If crushed carbonate quarry rock (limestone or dolostone) is used, the minus #200 [75 um] sized portion of the rock insoluble residue shall not exceed 10% by weight. Blending of sources and/or beds with an insoluble residue up to 15% is allowed to meet the 10% insoluble
· You need to have a specification. Other than the resistivity test you may consider aggregates gradation test either by the quarry or by a third party. There are always some smalls and fines, the gradation test will confirm whether the test samples meet your specification. Specify clear crushed stones not rock.
The extraction of hard rock that is turned into various crushed stone grades is a great economic indicator. Crushed stone is and will continue to be a very integral part of things we build. If you are working on a construction project and need help deciding what crushed stone grade you need, or need crushed stone in bulk for delivery, contact ...
in this specification. 4 Fractured Faces The crushed rock ballast or trowelling stone shall have at least 75% of the particles by mass with two or more fractured faces and at least 98% of the particles by mass with one fractured face. The above percentages will be required within each sieve size coarser than 3/4-inch (19 mm). 5 Flat Pieces
The counterfort is embedded into the compacted fill, immediately behind the face panel. LOCK+LOAD has tested the embedment of the counterfort with various different confining stresses. The fill in the counterfort zone is currently specified as clean crushed rock compacted to a specific performance specification.

crushed rock in small quantities to improve its workability and physical properties. Aggregates . For the purposes of this specification, fine aggregate shall be the portion of the crushed rock mixture passing the 4.75 mm sieve and coarse aggregates shall be the portion of the crushed rock mixture retained on the 4.75 mm sieve.
Specifications . Many local jurisdictions use Caltrans specifications Southern California, the Greenbook is commonly used. (See Greenbook discussion below.) Where recycled aggregate is allowed, it must also, of course, meet the same grading and quality specifications as aggregate.
the specifications for earth fill. 9.28 ROCK FILL .1 Rock fill shall include all fills comprised of material containing more than 85% by volume of rock larger than 150 mm in size, free of organic and deleterious matter. Rock fill shall not contain rocks greater than 600 mm in diameter and be approved by the Engineer prior to placement.
Washington Rock Quarries has been producing competitively priced rock, sand, and soil since 1990. Over the years, we developed a quality control program to help us make a wide variety of crushed rock and crushed stone products that meet tough customer specifications.
crushed rock, gravel, stone, sand and fines free from sod, roots and organic material. The crush count is the percentage by weight of aggregate particles retained on a 4.75mm sieve which are not shale or ironstone and which have at least one freshly fractured face.
CAA angularity as measured by fractured face percentage can range from 0 percent (e.g., smooth river rock) to 100 percent (e.g., some mechanically crushed rock). Many specifications use minimum CAA values between 80 and 100. Calculations (See Interactive Equation)
to modify the specifications to suit a local material source or project, it is best to begin with a state specification. Notice the major differences in the above specification in the top-sized material and the smallest sized material. The base course requires of the material to pass a 1 inch sieve, but allows up to 20% of the stone to be
4.2 Specifications differ as to the number of fractured faces required on a fractured particle, and they also differ as to whether percentage by mass or percentage by particle count shall be used. If the specification does not specify, use the criterion of at least one fractured face …
For over a century, Dolese Bros. Co. has provided the aggregates, concrete, and products used to build the world around us. The company''s dedication to service and quality has helped it grow from humble beginnings to a three-state 1,000-employee operation.
The crushed rock ballast shall be fully issued from crushing operations. The crushed rock ballast shall have at least 75 % of the particles by mass with two or more fractured faces and at least 98 % of the particles by mass with one fractured face. The above percentages will be required within each sieve size coarser than ¾ inch (19 mm).
Within the Specifications and Contract, reference to the English system of measurement symbols is a reference to the U.S. Customary (Inch-pound) system. Some of the symbols for units of measurement used in the Specifications and in the Bid Schedule are defined as shown in Table 101.3:1, "Measurement Symbols." The symbols for

for that class/type of aggregate in the specifications. SCOPE This test procedure determines the amount (percent) of fracture faced rock particles, by visual inspection that meets specific requirements. The fractured face of each rock particle must meet a minimum cross-sectional area. Specifications contain requirements for percentage of crushed
