When it comes to selecting an asphalt release agent, the often-overlooked factor of flash point plays a crucial role. The flash point of a material not only indicates the safety of the product (notably combustibility) but is also a vital element affecting the efficiency and release power of the cleaner. In this post, we’ll delve into what flash point means, why a low flash point can be problematic, and how PavePro, with its high flash point, stands out in the market of asphalt release agents.

In simple terms, the flash point is the lowest temperature at which an asphalt release agent turns from a liquid into a vapor. This is essentially evaporation, but the key difference is that the vapor can easily combust when ignited. For asphalt release agents, this measurement is typically done through a lab test, providing an approximation of the true flash point, and is found in Section 9 of the material’s SDS.

Problems with Low Flash Point:

Low flash points, as seen in many commonly used asphalt removers and release agents like citrus (flash point around 115°F) and diesel fuel (flash point around 130°F), present a myriad of issues. These include:

Limited Release Agent Power

Asphalt release agents with low flash points tend to evaporate quickly in hot environments, diminishing their effectiveness. When you load hot mix asphalt into the bed of a truck or stick a shovel into the mix, that asphalt is going to be hotter than the flash point of citrus and diesel and will force it to immediately begin to evaporate out. And once it has evaporated, the release agent is no longer preventing asphalt from building up.

Safety Concerns

Low flash points pose safety risks with vapors and the potential for combustion. The vapors formed from citrus release agents are toxic when inhaled and as the “flash point” name suggests, they are easily ignitable by a heat source. There are many recorded deaths, injuries, and equipment damage from citrus and diesel vapors combusting.

Decreased Efficiency

Constant re-application is required due to the rapid evaporation rate of diesel and citrus release agents, leading to a decrease in the efficiency of paving crews who spend more time applying their release agent than they do working.

Limited Release Agent Power

When build-up occurs due to poor asphalt release agent performance, cold, hard chunks of asphalt can move through your paving machine and shuttle buggy and cause damage to sensitive parts of the machine like the moving components.

Benefits of Asphalt Release Agents Like PavePro:

Choosing an asphalt release agent with a high flash point, like PavePro with a closed-cup flash point well over 400 degrees Fahrenheit, brings several advantages:

Long-Lasting Efficiency and Cost Savings

A high flash point ensures the release agent lasts longer, reducing the need for frequent re-application and allowing your road crew to continue their work without interruptions or build-up. With less frequent application, PavePro proves to be a cost-effective solution, saving on both product usage and expenses.

Great Cleaner

PavePro excels not only as a release agent but also as an effective cleaner for asphalt, allowing for the easy removal of already hardened asphalt, tack overspray, and other build-ups. PavePro’s high KB value enables it to penetrate deep into hardened asphalt, ensuring thorough cleaning.

Legal To Use

Because PavePro is not petroleum-based, it is legal to use as a release agent in all 50 states in the US. If you are required to use a DOT-approved release agent in your truck bed because you’re on a state-DOT job site, we have those products available too.

Unlike diesel fuel, which is illegal to use as a release agent, and citrus, which is considered hazardous waste, PavePro can be used anywhere and on anything without penalty.

Biodegradable & Safe For Workers

Because you have to be nowadays, PavePro is 100% biodegradable, non-toxic, non-hazardous, and safe for workers.

Amazing Lubricant

PavePro’s unique formulation includes lubricating properties and helps to protect delicate moving parts in asphalt equipment. In fact, after a few years of internal testing with our customers, we have found an over 60% decrease in downtime caused by wear and tear on patch trucks and shuttle buggies.

Water Deactivated

It deactivates with water, providing a safe and easy cleanup process. In addition to this, if you spill PavePro on a fresh mat, you can hit it with some water and you won’t have to mill and repave that area or worry about rutting or future pavement issues.

Understanding the significance of flash points in asphalt release agents is crucial for both safety and efficiency. Opting for PavePro as your asphalt release agent not only mitigates safety risks associated with low flash point alternatives but also brings extended-release power and cost savings. Make the smart choice for your paving operations with PavePro’s superior performance.
