The process of grading a soil is in accordance with either the Unified Soil Classification System or the AASHTO Soil Classification System. The steps in grading a soil are data collection, calculating coefficients of uniformity and curvature, and grading the soil based on the grading criteria given in the used soil classification system.

Maintaining a systematic record of individual assets (an inventory)—e.g., acquisition cost, original service life, remaining useful life, physical condition, repair and maintenance consistency; Developing a defined program for sustaining the aggregate body of assets through deterioration modeling, planned maintenance, repair, and replacement ...
The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes.
A site plan or a plot plan is a type of drawing used by architects, landscape architects, urban planners, and engineers which shows existing and proposed conditions for a given area, typically a parcel of land which is to be modified. Sites plan typically show buildings, roads, sidewalks and paths/trails, parking, drainage facilities, sanitary ...
Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.
Each member state must produce a plan for each of the river basin districts within its territory. Plans must include: objectives for each water body; reasons for not achieving objectives where relevant; and the programme of actions required to meet the objectives. River Basin Management Plans were published for several member states in December ...
Drainage gradient (DG) is a term in road design, defined as the combined slope due to road surface cross slope (CS) and longitudinal slope (hilliness). Although the term may not be used, the concept is also used in roof design and landscape architecture. If the drainage gradient is too low, rain and melt water drainage will be insufficient.
Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
