Reducing Material Costs by Integrating Smarter Solutions

Reducing Material Costs by Integrating Smarter Solutions

Producing quality work while limiting costs is a daily challenge for all paving and road construction contractors. Projects must be completed efficiently without compromising on quality. Chemtek, Inc. provides innovative solutions that improve efficiency, reduce material costs, and are safe for the environment and worker reducing risk and limiting the potential for EPA and OSHA fines. Let’s take a look at how two of our products in particular- NeSilex and PavePro – are smart solutions to improve operations and reduce costs.


Reducing respirable silica dust is a major concern in the construction industry today. Respirable silica dust is an extreme safety hazard for workers and surrounding civilians. Water delivery systems are commonly used to control dust at job sites; however, one of the main drawbacks of using water alone for silica dust suppression is the amount of water needed for effective dust control. A study by NAPA found that in milling operations, water output had to be more than doubled to achieve a respirable dust level below OSHA’s permissible exposure limit. Material, labor, and transportation costs associated with doubling water output in milling machines and in other dust producing activities are significant. Increasing water usage at the construction site also creates more slurry and can lead to additional clean-up costs. OSHA has mandated that construction companies address respirable silica dust hazards, but simply drowning the problem with more water is both ineffective and inefficient!

NeSilex, a silica dust suppressant, was designed to be added to existing water systems to make water more efficient and effective at controlling respirable silica dust. NeSilex drastically cuts down the amount of water needed for respirable silica dust suppression. By chemically changing the composition of water droplets, the silica dust particles are attracted to the water, as opposed to being repelled by it. The water then encapsulates the harmful particles, keeping them from becoming airborne. The power of the chemically altered water particles is so strong, less water is needed to suppress silica dust.

A little product goes a long way! Only a small amount of NeSilex is needed to alter hundreds of gallons of water providing effective dust control. Eliminate the threat of OSHA fines due to silica dust, reduce the amount of water needed for effective dust control, and prevent pesky slurry issues by integrating NeSilex into your operations

PavePro Green

Asphalt build up on tools and equipment is inevitable in the paving industry. A good release agent and cleaner can provide tremendous labor cost savings and improve machine operations and efficiency. Unfortunately, many cleaners and release agents simply do not work well and most carry additional hazards with high flammability and low biodegradability.  Diesel fuel, the trusted industry standard for asphalt removal has been illegal for use as an asphalt cleaner for over 20 years. Citrus alternatives are considered RCRA hazardous wastes and boast very little (if any) release power. Additionally, citrus cleaners have a high evaporation rate which means hot paving environments require constant product reapplication. The threat of fines and associated hazards of using either citrus or diesel for asphalt removal coupled with the amount of product needed to get effective cleaning or release power make these inefficient solutions.

PavePro is the most efficient and effective solution for asphalt removal. Its high evaporation rate allows it to work harder and longer than competitive solutions. It boasts twice the cleaning power of alternatives and tackles the toughest polymer-based asphalt mixes with ease. The high evaporation rate of PavePro allows it to leave a thick, oily film on tools and equipment preventing asphalt build up over a long period of time. In a hot-mix shovel test, PavePro kept asphalt from building up for well over 50 shovels of asphalt. When the same shovel was pre-treated with a citrus alternative or diesel fuel noticeable build up occurred after only 37 and 35 shovels of asphalt, respectively. Reducing product re-application offers significant product and labor cost savings. As an added bonus, PavePro 100% biodegradable and safe to use reducing the risk of fines.

A hidden cost of keeping asphalt cleaners like citrus or diesel fuel, at a construction site is the potential for costly spills. If one of these products is spilled on freshly laid mat, the only choice is to mill up the asphalt and re-pave. PavePro offers a unique benefit that eliminates this risk. The cleaning power of PavePro can be deactivated with water, if PavePro is accidently spilled on paved road, douse the area with water and no asphalt degradation will occur.

With labor and cleanup constituting a large portion of construction costs, it makes sense to choose PavePro  – a highly concentrated solution that needs only one application to thoroughly remove built up asphalt while also preventing asphalt from re-adhering. Save money by using less product over time and increase worker efficiency with fewer reapplications.


Managing construction sites and projects is challenging. Let us help you improve efficiency WHILE reducing costs. Our products, NeSilex and PavePro, truly provide the best value while saving precious time and money.

Drawbacks of Using Citrus to Remove Asphalt

Drawbacks of Using Citrus to Remove Asphalt


PavePro is the industry leading solution for removing asphalt from paving tools and equipment, but PavePro isn’t the only asphalt cleaner on the market. Many asphalt removers are citrus-based. PavePro contains no citrus so let’s look at how it stacks up against citrus alternatives.

Safety, Flashpoint & Flammability

When considering flashpoint and flammability, the difference in safety between citrus-based cleaners and PavePro is profound. While citrus cleaners have not been banned for use by the EPA (like diesel fuel), they are considered a RCRA (Resource Conservation & Recovery Act) hazardous waste. RCRA classifies a hazardous waste as any material that has a flashpoint below 140°. Citrus products’ flashpoint is typically 115°F, putting it well below the threshold.

A flashpoint of 115° F or lower also means the material is combustible. Working with asphalt especially in high heat, is dangerous. The danger is compounded by handling hazardous citrus substances that could ignite when 115° F is reached. Ignitions ranging from smaller, equipment-based incidents to large-scale asphalt plant explosions are real possibilities when handling citrus products. With a flashpoint over 200° F, PavePro is neither combustible nor flammable. PavePro eliminates the risks of flashpoint-related accidents and is the safest solution removing asphalt from paving equipment in the field and at the shop.

Another area of concern for many citrus-based cleaners is the additional additives needed to boost cleaning power. Many citrus cleaners include environmental disrupters and carcinogens to add additional cleaning power, but are the advantages worth the cost? Let’s take a look! 2-butoxyethanol (butyl) is found in many powerful citrus solvents; unfortunately, butyl is a known carcinogen that causes harm when inhaled and exposed to the skin. Exposure to butyl can lead to cancer, leukemia, and other serious diseases. Some citrus cleaners also contain nonylphenols which is type of alkylphenol ethoxylate (APE). APEs are an environmental hazard and known as “endocrine disrupters.” When APEs enter a water source they can poison fish, altering their reproductive system. Both butyl and APEs present serious dangers and it’s important to ensure workers are not exposed to these hazards. PavePro Green is an environmentally safe product that contains absolutely no hazardous ingredients. While it boasts impressive cleaning power, it doesn’t contain the hazardous additives found in many competitive products.

Cleaning Power

Cleaning power is what makes an asphalt remover valuable to a paving crew – an efficient asphalt cleaner reduces labor costs, material costs, and equipment repairs. Citrus cleaners are less than half as effective at removing asphalt from equipment and machinery than PavePro. While citrus-based cleaners do have powerful cleaning capabilities and tend to clean quickly, the low flashpoint leads to a high evaporation rate. This means more product is required and constant re-application is needed. PavePro’s high flashpoint and slow evaporation rate allow it work harder and longer to remove tough asphalt build-up. Less product is needed, and labor hours aren’t wasted on re-application efforts.

Release Qualities

Citrus-based cleaners also do not possess release qualities. Applying them to tools or equipment to generate release is futile due to the high evaporation rate. As soon as hot asphalt hits the cleaner, it evaporates. No film is left behind to protect the equipment or machinery from asphalt buildup. Essentially, asphalt will continue accumulating and multiple reapplications will be necessary. In contrast, PavePro Green, has unique release qualities that allow more than 50 shovels of asphalt before noticeable asphalt build-up occurs. These release qualities enhance PavePro’s effectiveness and superiority, saving your crew time and your company money.


            The price of citrus-based cleaners fluctuates based on the market-price of orange oil which is relatively unstable. Generally, citrus-based cleaners require larger margins to cover these raw material fluctuations meaning the price is high for the quality of product being supplied. PavePro’s price is not dependent on raw material cost fluctuations which allows for a competitive and stable pricing structure.


            Citrus-based asphalt cleaners pale in comparison to PavePro when examining effectiveness, safety, and overall quality. Choose the option that works harder and longer, while protecting your crew and the environment.
