proposed that deteriorated existing concrete pavement that is overlaid with asphalt has a structural coefficient of approximately 0.50. This value has since been often cited in some older design manuals. In reality, this is a conservative value, which can be used to estimate comparable pavement sections. The following table lists layer ...
Sand Equivalent Test Sets are used to indicate the relative proportions of clay-like fines in granular soils and fine aggregates. Gilson sets include everything required in ASTM and AASHTO test methods to conduct the test except the shaker.

Sand Equivalent Value of Soils and Fine Aggregate Categories of Soils based on Particle Size: o Coarse aggregate. o Fine aggregate. o Silt. ( sieve #200, size 0.075) o Clay. Clay like material are small particles in the size of clay particles that are deleterious to asphalt concrete and cause many problems such as: o Rutting.
Sand Equivalent Value Test Astm d2419 To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures. Immediately read and record the level of the top of the clay suspension and the total suspension time.
Fifteen samples of concrete sand from various loca tions in Texas were obtained. Each of these samples was thoroughly mixed and split with a sample splitter to obtain test specimens for three Loss by Decantation ·tests and three Sand Equivalent tests. The Loss by Decantation and Sand Equivalent values for samples 1
tivity and amount are reflected in the sand equivalent value hut not in the loss by decantation. Clay contami nants in concrete aggregate affect concrete properties primarily through their effect on water demand. Con crete strength and shrinkage correlate to a high degree with sand equivalent value and to a slightly lesser degree

Maximum range of absorption capacity of fine aggregate (sand) Can the absorption capacity of a fine aggregate (sand) be as large as 8%? If so, is such sand suitable for concrete casting.
Some sources quote a much higher R-value for sand and gravel aggregate but you need to look at the thickness or amount of sand or gravel when you see such quots. For example some cite sand and gravel aggregate as providing R 1.11 FOR 8 INCHES of thickness. That's equivalent to an R-value of R 0.1388 per inch, but without considering moisture level.
May 03, 2011· A lower SE value means that there is more clay and silty material than sand. So that you have a frame of reference, the Caltrans concrete sand specification requires a minimum SE value of 71 which means that 71% of the material is made up of sand and …
The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not.
5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.
Insulation R values of various materials: This article provides a Table of Insulation Values and Properties for Various Insulation Materials useful in procedures to measure or calculate heat loss in a building, defines thermal terms like BTU and calorie, provides measures of heat transmission in materials, building insulation design data, and heat loss in a building.
Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate. View Abstract ... sieve.

Apr 30, 2011· So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.

Jun 30, 2009· Either clay content should be calculated as 100-sand equivalent value to set minimum requirement as above or if we use sand equivalent, what the Spe'c should set is a maximum requirement. I read AASHTO and found that it has similar requirement to our specification.
sand reading 2clay reading • If the calculated sand equivalent is not a whole number, report it as the next higher whole number. • Higher sand equivalent values indicate “cleaner” (less fine dust or clay-like materials) aggregate. • Typical sand equivalent values range from less than 30% to more than 90%.
