Source: ASTM Standard C33/C33M The second column in the table shows the aggregate size range that is always decided prior to use. For example, if we are to prepare a concrete mix using an aggregate sample that contains a maximum particle size of 63mm and a minimum particle size of 37.5mm, we'll look through the second row and the values present in …
Our Gradation Charts show gradations of various stone, sand, and gravel products based on required specifications.
Large-particle-size graded crushed stone mixtures (LPS-GCSMs) can improve the shortcomings of conventional graded crushed stone, such as low strength, high deformation, and a low modulus of resilience. At present, there is no systematic research on the gradation design and field evaluation of the LPS-GCSMs. In this study, compaction and California bearing ratio …
Crushed Stone Grade 1-10. Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2 ...
In addition, the graded crushed stone layer plays a significant role in restraining the reflection cracking of asphalt surface course caused by shrinkage cracks in semirigid base . Thus, the durability of the combined base asphalt pavement would be effectively improved due to the strong drainage ability and the decrease of reflection cracks in ...

Conventional binding materials, such as silicate cement and lime, present high energy consumption, pollution, and carbon emissions. Therefore, we utilize crushed stone as a stabilization material.
In PCC, gradation helps determine durability, porosity, workability, cement and water requirements, strength, and shrinkage. Because of this, gradation is a primary concern in HMA and PCC mix design and thus most agencies specify …
Crushed stone #5 has gravel that is up to an inch in size. It doesn't compact well is ideal for driveway and road base. Crushed stones #8: ⅜″-½″ Crushed stones #8 are ⅜ to ½ an inch wide and are at times known as ⅜-inch washed stone or clean crushed stone because most undergo thorough cleaning to get rid of any residue or dust.
The results of the tests indicate that crushed granite with a gradation inside the ASTM specification band included in the new ASTM Specification D 2940 71T, Graded Aggregate …
The gradation curve evaluated by an equivalent passing with a grain size correction factor match the sieve analysis for crushed stone, sand and sand-crushed stone samples. The image analysis results also indicate that the crushed stone particles are more angular than sand particles, which is important in numerical analysis to simulate fresh and ...

Coarse aggregate includes all aggregate particles greater than or retained on the ½-inch sieve. ... materials consisting of sand, gravel, crushed stone, iron blast furnace slag, reverberatory furnace slag or a blend of aggregates in accordance with Table 902-3 and this ...
Crushed gravel - oversized particles are crushed and fed back into the mixture (Generally Class 1 or 2). Dense-graded - all particle sizes are present, limited voids content (Generally Class 2). Open-graded - screened material with a narrow range of particle sizes and a large voids content (Generally Class 1 or 2 depending on screen size).

Crushed Stones #5: Approx ½" to 1½ ″ Wide. Crushed stone number 5 contains gravel that is usually from around ½ inch up to 1½ inches in size. This size is mainly used for the following: As a road and slab base; Paved driveway base layer of gravel; Crushed stone patios; Drainage projects; Crushed Stones #8: Approx ⅜"- ½″ Wide
If Crushed Carbonate Stone (CCS) is used, the material must meet the gradation and physical requirements in 703.17. In rare cases these materials become soft after a rain event or over the winter. Crushed Gravel Used for 304. If crushed gravel is selected for use as aggregate base, it must be manufactured from material retained on the 1/2-inch ...
The purpose of gradation in this capacity is to enable compatibility of the aggregate with product control requirements, designs, and verification specifications. Gradation via sieve analysis works particularly well for …
In geotechnical engineering such as railway track bed and crushed stone roadbed, crushed stones with higher hardness grades are usually used as fillers. In this paper, quartz stone and limestone are used as test materials for tests. The gradation of crushed stone is shown in Fig. 1 and the specific proportion of crushed stone is shown in Table 1.
3/4 Crushed Stone. 3/4 inch crushed stone is a useful aggregate in several applications of hardscaping and has become increasingly relied upon in permeable and open graded base installations where the water that enters the system is meant to freely drain through the base material and penetrate into the subsoil or be collected into a drainage system and exfiltrated …
Gradation: Gradation is the distribution of different sized stones comprising an aggregate by percent of weight. Gradation is determined by filtering an aggregate through successively …
The gradation of crushed stones used in railway tracks plays a crucial role in determining the overall performance of the track. Proper gradation ensures that the stones are well-distributed and interlocked, providing stability and preventing track misalignment. It also affects the track's ability to manage drainage and water flow, as well as ...
