Bearing Capacity of 95% compacted fill - Soil testing ...

For a well graded crushed sand and gravel (road base) Ive seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). Weve compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg. Could use that to estimate bearing capacity.

FAQ: Tips and Techniques for using Crusher fines surfacing ...

Overall trail grade averages of less than 6% will provide the most user-friendly experience and offer the most sustainable natural trail surface if compacted crusher fines are to be used. Be sure your material is crushed rock, not volcanic cinders, "red breeze," decomposed granite, pea gravel, or river rock.

Effect of Fine Content on the Bearing Capacity of Replaced ...

It was found that a fine content of 10% gives the highest dry density, if the soil is compacted according to modified proctor specifications and with the addition of fines, the footing settlement increases and the ultimate bearing carrying capacity decreases.

Allowable Load-Bearing Values of Soils and Rock | UpCodes

1804.2.2.1 Allowable Bearing Pressure of Controlled Fills Provided the capacity of the underlying soil is not exceeded, the allowable bearing pressure of controlled fill shall be limited to: 6 tons per square foot (766 kPa) for gravel and crushed rock. 3 tons per square foot (383 kPa) for recycled concrete aggregate and well-graded sand.


Sep 22, 2015 · Values of Safe Bearing Capacity The safe bearing capacity of soil should be determined on the basis of soil test data or by performing some field test such as Standard penetration test or Plate load test etc. However, in the absence of soil test data, the values of safe bearing capacity (S.B.C) as given in […]

Soil Compaction Handbook - Multiquip Inc

Soil Compaction Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs …

What are Bearing Capacity Values of Different Types of Soil?

Nov 17, 2017 · Bearing capacity of soil is the maximum load per unit area. This is the ultimate bearing capacity of soil shown in table. Dividing the ultimate soil bearing capacity by a safety factor we get the maximum safe bearing capacity of soil for design of foundations.

CIP 17 - Flowable Fill Materials

compressive cylinder strength, is greater than the bearing capacity of most compacted soil. Another method of testing for adequate hardening after placement is the ball drop test, ASTM D 6024. A diameter of indentation of less than 3 in. (75 mm) is considered adequate for most load applications.

Intro to Foundations Fill Backfilling R - CED Engineering

of bearing capacity and settlement calculations. The settlement and bearing capacity of underlying foundation soils also should be evaluated. Practically all types of construction can be founded on compacted fills, provided the structure is designed to tolerate anticipated settlements and the fill is properly placed and compacted. Good and

Recycled Base Aggregates in Pavement Applications

The bearing capacity decreases with increasing RAP content. The California Bearing Ratio (CBR) is reduced below that expected for conventional granular base when the amount of RAP exceeds 20 to 25 percent. Compacted Density: Due to the coating of asphalt cement on RAP aggregate, which inhibits compaction, the compacted density of blended

Bearing Capacity - an overview | ScienceDirect Topics

The bearing capacity in this situation relates to the number of wheel passes for a layer-separator-soft soil system and depends on the thickness and inner friction of the granular layer and the deformability and inner friction of the underlying soft soil. The granular layer should be a well-graded granular material and should be strongly compacted, to obtain high friction between the grains ...

California Bearing Ratio - Pavement Interactive

The California Bearing Ratio (CBR) test is a simple strength test that compares the bearing capacity of a material with that of a well-graded crushed stone (thus, a high quality crushed stone material should have a CBR @ 100%).It is primarily intended for, but not limited to, evaluating the strength of cohesive materials having maximum particle sizes less than 19 mm (0.75 in.) (AASHTO, 2000 [1]).

Improvement of Bearing Capacity in Recycled Aggregates ...

The California Bearing Ratio (CBR) is defined as the ratio of the force required to penetrate a circular piston of 1935 mm 2 cross section into soil in the CBR mold at a rate of about 1 mm/min, to that required for similar penetration into a standard sample of compacted crushed rock—13.24 kN and 19.96 kN at penetrations of 2.50 mm and 5.00 mm, respectively. This ratio is determined at these two penetrations …
