cobbles, gravel, sand, silt, and clay. Numerous grade scales have been developed to establish the limits of size for each of these classifications. Table 3–1 shows some of the commonly used grade scales for compari-son. Note that the range in size for a particular class of particle may differ from one classification system to another.

When it comes to construction, there are many materials most people don't understand, and they assume only the experts know anything about it. This is especially true when it comes to one of the basic building materials in ready mix concrete, asphalt, masonry, and hardscaping: types of stone. We all know a stone when we see one, and we know they are …

However, silt is still heavily reliant on water content. [See Figure 4] Granular soils Granular soils range in particle size from .003" to .08" (sand) and .08" to 1.0" (fine to medium gravel). Granular soils are known for their water-draining properties. Characteristics Sand and gravel obtain maximum density in either a fully dry or saturated ...

The Aggregate crushed value(ACV), determined in accordance with TMH1 method B1, shall not exceed the appropriate value in the 3602/3.

inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the mixture by weight and 75 to 85 percent by volume.

or crushing strength, is a measure of the plasticity of the soil. Crushing of dry clay lumps is relatively difficult, whereas silt lumps break quite easily. Test the strength of the dry pats or lumps by crushing between the fingers and note …

8.3 Percent silt: % silt = corrected hydrometer reading at 40 sec. x 100/ wt. of sample - % clay 8.4 Percent sand: % sand = 100% - % silt - % clay 9. Quality Control 9.1 Standard soil - a standard soil of known particle size content is analyzed with each batch of samples to check for instrument calibration and procedural accuracy. 10. Reporting

then the gravel will be classified as a clayey gravel (GC). Once the determination has been made whether the fines are silt or clay, the classification can be further refined by estimating the percentage of sand size particles present in the sample. If the soil is classified as a sand, the same criteria that were applied to gravels are

Percentage of Silt Content = (V1/V2) x 100. V1 - Volume of silt layer. V2 - Volume of sand layer. For example, for a given sand sample, if V1 comes out to be 9 and V2 is 130, the % silt content would be 6.9 %. The permissible value of silt content in Sand is 8%, hence the sand sample is ok and can be used for construction purposes.

Fine aggregates should not contain more than 5% of silt, clay lumps, and chemical impurities. The silt content should not be more than 3% for river sand and 15% for manufactured sand. These materials adversely affect the hardening, strength, and durability of concrete by initialising corrosion of reinforcement.

The silt fraction is determined by measuring the proportion of loose dry surface dust that passes a 200-mesh screen, using the ASTM-C-136 method. Table 13.2.2-1 summarizes measured silt values for industrial and rural unpaved roads. Since the silt content of a rural dirt road will vary with location, it should be measured for use
