Highway and bridge construction bulk materials classification code
1 Scope
This standard specifies the classification of road and bridge construction, steel, cement, asphalt, fuel materials and other commonly used materials classification principles and methods, compiled
Code principles and methods, classification coding structure and coding table.
This standard applies to all kinds of commonly used bulk materials classification, coding and information exchange.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Line classification methodoflinearclassification
The classification of objects according to the selected number of attributes (or characteristics), successively divided into several levels, each level is divided into several categories. Same point
Branches with the same level constitute a juxtaposition between categories, between different levels constitute a subordinate category.
[GB/T 10113-2003, Definition 2.1.5]
3 classification principles and methods
3.1 classification principle
3.1.1 Co-ordinate categories Do not overlap each other's coverage and do not overlap.
3.1.2 In accordance with the material properties selected by a number of attributes successively into a number of hierarchical relationship between the categories and the formation of a gradual expansion
Classification system. Such as steel in accordance with the shape, material, size as a basis for classification, followed by layer by layer.
3.1.3 The name of the category should be selected in line with national standards or industry generally agreed material name, such as the standard name for rebar hot-rolled ribbed
Reinforced.
3.1.4 The granularity of the classification system is evenly distributed, and the materials of the same type are in a similar granularity.
3.2 classification method
The bulk materials used in the construction of highways and bridges refer to those commonly used in the construction of highways and bridges, which are purchased and used in large quantities, such as steel,
Cement, asphalt, fuel, etc., the classification of the use of line classification, mainly by raw materials materials, production technology, the existence of morphology, functional use and by
Attention and other factors to classify.
4 coding principles and methods
4.1 coding principle
4.1.1 Uniqueness
Each kind of material corresponds to only one code. Even if a material is no longer used, its code will be permanently saved as a unique code.
4.1.2 scalability
Leaving enough room for expansion, according to the actual situation of the classification category expansion.
