Diesel fuel has been the paving industry's go-to asphalt release agent for years, but it has several drawbacks that are pushing companies to find alternatives. When diesel fuel is spilled on asphalt, it acts as a solvent, softening and dissolving the bitumen that binds the asphalt together. This causes the pavement to crumble and crack, shortening its lifespan. The damage caused by diesel fuel is permanent and can result in potholes. Aside from the environmental concerns, diesel fuel also poses legal risks, with several acts forbidding contractors from using it as a release agent.

Diesel fuel acts as a solvent, breaking down the bitumen in blacktop
Diesel fuel is a stripping agent that acts as a solvent against the tar that bonds blacktop together. It breaks down the bitumen within the blacktop, separating it from the aggregate and causing crumbling and cracking. This destruction of the blacktop's integrity shortens the overall lifespan of the pavement.
Asphalt is made of bitumen, which is produced by fractional distillation when crude oil is split into naphtha, petrol, diesel, and other products. As diesel and bitumen are both crude oil derivatives, they are essentially the same thing—hydrocarbon chains. The main difference is that the hydrocarbon chains in bitumen are much longer than those in diesel. Therefore, when diesel is spilled on blacktop, the bitumen dissolves into the diesel.
When diesel fuel gets into blacktop, it immediately starts to break down the oils in the mix. It continues to eat through the blacktop and cut the oil for up to three months before it biodegrades and stops affecting the pavement. By then, the diesel fuel has already wreaked havoc, disintegrating the blacktop and shortening its lifespan.
The use of diesel fuel as a release agent when laying blacktop is illegal and can result in heavy fines. It also poses safety risks, as it can cause asphalt plant explosions and hot box blasts under extreme heat. Additionally, the steam produced when diesel fuel comes into contact with hot metal equipment and tools can affect its efficacy as a release agent.
To repair blacktop damaged by diesel, you can try patching the affected area with hardening asphaltic roof mastic or bagged asphalt. However, the damage is often permanent, and the only fix may be to saw cut, remove, and replace the affected area.

It causes permanent damage to blacktop by lowering its freezing point
Asphalt is a heavy petroleum product, and when diesel fuel is spilled on it, the petroleum absorbs the fuel. This causes the asphalt to soften and lowers its freezing point. This action results in permanent damage to the blacktop, as the affected area loses strength and fails, creating a pothole. The only way to fix this damage is to cut out and replace the compromised section.
Asphalt is made of bitumen, a product of fractional distillation when crude oil is split into naphtha, petrol, diesel, and other substances. Bitumen is a crucial component that binds the stones to form asphalt. When diesel fuel is used as a release agent during asphalt paving, it acts as a solvent, breaking down the bitumen and stripping it from the aggregate. This process destroys the integrity of the asphalt mix and causes the pavement to crumble and crack prematurely.
The use of diesel fuel as an asphalt release agent is not only detrimental to the pavement's longevity but also poses legal risks. The Oil Pollution Act of 1990, The Clean Water Act of 1972, and The Resource Conservation and Recovery Act prohibit contractors from using diesel fuel in this manner, with violations resulting in hefty fines.
Additionally, diesel fuel has a flash point of around 125°F. When it comes into contact with hot metal, it immediately starts to steam up and evaporate. This is problematic as a release agent because, once it evaporates, it no longer prevents build-up effectively.
The negative impact of diesel fuel on asphalt has led to the development of alternative release agents, such as PavePro, which is DOT-approved and designed to outperform diesel. PavePro Blue, for example, is a non-stripping asphalt release agent that preserves the integrity of the asphalt mix while being cost-effective and environmentally friendly.

Diesel fuel is a stripping agent, ruining the integrity of the asphalt mix
Diesel fuel is a stripping agent that ruins the integrity of the asphalt mix. It is a decent release agent, but it also acts as a solvent, breaking down the bitumen within the asphalt. This process destroys the integrity of the asphalt and the mat that is laid. Once the mix is laid, the leftover diesel fuel continues to penetrate the bitumen, separating it from the aggregate, causing crumbling, cracking, and shortening the pavement's overall lifespan.
Asphalt is made of bitumen, produced by fractional distillation when crude oil is split into naphtha, petrol, diesel, and other substances. Therefore, diesel and bitumen (asphalt) are both crude oil derivatives, with the main difference being that the chains in bitumen are much longer than in diesel. Since both are non-polar substances, the bitumen will dissolve into the diesel when they come into contact.
Diesel fuel is often used as an asphalt release agent, but this practice is ruining the pavement that is laid. Its solvency breaks the bitumen down and strips it from the aggregate very quickly. This is why it is so effective at cleaning asphalt off equipment. However, when used as a release agent, it continues to break down the oils in the asphalt mix, causing the pavement to disintegrate and shortening its lifespan.
The use of diesel fuel as an asphalt release agent also carries legal risks. The Oil Pollution Act of 1990, The Clean Water Act of 1972, and The Resource Conservation and Recovery Act all forbid contractors from using diesel fuel in this way. These acts impose hefty fines for non-compliance. Additionally, asphalt plants are now requiring proof of compliant release agents, and crews are being fined for having diesel in their sprayers.
There are alternative products available that can effectively replace diesel fuel as an asphalt release agent, such as PavePro and PavePro Blue, which are designed to outperform diesel and other asphalt products on the market. These alternatives offer better results, are cost-effective, and do not carry the same legal and performance risks as diesel fuel.

It is illegal to use diesel fuel as an asphalt release agent
Using diesel fuel as an asphalt release agent is illegal under multiple federal laws, including the Oil Pollution Act, the Clean Water Act, and the Resource Conservation and Recovery Act. These acts impose hefty fines for contractors found in violation, with penalties reaching hundreds of thousands of dollars. The primary reason for these laws is that diesel fuel poses significant environmental risks due to its petroleum-based composition.
Diesel fuel acts as a stripping agent, breaking down the bitumen in asphalt and causing it to disintegrate. This action destroys the integrity of the asphalt mix, leading to pavement failure and a shortened lifespan of the pavement. The damage caused by diesel fuel is permanent and requires costly repairs, including sawing, removing, and replacing the affected area.
In addition to its detrimental effects on asphalt, diesel fuel also poses health and safety hazards. With a flashpoint of around 130°F, diesel fuel can quickly vaporize and release dangerous gases that can combust and explode, damaging equipment and endangering workers. These explosions have occurred frequently at job sites and asphalt plants, highlighting the urgency of finding safer alternatives.
One such alternative is PavePro, a fully compliant and safe release agent. PavePro is superior to diesel fuel in terms of safety, effectiveness, and environmental friendliness. It prevents asphalt build-up, biodegrades quickly, and outperforms diesel fuel in multiple applications. PavePro is also cost-effective, requiring less product to achieve better results.
In conclusion, the use of diesel fuel as an asphalt release agent is not only illegal but also detrimental to the asphalt, costly, and hazardous. With safer and more effective alternatives available, such as PavePro, there is a pressing need for contractors to transition to compliant and environmentally friendly options. By making this switch, the industry can improve the quality of their work, enhance safety measures, and reduce their environmental impact.
