test was a series of experiments carried out by the American Association of State Highway and Transportation Officials to determine how traffic contributed to the deterioration of highway pavements.
		The results from the AASHO road test were used to develop a pavement design guide, first issued in 1961 as the "AASHO Interim Guide for the Design of Rigid and Flexible Pavements", with major updates issued in 1972 and 1993.
		Unsurprisingly, the heavier vehicles reduced the servicability in a much shorter time than light vehicles, and the oft-quoted figure that damage caused by vehicles is 'related to the 4th power of their axle weight' is derived from this.

	United States Numbered Highways - Wikipedia, the free encyclopedia
		AASHO recommended that the Secretary of Agriculture work with the states to designate these routes.
		In 1934, AASHO attempted to eliminate many of the split routes by removing them from the log, and designating one of each pair as a three-digit or alternate route, or U.S. Route 37 in one case.
		In 1952 AASHO re-recognized the splits in U.S. Route 11, U.S. Route 19, U.S. Route 25, U.S. Route 31, U.S. Route 45, U.S. Route 49, U.S. Route 73 and U.S. Route 99.

	For The Common Good: The 85th Anniversary of a Historic Partnership
		With the founding of AASHO and the addition of MacDonald to the executive committee, all the pieces were in place to create the historic partnership that would be known as the federal-aid highway program.
		The draft was sent to Congress, but AASHO members from Midwestern states, many of which had less developed networks, objected to the plan and to the fact that they had not been consulted before it was submitted to Congress.
		To settle the dispute, a meeting of AASHO's executive committee was arranged to coincide with the Pan-American Road Congress at the Municipal Auditorium in Oakland, Calif., on Sept. 13-17, 1915.

	THe AASHO Road Test
		The information obtained from the AASHO Road Test was crucial in advancing knowledge of pavement structural design, pavement performance, load equivalencies, climate effects, and much more.
		The AASHO Road Test site (which eventually became part of I-80) at Ottawa, Illinois, was typical of northern climates (see Table 1).
		Each flexible pavement section in the main experiment was 30 m (100 ft.) long with all sections being separated by a transition pavement of at least 5 m (15 ft.) Table 5 summarizes the thicknesses for each loop.

	U.S. 29 Maryland to Florida
		Over the next year, AASHO acted on requests, many initiated by named trail associations, for changes in routings and numbers.
		The northern terminus, in Culpeper, was at the junction with U.S. In 1933, the District of Columbia and Maryland approached Virginia and AASHO about an extension of U.S. 29 north.
		During AASHO's annual meeting, October 9-11, 1933, in Milwaukee, Wisconsin, the Executive Committee agreed to investigate consolidation of U.S. numbered routes, the discontinuance of alternate routes and the disapproval of requests for recognition of named routes.

		AASHO and ARBA reached an agreement to assume responsibility for the workshop, and the 1964 session was held in New Orleans, La.
		At that session ARBA tried to answer the complaint that the leadership of AASHO was not sufficiently involved by putting the workshop under the wing of the AASHO-ARBA Joint Committee (later the AASHTO-AGC-ARTBA Joint Committee).
		During the 1972 Miami meeting of AASHO Administrative Subcommittee on Public Information, agreement was reached to establish a nine-member steering committee to develop objectives for the larger group and to assist in other ways in strengthening public information activities for the highway program.

		The AASHO Road Test, performed in the late 1950s, is the basis for most pavement design procedures which utilize the American Association of State Highway and Transportation Officials (AASHTO) method of equivalency factors.
		The relationships between traffic loading and pavement performance obtained from the AASHO Road Test are recognized to apply only to the conditions under which they were developed.
		The relative damage to pavements caused by new vehicle characteristics and configurations may be very different from that caused by the axle loads used at the AASHO Road Test.

	Pavement Digest
		The latter was the most extensive research on pavements ever conducted, with $26 million raised to build a test road in Ottawa, Illinois, that could be traveled around the clock for two years on six different test loops.
		(By that time, AASHO had changed its name to AASHTO, the American Association of State Highway and Transportation Officials.) The concept of equivalent single axle loads introduced by engineers at the road test was included to simplify the handling of axle loads of mixed magnitudes.
		It retains the basic algorithms developed from the AASHO Road Test as used in the previous work but was expanded to include many new considerations, such as reliability concepts, improved material characterization, drainage and environmental conditions, tied concrete shoulders or widened lanes, life-cycle cost analysis, and pavement management considerations.

		In this experiment, the materials composing the asphaltic concrete surfacing, the crushed stone base course, and the sandy gravel subbase were uniform throughout, as was also the embankment soil on which the pavement was laid.
		The serviceability concept as used at the AASHO Road Test because of its definition incorporates both cracking and accumulated permanent deformation: therefore, it was correlated with the vertical stress on the subgrade which was considered to be a measure of the general stress level in the pavement system.
		It appears that the AASHO Test Road subgrade is perhaps a particularly resilient soil at high degrees of saturation and that the conditions and method of construction may have led to somewhat higher resilience characteristics throughout the project then would result from more conventional construction procedures.

		An exactly even split between the member states of the Association of State Highway Officials (AASHO) on the continuation of the Federal-State cooperative road building plan and the death of Bureau of Public Roads (BPR) leader, Logan Waller Page in late 1918, added to the quarrel.
		The answer developed by MacDonald, in close cooperation with AASHO, was contained in the Federal Highway Act of 1921.
		Of the Act and the Bureau of Public Roads, MacDonald said in 1922, “…The Bureau does not seek to direct the states, but to cooperate with them.

	American Society of Highway Engineers
		In the 40 years since the empirical based pavement design procedures of AASHO Road Test were developed, very little change has come about on how we design pavement structures.
		Furthermore, the AASHO Road Test was based on one environmental region, geological formation and one specific vehicle type to formulate a system of pavement design for use nationally.
		Traffic volumes and truck axle weights are so dramatically different today that it becomes quite questionable to many if the designs seen today on major interstates and expressways are realistic.

		The Historic Highway began as an entity in November of 1926 when the American Association of State Highway Officials (AASHO) adopted the U.S. numbering system for marking the Nation's main Interstate highways.
		Over the years it was extended in stages to transcontinental length as improved roadways moved westward.
		It was in 1937 that AASHO approved the extension of U.S. Route 6 to Long Beach, California (a distance of 3,652 miles from Provincetown) making it the longest U.S. Route in the country.

		District officials originally proposed an I-63 designation for the Anacostia Freeway, but the American Association of State Highway Officials (AASHO) denied this request.
		AASHO proposed an I-195 designation for the route, but because it was to connect the Capital Beltway with a proposed "Inner Loop," District Officials proposed an I-295 designation.

		Idaho loadometer data and traffic classification data were reviewed and used in this study to make a comparison with the design recommendations of the AASHO Committee on Design.
		In making this comparison, it was necessary to use the AASHO recommendations for the correlation between Soil Support Value as used in their design brochure and the Resistance value as reported by California.
