Polycrystalline solids are an aggregate of a large number of small crystals or grains in which the structure is regular, but the crystals or grains are arranged in a random fashion. The extent to which a solid is crystalline has important effects on its physical properties.

Specification requirements were established for the properties of calcined bauxite and steel slag for HFST and friction surfacing with respect to LAA, Micro-Deval abrasion, PSV, Al2O3 content, and fine aggregate angularity (FAA). Specification requirements were also developed for HFST aggregate gradation and surface friction performance.
2018 Nation AASHTO Sweet Sixteen Award, as one of the sixteen High Value Research Projects in the nation, for the Purdue-INDOT joint research project "Friction Surface Treatment Selection: Aggregate Properties, Surface Characteristics, Alternative Treatments, and Safety Effects".
Aggregate, gravel or crushed rock material, about 0.5 to 2.5 inches in diameter, is generally used to distribute effluent. In Indiana it is mainly gravel from outwash or crushed limestone. Leaching chambers may replace aggregate in a trench. A chamber is an open-bottom, arch-shaped, plastic structure about 2 to 3 feet wide, 6 to 9 feet long ...

In contrast, physicists have developed techniques to model global properties of large complex networks. Their models describe average statistics of the network and focus less on the individual links between particular nodes.
Consensus aggregate properties, specific gravity tests, and gradation analysis were performed on three replicates each of the and recovered aggregates. Only the sand equivalent test and aggregate-specific gravities showed regular significant differences.

the mechanical properties and durability of the recycled aggregate concrete [2-11]. In general, the properties of ordinary Portland cement concrete (OPC) depend on the characteristics and quality of its components; this is true also for recycled aggregate concrete. Due to the wide variety and quality of recycled aggregate available properties
An analytical measure of the vertical uniformity of values in a given distribution calculated by dividing the mean ratio by the aggregate ratio. Appraisals are regressive (greater than 1)if high value properties are under-assessed compared to low-value properties.
