Utilized in the construction of roads, Asphalt is a semi-solid form of petroleum that has been blackened and rendered sticky. This unique combination contains hydrogen, sulfates, and carbon compounds as well as an unpleasant smell.
Asphalt is a commonly used material for building roads as it can help achieve a firmer surface. Heat exposure can make the smell of asphalt stronger when it radiates into the atmosphere. The odor is overpowering and the only smell detected in the air.
What Causes the Strong Asphalt Smell
The asphalt smell is caused by the presence of aromatic hydrocarbons in asphalt. These compounds, also known as volatile organic compounds (VOCs), evaporate easily and are responsible for asphalt’s strong odor. VOCs are released during asphalt production and application, especially when the asphalt is heated.
Asphalt has a melting point of around 500 degrees Fahrenheit, which is why asphalt workers must take proper safety precautions. On hot days asphalt can become gooey and even more pungent than usual.
In addition to asphalt’s volatile organic compounds, asphalt contains other smelly ingredients such as sulfur dioxide and nitrogen oxides. These compounds are released when the asphalt is heated during application or maintenance. They can cause a strong sulfur-like smell that may linger in the air for days or weeks after asphalt is applied.
The asphalt smell can be unpleasant and overwhelming, but it shouldn’t last too long. The odor tends to dissipate over time as asphalt ages and weathers. In any case, asphalt workers are required to wear proper personal protective equipment to protect themselves from the asphalt smell and any other potential hazards.
Overall, asphalt has a strong odor because of the presence of volatile organic compounds as well as sulfur dioxide and nitrogen oxides. It is important that asphalt workers take necessary safety precautions when working with asphalt due to its powerful smell. With proper care and maintenance, asphalt can last for many years and provide safe and secure roadways.
