	Huber(2)
		Gyratory compaction has been used in asphalt mixture design since the 1930's when a procedure was developed by the Texas Highway Department (Department of Transportation today).The original gyrator compaction procedure was done manually.
		Studies included the shape of the gyratory densification curves and the effects of aggregate gradation, mineral filler content, and asphalt properties on the position and slope of the curve.
		The decision was made to develop a gyratory protocol which would simulate the density achieved at the end of life, a concept similar to the approach used in Marshall compaction.

	Internal combustion engine with gyratory piston and cylinder movement - Patent 3974803
		The piston and cylinder-piston elements follow opposite gyratory paths during operation of the engine to effect a variable volume combustion chamber which follows an oscillating up and down path, whereby balancing of the engine, minimal vibration operation, necessary sealing of the combustion chamber, proper cooling, and improved efficiency of operation are attained.
		Yet still another important object is an improved internal combustion rotary engine wherein gyratory movements of piston and cylinder-piston elements in an engine housing or casing compress air so that means may be provided to deliver said compressed air for charging or supercharging operation of the combustion chamber.
		An illustrative gyratory turn is seen as commencing with the offset portions being laterally and interiorly displaced in FIG.

	Development of the Superpave Gyratory Compactor
		Gyratory compaction has been used in asphalt mixture design since the 1930's when a procedure was developed y the Texas Highway Department (Department of Transportation today).The original gyrator compaction procedure was done manually.
		During the 1960's and early 1970's development o f the French gyratory compaction protocol occurred..
		The angle was required to be constant during compaction.

		This new stability parameter is based on energy measurements from the Superpave gyratory during the mix compaction.
		Gyratory stability successfully reflected the effect of binder content, aggregate gradation, aggregate types, and quality.
		Secondly, the mixes used throughout the development of the Gyratory Stability were obtained from the Asphalt Institute (AI), and consequently AI provided the performance testing results.

	The History of Gyratory Compaction
		History is a dynamic tapestry of facts and perceptions, dates and personalities. This work attempts to capture the events and rational of those who contributed significantly to the use of gyratory compaction in the design and field management of hot-mix asphalt (HMA) and discusses the challenges ahead.
		The development of the gyratory concept is attributed to Philippi, Raines, and Love of the Texas Highway Department.
		The first Texas gyratory “press” was a manual unit used on an experimental basis from 1939 to 1946, (Figure 1). In 1946, the Texas Highway Department standardized its use in specifications and test methods.

	Do they all agree?
		It is important that these devices provide consistent results from one to another, because results from contractors' mix designs are used to provide construction control and are subject to agency verification.
		When first implemented, the requirement for the gyratory compaction procedure specified that an angle of 1.25° be maintained, and this was relative to the outside of the sample mold.
		It has come to light that different brands of gyratory compactors may yield different compaction results in spite of having the required external gyratory angle.

	BBC - h2g2 - The Hanger Lane Gyratory System
		Situated on the West side of London, UK, where the North Circular Road (or A406) meets up with the Western Avenue (or the A40 if you prefer), the Hanger Lane Gyratory System is perhaps as bitter a disappointment as anyone could hope for.
		If you are unfamiliar with gyratory systems, the name seems dark and intriguing, bristling with a thousand possibilities - it just oozes Heath Robinson with a hint of Hieronymous Bosch.
		To keep in the spirit of the whole affair there even appears to be road access to it from the gyratory, presumably for the benefit of adrenaline addicts who have long since tired of relatively sane pursuits such as bungy jumping.

		Some situations may arise where only gyratory mixtures are being produced and Marshall mixtures are not a reasonable option or vice-versa.
		If gyratory design is utilized, Traffic Level 2 or 3 would be the appropriate choice.

	Route 79: Hanger Lane Gyratory
		The Hanger Lane Gyratory is the dubious-sounding name given to a big roundabout (traffic circle) in North West London.
		Everyone except, that is, the unfortunate motorist who probably used the A-Z to plot a route from A to B without appreciating that the Hanger Lane Gyratory is probably THE MOST hostile roundabout in the country.
		The Hanger Lane Gyratory - drive with extreme sense of purpose - or else you’re toast.
