10×16 stone is a type of crushed stone with a size of 10 mm to 16 mm, used as a large aggregate in asphalt concrete (Asphalt Concrete – AC).

This type of stone is often crushed from natural stones such as granite, basalt, or limestone, has high durability and ensures good bearing capacity when mixed with asphalt.

Characteristics of 10×16 stone

Grain size: 10 mm – 16 mm.
Shape: Angular, helps increase adhesion to asphalt.
Fine grain content: Low, ensuring suitable porosity.
High hardness, good bearing capacity, less wear when bearing heavy loads.
Color: Gray, black (depending on the type of original stone: granite, basalt, lime).

1. Main ingredients in asphalt concrete mixture

10×16 stone is a large aggregate, which helps increase the durability and load-bearing capacity of asphalt concrete.
Used in medium-grain and fine-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-sink of the road surface.
Supports against cracking and rutting of wheel tracks.

1. Standard grain composition (TCVN 8819:2011)

Sieve size (mm)	Screen passing rate (%)
16.0	100
12.5	80 – 100
10.0	50 – 85
4.75	10 – 35
2.36	0 – 10

2. Important physical and mechanical indicators

Indicators	Standard values
Compressive strength	≥ 80 MPa (depending on type stone)
Los Angeles (LA) wear and tear	≤ 35%
Impact (AI)	≤ 30%
Content of dust, silt, clay	≤ 1%
Water absorption	≤ 2%
Proportion of flat and diamond seeds	≤ 15%

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

Good load-bearing capacity – High strength, suitable for highways and airports.
Increased adhesion to asphalt – Thanks to the angular shape.
Anti-cracking of the road surface – Helps reduce rutting of wheel tracks.
High durability – Less wear under heavy loads.

2. Disadvantages

More difficult to construct than small stones, requiring specialized asphalt spreading equipment.
Higher cost than smaller stones (9.5 mm, 12.5 mm).
Requires strict quality control, ensuring suitable particle composition.

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.

10×16 stone is an important type of stone in asphalt concrete structure, helping to increase bearing capacity, prevent subsidence and cracking and prolong the life of the road surface.

Main application: Highway, airport, port, bridge and road surface.
Applicable standards: TCVN 8819:2011, ASTM D692/D692M.
Notes when using: Ensure the particle composition meets the standards, check the cleanliness before construction.
