Get PriceEngineering properties of fills depend upon the type of soil its water content and the degree of compaction Gravel It is a type of coarse grained soil The particle size ranges from to 80mm It is a cohesion less material
Get PriceType 2 gravel is a combination of small stones no more than in diameter and stone dust typically used in the construction industry It is not used as a decorative or landscaping material Because it contains stone dust Type 2 gravel will settle and become more compacted than gravels that do not include dust The best use for Type 2 gravel is filling in holes It can be used by road crews to fill in potholes Construction crews use Type 2 gravel
Get Price· Gravel and sand Dry compact gravel or gravel and sand subsoils are usually adequate for strip foundations Generally a depth of 700mm is acceptable as long as the ground has adequate bearing capacity If the water table is high for instance if the gravel is submerged the bearing capacity will be halved so it s important to keep the foundations as high as possible A shallow

Get PriceIf the soil is classified as a gravel it is then identified as either clean or dirty Dirty means that the gravel contains an appreciable greater than 10 % amount of material that passes a in mm opening fines and clean means that the gravel is essentially free of fines less than 10 % The use of the terms clean and dirty are for distinction purposes only and should
Get PriceIf the soil has 5 12% by weight of fines passing a #200 sieve 5% < P #200 < 12% both grain size distribution and plasticity have a significant effect on the engineering properties of the soil and dual notation may be used for the group symbol For example GW GM corresponds to well graded gravel with silt If the soil has more than 15% by weight retained on a #4 sieve R #4 > 15%
