Asphalt Temperature Calculator

Formula

The formula to estimate the asphalt temperature (AT) is:

\[ AT = AT_{air} + (C \times WS) \]

Where:

\( AT \) is the estimated asphalt temperature (°F).
\( AT_{air} \) is the air temperature (°F).
\( WS \) is the wind speed (mph).
\( C \) is a constant representing the effect of wind speed on asphalt temperature.

What is Asphalt Temperature?

Asphalt temperature is the temperature of the asphalt surface, which can differ from the air temperature due to factors like solar radiation, wind speed, and material properties. Accurate measurement or estimation of asphalt temperature is crucial for paving operations, as it affects the curing time, compaction, and overall quality of the asphalt pavement.

Example

For example, if the air temperature (AT_air) is 85°F, the wind speed (WS) is 10 mph, and the constant (C) is 0.5, the asphalt temperature (AT) can be calculated as follows:

\[ AT = 85 + (0.5 \times 10) = 85 + 5 = 90 \text{ °F} \]

So, the estimated asphalt temperature for these values is 90°F.
