To return aggregate values, set the fetch element aggregate attribute to true. Then, within the entity element, set one or more attribute elements with the name, aggregate, and alias attributes. Use the aggregate attribute to specify the type of aggregation you want. The following example shows a simple aggregate query in …

For proper placement and compaction, the asphalt lift thickness should be at least 2.5 to 3.0 times the maximum particle diameter. HL 3 aggregates have a nominal maximum size of 13.2 mm, requiring a minimum mat thickness of at least 35 mm. HL 4 is a slightly coarser mix with aggregates of a nominal maximum size of 16 mm, and hence requiring a ...

Marshall stability and flow test values, density, and air voids in the mix and the mineral aggregate are all used to evaluate trial mixtures of lab-mixed, lab-compacted (LMLC) asphalt mixtures. Marshall stability and flow tests can also monitor the production of the asphalt mixture using plant mix and laboratory-compacted (PMLC) samples.

The manufacturing process is a production process that involves using raw material, equipment, labor, and other essentials to generate the final good. Technically, it is a process by which raw materials are transformed into finished goods. The process involves design, engineering, sourcing, production, and distribution.

Data flows from the whole classifier, or aggregate, to the part. A part classifier can belong to more than one aggregate classifier and it can exist independently of the aggregate. For example, a Department class can have an aggregation relationship with a Company class, which indicates that the department is part of the company.

Soil is a natural resource and a living ecosystem (the "living skin of the earth"). Soils sustain all life on earth and filter and break down natural and man-made toxins. Soils provide water, nutrients, and support, along with oxygen for the plant's root growth. Soils have four main components: mineral particles (sand, silt, and clay), organic ...

Each of the four constituents has a specific function. The coarser aggregate acts as a filler. The fine aggregate fills up the voids between the paste and the coarse aggregate. The cement in conjunction with water acts as a binder. The mobility of the mixture is aided by the cement paste, fines and nowadays, increasingly by the use of admixtures.
