What is well graded granular material?
What is well graded granular material?
A well graded soil is a soil that contains particles of a wide range of sizes and has a good representation of all sizes from the No. 4 to No. 200 sieves. A well graded gravel is classified as GW while a well graded sand is classified as SW.
What is 6N backfill?
6N. Also known as Crushed Concrete, Brick Rubble. Size: 20mm to dust. Application: This aggregate consists of crushed concrete, brick and mortar. It’s created as a by-product from demolition projects and used as a backfill material for concrete structures such as bridge abutments.
What is class 6H granular material?

What is selected granular fill?
Granular fill shall consist of pit-run gravel, sand or crushed gravel placed upon the prepared areas and in excavations, at locations and to thicknesses specified.
How do you tell if a soil is well graded?
A soil is said to well grade if it has a good representation of all grain sizes. If the soil grains are approximately of same size, then the sample is described as poorly graded. A soil is said to be gap graded if the intermediate grain sizes are absent.
What is 6F5 used for?
6F5 Recycled Crushed Concrete (75mm to dust) Uses: Capping layer for larger road and highway construction, civil engineering, driveways, landscaping, pathways and as a general fill material.
What is selected fill?
Dumped fills made up of selected materials. These fills are used when it is desired to utilize a particular property of a soil or rock and this property can be secured solely by selective excavation.
What is granular size?
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. Granular material can range from very small colloidal particles, through clay, silt, sand, gravel, and cobbles, to boulders.
What is selected fill material?
Unselected or selected filling refers to the materials used for filling an area where the materials are compacted with the aim of filling a depression. An embankment is thus just another type of fill. This type of fill contains anything from soil and aggregate to rock, crushed rock, and sand.
What are the different grades of granular material?
6C – Selected uniformly graded granular material (Starter layer) 6D – Selected uniformly graded granular material (Starter layer below pulverised fuel ash) 6E – Selected granular material, Class 9A (For stabilisation with cement to form capping)
What does 6J 6K mean in construction?
6I – Selected well graded granular material (Fill to reinforced soil and anchored earth structures) 6J – Selected uniformly graded granular material (Fill to reinforced soil and anchored earth) 6K – Selected granular material (Lower bedding for corrugated steel buried structures)
What are the different types of General fill materials?
1A – Well graded granular material (General fill) 1B – Uniformly graded granular material (General fill) 1C – Coarse granular material (General fill) 2A – Dry cohesive material (General fill) 2B – Dry cohesive material (General fill) 2C – Stoney cohesive material (General fill) 2D – Silty cohesive material (General fill)
