The Superpave mix design method was designed to replace the Hveem and Marshall methods. The volumetric analysis common to the Hveem and Marshall methods provides the basis for the Superpave mix design method. The Superpave system ties asphalt binder and aggregate selection into the mix design process, and considers traffic and …
The most widely used drive for rotary shakers is the triple eccentric Gyrotory drive. Using three rotating shafts, this stabilizing mechanism transmits a smooth, uniform motion to all flasks, even with unbalanced or changing loads. Each individual shaft is accurately machined, critically located and installed in a precision-bored housing.
The gyratory crusher. The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a …
The New Brunswick Scientific C-Line Series Benchtop Gyrotory Platform Shaker are Ruggedly-built for use on the bench or in an incubator or warm room, these shakers are available in two sizes and three models.
The homogeneity indices of the top and bottom horizontal cross sections of the gyratory-compacted specimens were higher than those of the Marshall specimens, which could be attributed to the rotational movement of the gyratory compactor and the boundary condition imposed by the gyratory mould. The gyratory mould was taller than the …
Gyratory seizures (GS) are a rare occurrence, but have been reported in focal seizures of frontal and temporal origins, as well as generalized epilepsies. 1, 2, 3 GS are characterized by rotation around the body axis in a circular or spiral manner, typically by at least 180 degrees or 360 degrees. 2 The term gyratory has also been used to refer …

Gyratory cone crushers are essential machines in the mining and construction industries, used to crush hard and abrasive materials into smaller pieces. In this article, we will provide a detailed guide to gyratory cone crushers, including their working principles, advantages and disadvantages, types, and applications.
Pine's GB1 Brovold Superpave Gyratory Compactor compacts 150-mm specimens and, at 304 lbs., lends itself to mobile labs and on-site testing.
A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:
The aggregate requirements are based on traffic levels, independent of gyratory compaction levels. The Superpave mix design system evaluates the volumetric properties of the compacted samples. These properties include air voids (Va), voids in mineral aggregate (VMA) and voids filled with asphalt binder (VFA), and dust to binder ratio.
