nominal maximum aggregate size (NMAS) between ¾ inch (19 mm) and 1.5 inches (37.5 mm). This defi - nition focuses on specific aggregate size because the size of the aggregate relative to the asphalt lift thickness was considered as a major contributor to mixture strength, particularly at slow loading rates (Davis, 1988).
Aggregates are sand, gravel and crushed stone. Other materials like slag and recycled concrete can be considered aggregates as well. Aggregates can be put in place as washed stone, mixed with cement for pouring concrete for paving or with asphalt for paving. Commodity Description. Aggregates are a broad category of construction materials.

The particle size used in concrete mixes will vary, but typically it will comprise a mix of fine aggregate (<4.75mm size) and coarse aggregate (usually 9.5mm-37.5mm size). A coarse aggregate of 20mm size is most commonly used for reinforced concrete, with a larger 40mm size for mass concrete. Road subbase

The most significant energy centers are drying aggregate, heating stored asphalt binder and mixed asphalt, and for the electricity needed to run motors for the production process (NAPA 2023). • Fuel use for aggregate drying. The largest use of fuel in the plant is the aggregate drying burner, which is
Maximum Size . Maximum aggregate size can affect HMA and base/Subbase courses in several ways. In HMA, instability may result from excessively small maximum sizes; and poor workability and/or segregation may result from excessively large maximum sizes (Roberts et al., 1996). ASTM C 125 defines the maximum aggregate size in one of two ways:
Typically a 1/2" aggregate asphalt is used as a structural layer for a driveway and offers a good mix of a smooth finish with a strong larger aggregate structure. Alternatively 3/8" asphalt is used for filling potholes, performing small and thin maintenance surface patches as it consists of smaller aggregate and more sand material for an ...

As a rule of thumb however, the depth should be at least 4 times the dimension of the largest nominal size in the mix for surface course (i.e. 40mm depth for 10mm asphalt concrete); and at least 2.5 times the dimension of the largest aggregate size in the mix for base and binder courses (i.e. 50mm for 20mm asphalt concrete).
Asphalt • Residue from the vacuum distillation of crude oil • Crude oil contains 1-60% asphalt depending on the source • 36 million ton asphalt used in USA each year • 31 million ton used in road construction, rest mostly in roofing • 2-3 million ton used in emulsions, rest mostly in hot mix • 7-10 million ton emulsion worldwide
The two types of asphalt mixing plants: • Asphalt batch plants • Asphalt drum plants / continuous type. The asphalt batch plants can make the hot mix asphalt material in batches. This batch size gets fixed from the control panel. The plant can keep on producing the batches as long as the set production goal is achieved.
