What You'll Learn
Diesel fuel is illegal to use as an asphalt release agent
The use of diesel fuel as a release agent poses several health and safety risks. With a low flash point of around 130°F, diesel fuel can quickly vaporize into a dangerous gas, creating the risk of combustion and explosions. This poses a significant threat to the safety of workers and can also damage equipment. In addition, exposure to diesel vapors can have adverse effects on the respiratory system and has been linked to worsened asthma, allergies, bronchitis, and lung function. There is also evidence of potential increased risks of heart problems, premature death, and lung cancer.
The use of diesel fuel as an asphalt release agent also negatively impacts the quality of the pavement. Over time, diesel fuel can cut through the asphalt, causing it to disintegrate and fail prematurely. This results in a shortened lifespan of the pavement, compromising the integrity of the asphalt mix.
As a result of these issues, asphalt plants and DOT inspectors are cracking down on the use of diesel fuel, and companies are being fined for having diesel in their sprayers. It is important for contractors to switch to alternative release agents that are compliant with regulations and safer for workers and the environment, such as PavePro, which is designed to outperform diesel fuel and prevent asphalt buildup.

Diesel fuel ruins the asphalt mix
Diesel fuel is a hydrocarbon-based fuel that contains over 40 pollutants and toxic compounds that pose health risks to workers. Studies show that exposure to diesel vapours primarily affects the respiratory system and worsens asthma, allergies, bronchitis, and lung function. There is also evidence that the vapours emitted from diesel fuel can increase the risk of heart problems, premature death, and lung cancer.
Diesel fuel is a stripping agent. Its solvency breaks the bitumen down and strips it from the aggregate, very quickly. When diesel fuel gets into the asphalt, it immediately starts to break down the oils in the mix. After laying the fresh mat, the diesel doesn't go anywhere. It keeps eating through the asphalt and cutting the oil. Diesel fuel takes nearly 3 months before it biodegrades and stops affecting the pavement. By the time it has biodegraded, the diesel fuel has already wreaked havoc in the asphalt, disintegrating it and shortening the lifespan of the pavement.
The National Transportation Product Evaluation Program (NTPEP) was formed by the American Association of State Highway and Transportation Officials. NTPEP helps DOTs and contractors test products for their effectiveness and safety to ensure that projects are completed using the best products available that don't harm the quality of the work. NTPEP has an Asphalt Stripping Test that tests whether or not an asphalt release agent (ARA) strips the asphalt cement from the aggregate. Diesel fuel does not pass this test.
Asphalt plants are asking for proof of compliant release agents, and crews are getting fined for having diesel in a sprayer. Nearly every day, companies are getting fined for breaking the law by having diesel fuel in their sprayers. The Oil Pollution Act of 1990, The Clean Water Act of 1972, and The Resource Conservation and Recovery Act all forbid using diesel fuel as an asphalt release agent. These acts impose fines of hundreds of thousands of dollars if a contractor is found in violation of them.

Diesel fuel is a health hazard for workers
Diesel fuel has been the asphalt paving industry's gold standard as an asphalt release agent for decades. However, it poses several health risks to workers and is now illegal under multiple federal laws.
Diesel is a hydrocarbon-based fuel that contains a long list of over 40 pollutants and toxic compounds. The primary toxic compounds that affect the health and safety of workers include those that affect the respiratory system, worsening asthma, allergies, bronchitis, and lung function. Studies have also shown that exposure to diesel vapours can increase the risk of heart problems, premature death, lung cancer, bladder cancer, and other effects on the immune, urinary, and cardiovascular systems. For example, some studies have found links between exposure to diesel exhaust and asthma, kidney damage, and increased blood pressure.
The possible health effects of diesel fuel exposure depend on the length and frequency of exposure, the amount of exposure, and individual factors such as age, sex, genetic traits, and diet. Short-term exposure to diesel vapours can cause nausea, eye irritation, increased blood pressure, headaches, lightheadedness, loss of appetite, poor coordination, and difficulty concentrating. Skin contact with diesel fuel can also cause skin irritation.
Due to these health risks, asphalt plants are now requiring purchase receipts of diesel fuel alternatives, and inspectors are cracking down on contractors who continue to use diesel fuel. As a result, thousands of companies are switching to alternatives like PavePro, which is safer, more effective, and environmentally friendly.

Diesel fuel is environmentally damaging
Diesel fuel has been used as an asphalt release agent in the paving industry for decades. However, it has recently been banned under multiple federal laws, and using diesel as a release agent can lead to severe penalties. Diesel fuel is not only illegal but also environmentally damaging.
Diesel fuel contains a long list of over 40 pollutants and toxic compounds that pose health risks for workers. Studies show that exposure to diesel vapors primarily affects the respiratory system and worsens asthma, allergies, bronchitis, and lung function. There is also evidence that diesel vapors can increase the risk of heart problems, premature death, and lung cancer. The use of diesel fuel as a release agent is, therefore, detrimental to the health and safety of workers.
In addition to the direct health impacts on workers, diesel fuel also has indirect environmental effects. Emissions from diesel engines contribute to the production of ground-level ozone, which damages crops, trees, and other vegetation. Diesel engines also produce acid rain, which affects soil, lakes, and streams and enters the human food chain through water, produce, meat, and fish. These emissions contribute to property damage and reduced visibility.
Furthermore, diesel fuel can ruin the asphalt pavement that has been laid. Diesel fuel acts as a stripping agent, breaking down the bitumen and stripping it from the aggregate. This process disintegrates the asphalt and shortens the lifespan of the pavement, causing it to fail more quickly than it should.
As a result of the environmental and health impacts of diesel fuel, alternative products such as PavePro have been developed. PavePro is a superior, safer, and more effective asphalt release agent that is environmentally friendly and compliant with regulations. It works better than diesel at preventing buildup and biodegrades quickly, ensuring the integrity of the asphalt mix.
