Basic measure of the critical water contents of fine-grained soils, such as silt and clay, as they transition from a solid to liquid. This test is performed only in soil fraction passing through no.40 sieve (0.475mm).
AASHTO classification system
Atterberg Limits
Attenborough Limits
USCS Score
The water content at which a silt or clay material will just begin to crumble when a fine-grained soil can no longer be remolded without cracking
Liquid Limit
Slump Test
Plastic Limit
Plasticity Limit
Classifies inorganic soils for suitability as sub-grade materials in terms of good drainage & bearing capacity

Soil Boring Test
Moisture content of a fine-grained soils at which it changes from behaving like a liquid to a plastic state.

Liquid Limit
Liquidity state
Liquid index
Stoned filled wire baskets used to stabilize soil and prevent erosion.
(a)
This system of stabilizing soil and preventing erosion is particularly advantageous when constructing rock linings in areas inaccessible to trucks or large construction equipment. The wire baskets also allow steeper channel linings to be constructed
(a)
A layer of broken stones thrown together irregularly on an embankment to prevent erosion. Also known as “rock lining.”
(a)
Consists of continuous extrusion of polymeric ribs forming void space through which provide in-plane flow capacity.
Geotextile
Geomembranes
Geocomposites
Geonets
Continuous polymer sheets that are impermeable. Frequently used as ground and pond lining , or as a roofing membrane. Quite fragile and should generally not be subjected to tensile stresses.
Geotextile
Geofabric
Geomembrane
Geocomposites
Woven or non-woven fabric made from polyester or polypropylene. Generally used for reinforcement, separation, and filtration.
Geofabric
Geotextile
Geocomposite
Geomembrane
3-dimensional prefabricated polymeric systems 100-200mm high. Originally developed to repidly stabilized soft subgrades for mobilization of large equipments. Now frequently used for protection & stabilization of steep slope surfaces and channel linings.
(a)
Type of chemical used to control termites
(a)
Construction materials that use synthetic components made for use with or within earth materials. Divided into 5 different categories: Geotextile, geomembrane, geonets, geocomposites, geocells.
(a)
Type of steel mesh that is fine enough to keep even tiny termites from passing through it. It is used in slab construction, and to wrap pipes and other access areas.
(a)
If a geotextile is used to prevent the movement of fine particles from the soil through which seepage occurs. Then it is used for what?
Filtration
Reinforcement
Separation
Sediment control
A combination of geosynthetic components, usually sheet or edge drains consisting of a prefabricated core to which a geotextile is bonded
(a)
A paving type that is consisted of concrete, brick, or stone unit pavers laid out on a sand setting bed that is somehow resilient and which distributes loads to the sub-grade in a radiating manner
Turf pavement
Rigid pavement
Flexible pavement
Cobbled pavement
A type of physical barrier against termites that employs a layer of particles. Such particles must be large enough to prevent the termites from moving through it and form tunnels. This barrier is more uniform, and effective than chemical barriers and would not require reapplication.
(a)
A pavement type that employs reinforced concrete slabs or paving units mortared over a concrete slab.

Soil, crushed stone, and sand used to raise an existing grade, or as a man-made-deposit, generally used under spread footings, pavers, or concrete slabs on grade.
(a)
defined under AASHTO Soil Classification system, this is the type of particle that passes through no.10 sieve but is retained at no.40 sieve
Course sand
Fine sand
Silt-clay particles
Gravel
Soil materials suitable as fill or sub-grade, selevted laboratory approved pit-run gravel, disintegrated granite, sand, shale, cinders, or other similar materials with not more than 35% fraction passing the no.200 sieve
Granular fill
Barrow fill
Borrow fill
Base course

Fill Materials
Base Course Materials
Basic course Materials
Granular Filters
soil materials conforming to above general fill requirements and to ASTM C33, size 67, with a sand equivalent of not less than 50% used to prevent the movement of fine particles out of soils and other natural materials through seepage.
