5×10 factory run stone mesh 8x13mm

5×10 stone (also known as screened stone or 5-10 mm stone) is a type of crushed stone with particle size from 5 mm to 10 mm, used as a large aggregate in asphalt concrete (Asphalt Concrete – AC).

This type of stone is often crushed from natural stone such asgranite, basalt, or limestone, has high durability and good load-bearing capacity when mixed with asphalt.

Characteristics of 5×10 stone

• Grain size: 5 mm – 10 mm.
• Shape: Angular, helps increase adhesion to asphalt.
• Fine grain content: Low, ensuring suitable porosity.
• High hardness, good load-bearing capacity, less wear when subjected to heavy loads.
• Color: Gray, black (depending on the type of original stone: granite, basalt, lime).

1. Main ingredients in asphalt concrete mixture

• 5×10 stone is a large aggregate, which helps increase the durability and load-bearing capacity of asphalt concrete.
• Used in fine-grain asphalt concrete and medium-grain asphalt concrete.

2. Road construction

• Used as a load-bearing asphalt pavement layer.
• Application in highways, national highways, inner-city roads, airports, ports…

3. Stabilize the road surface structure

• Helps increase the load-bearing capacity and anti-sagging of the road surface.
• Supports against cracking and rutting wheel tracks.

1. Standard grain composition (TCVN 8819:2011)

2. Important physical and mechanical indicators

• TCVN 8819:2011 – Requirements for hot mix asphalt concrete.
• TCVN 7570:2006 – Standard for coarse aggregate in concrete.
• ASTM D692/D692M – American standard for asphalt concrete aggregate.

1. Advantages

• Increases adhesion to asphalt – Thanks to the angular shape.
• Increases the density of asphalt concrete – Reduces voids, increases water resistance.
• Prevents road surface cracking – Helps reduce wheel rutting.
• High durability – Less wear under heavy loads.

2. Disadvantages

• Not suitable for heavy-duty asphalt concrete layers, mainly used for fine-grained asphalt concrete.
• Requires strict quality control, ensuring appropriate grain composition.
• Easily washed away during drainage, if not combined with larger aggregates.

1. Selection criteria

• Uniform size, limiting particles that are too small or too large.
• High hardness, limiting breakage when bearing load.
• High cleanliness, does not contain mud, clay, or fine dust.

2. Storage and transportation

• Do not mix with other types of stone, avoiding affecting the grading.
• Store in a dry place, avoiding contamination from soil and sand.
• Transport properly, limiting breakage of stone particles.

5×10 stone is an important stone in asphalt concrete structure, helping to increase asphalt adhesion, reduce voids and prevent road surface cracking.

• Main application: Fine-grained asphalt concrete layer, road surface coating, inner-city roads, parking lots.
• Applicable standards: TCVN 8819:2011, ASTM D692/D692M.
• Notes when using: Ensure the grain composition meets the standards, check the cleanliness before construction.
