Coarse aggregates consist of gravel, crushed stone or recycled concrete with particle sizes of ranging from 3/8-inch to 1.5 inches. Coarse aggregates are used in a wide range of construction applications, notably in concrete and asphalt mixes. Common uses for coarse crushed stone. • Concrete aggregate.

Superpave mix design specifies aggregate gradation control points through which aggregate gradations must pass. These control points are very general and are a starting point for a job mix formula.. These tables (data taken from AASHTO MP 2, Standard Specification for Superpave Volumetric Mix Design) show typical Superpave aggregate specifications for 37.5 mm (1.5 inch) down to 9.5 mm (0.375 ...
Note that the ASTM and AASHTO methods differ somewhat in the maximum size of aggregate particles that can be tested. Moreover, owing to the use of a heavier hammer and higher drop height, the modi- fied compaction procedure imparts much higher compaction energy to the aggregate specimen (4.5 times) than does the standard compaction procedure.

“Fractured aggregate is defined as an angular, rough, or broken surface of an aggregate particle created by crushing, or by other means. A face is considered a “fractured face” whenever one-half or more of the projected area, when viewed normal to that face, is fractured with sharp and well-defined edges: this excludes small nicks.
5 numbered sieve, like a No. 16, it means the number of openings per inch (in either direction), sixteen in this case. And AASHTO sizes define specific gradations for specific uses. So, after the aggregate producer crushes and screens aggregate to meet one of the AASHTO sizes, it is the responsibility of
Reading time: 5 minutes. The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. Fig 1: Aggregates used in production of concrete. The aggregates are broadly classified into ...

This process causes salt crystals to ...
Dec 01, 2014 A In the case of manufactured sand, if the material finer than the No. 200 sieve consists of the dust of fracture, essentially free of clay or shale, these limits are permitted to be increased to 5 and 7%, respectively.. The soundness of fine aggregates can be determined by subjecting the material to five cycles of the soundness test. The weighted average loss cannot be greater than 10% when ...
