How Can PavePro be Used at an Asphalt Plant?

How Can PavePro be Used at an Asphalt Plant?

PavePro Green is used to clean asphalt from tools and equipment in many applications throughout the paving process. While PavePro is used most frequently to clean at the laydown site and after the job, there are many other applications where PavePro shines! It makes sense to integrate PavePro into operations at the asphalt plant to improve efficiency and keep equipment running smoothly. The asphalt plant is where the components (aggregate and bitumen) are first mixed to create the asphalt that will later be transported to the paving site. Asphalt is an extremely sticky substance that adheres to many surfaces on plant equipment. Applying PavePro Green to these surfaces will help keep the surfaces clean throughout the process, allowing operations at the plant to run smoothly.

Applications:

  • Shovels and wrenches: Spray or dip shovels with PavePro Green just like at paving sites. Shovels are frequently used to clean up asphalt spills, especially around the dispensing silo where the spills occur during loading. They are also used in the asphalt collection process for lab testing, as well as scooping into asphalt sampling boxes that are being tested. Wrenches and other maintenance tools used on liquid asphalt tanks can also be kept clean with PavePro.
  • Spills: Efficiently clean up liquid asphalt spills and overflows on liquid asphalt tanks by applying PavePro to the tank and surrounding area
  • Liquid asphalt lines: Unclog liquid asphalt lines that have cooled and have become clogged. PavePro should be run through the asphalt lines on a regular basis, just as it would in a distributor machine.
  • Drag slats: Clean asphalt drag slats and prevent asphalt from sticking to the chains of the slats. An automatic spray system should be set up to periodically coat the chain and the slats to clean and keep them running smoothly.

While PavePro is designed to be an asphalt cleaner, it also provides release power. PavePro’s strong release qualities leave a long-lasting film, preventing asphalt from building up quickly. This helps equipment stay durable, saves plant workers time not having to stop and clean the equipment, and saves money in the long run by preserving the machinery.

PavePro truly is a versatile solution for all of your asphalt cleaning needs!

What is the difference between Flammable and Combustible?

What is the difference between Flammable and Combustible?

The terms ‘flammable’ and ‘combustible’ are used as if they mean the same thing. However, this is not true, especially when considering the classification of materials. There are several key differences between the two workers must understand in order to ensure the highest level of safety.

The main difference between flammability and combustibility is the flashpoint. Flammable materials have flashpoints below 100 degrees Fahrenheit, while combustible materials have flashpoints above 100 degrees Fahrenheit and below 200 degrees Fahrenheit. Clearly, flammable materials have a low flashpoint, while combustible materials are much higher. However, the range for combustible materials is very wide.

Keeping the flashpoints in mind, flammable materials are much more dangerous to work with as opposed to combustible materials. However, combustible materials, while they do burn at above working temperatures, are still a hazard.

PavePro Green’s flashpoint is above 200 degrees Fahrenheit, making it the safest asphalt remover on the market, as it is neither flammable nor combustible.


 

How to Prevent Asphalt Buildup on Tires

How to Prevent Asphalt Buildup on Tires

One of the main problems that paving companies face on
a regular basis is asphalt adhering to the tires of the equipment and machinery.
Asphalt can be extremely sticky, with the degree of stickiness depending on the
difference in temperature between the surface of the newly paved asphalt and
the tires.1 Asphalt stuck on tires breaks down their integrity, adds
time to the paving job, and ultimately costs your company unnecessary money.

There are several ways to prevent asphalt from sticking on tires. To start with, paving crews must heat their tires before the job and keep them at the correct temperature. If the tire is almost as hot as the asphalt is, it acts as a “lubricant” for the rubber tires.2 Using a wheel cover is a great way to maintain heat on the tires. Wheel covers also protect tires from ambient conditions such as fluctuations in temperature, humidity, and air pressure. Another way to prevent asphalt buildup is to use a release agent. The release agent is mixed with water in the sprayer and applied directly to the tire. It is essential to operations that a release agent is applied to the tire, not a cleaner or solvent. Cleaners break down and destroy tires at a faster rate than not applyi­­­­ng anything at all. Release agents create a barrier between the asphalt and tire, preventing adhesion. Crews have to stop the job immediately when asphalt starts sticking to tires. Release agents are ideal for paving jobs because they help prevent asphalt from sticking in the first place.

Chemtek’s release agent, PavePro Blue, has been evaluated by the NTPEP and established as a high-caliber, very effective release agent. With 100% biodegradability, EPA compliance, and clean ingredients (no silicon), PavePro Blue is the most environmentally friendly and safe release agent on the market. While its main application is on tires, PavePro Blue can also be used on conveyor belts, pulleys, drum rollers, rubber tire rollers, and dump truck beds.

Paving takes time, energy, and focus – make your job easier with PavePro Blue.

Safety Improvements in the Construction Industry

Safety Improvements in the Construction Industry

National Construction Appreciation Week

In honor of National Construction Appreciation Week, we take a moment to celebrate the many safety improvements in the industry in recent years. At Chemtek, worker safety is one of the pillars we focus on with every solution we offer. Having worked closely with the road construction industry for years, we recognize the importance of keeping each worker safe. These workers have contributed to massive infrastructure growth throughout the country. The least we can do is provide them the best working conditions possible. Although there have been many safety regulations put in place aimed at protecting workers, this is a fairly new reality. Occupational safety was not always a priority, with quantity and speed taking precedence. It is estimated that over 14,000 construction workers were killed on the job in 1970. In 2009, there were only 4,340 despite the doubling of the U.S. work force!  

A major milestone on the road to worker safety was the creation of the Occupational Safety and Health Administration (OSHA) in 1971. OSHA issued standards to protect workers from hazards such as asbestos exposure, fatal falls, and electrical injuries to name a few. In 2007, employers became legally obligated to pay for all Personal Protective Equipment (PPE). Most recently, OSHA implemented a new standard to limit exposure to silica dust on construction sites.

While great strides in construction and worker safety have been made, there is still room for improvement. Construction workers are the backbone of this country and the United States’ growth and prosperity would not have been possible without them. Thank you to all employees in the construction industry for the hard work you put in every day!

Do You Need a Release Agent or a Cleaner for Your Paving Operation?

Do You Need a Release Agent or a Cleaner for Your Paving Operation?

Asphalt creates a sticky mess on every tool and piece of equipment it touches from the production process to the laydown site. There are many products on the market to help prevent asphalt from sticking to surfaces and to clean tools and equipment during and after the paving process. Knowing which solution to use in various applications for the best results can be tricky. Further complicating the decision are DOT regulations, safety implications, and environmental factors. Let’s take a closer look at asphalt release agents and asphalt cleaners, and how to determine which solution is best for your specific operation.

Release Agents

Asphalt release agents are commonly used at asphalt plants, during transport, and at the laydown site. The purpose of a release agent is to create a barrier between the asphalt and tool (or piece of equipment) to prevent adhesion. Asphalt release agents are heavily regulated by state DOTs and most must undergo evaluation by the National Transportation Product Evaluation Program (NTPEP) to ensure they do not degrade the integrity of the asphalt in any way. Release agents are typically water-based and highly dilutable. While some may form a short-term barrier to prevent asphalt adhesion, many evaporate or wear away quickly, causing hardened asphalt build-up.

Cleaners or Solvents

Asphalt cleaners or asphalt solvents are used after the asphalt has already adhered to and hardened on a surface. The purpose of an asphalt cleaner (also called a “solvent”) is to break down the asphalt so it can easily be removed from tools and equipment. Solvents are less regulated by DOTs, but are typically evaluated on how quickly and effectively they break down asphalt for easy removal. Some DOTs do not allow the use of solvents at laydown sites to avoid the risk of spills on new mat. Spilling a solvent on laid asphalt may result in potholes, as the laid asphalt is broken down by the cleaner.

Drawbacks

Both release agents and asphalt cleaners serve important functions in the paving process, and typically both products are needed for efficient, clean operations. While release agents can help in preventing some asphalt adhesion, they often fall short in totally preventing asphalt buildup and require frequent re-application, costing valuable time and resources. Asphalt cleaners, on the other hand, serve an important purpose in removing hardened asphalt. However, many solvents are composed of hazardous, flammable ingredients and pose troublesome quality control issues if spilled on freshly laid mat.

Get The Best of Both Worlds

In most paving operations, it is advisable to use an effective release agent prior to lay down and then clean any remaining build-up with an environmentally safe cleaner after paving is complete. PavePro Green is one of the few solutions on the market that offers the best of both worlds by boasting significant release power along with powerful cleaning ability. PavePro Green is designed to be an asphalt solvent, but it also leaves a slick-oily film to prevent asphalt from sticking. It also has the unique ability to be “deactivated” with water – so, if it is spilled on fresh mat, dousing it with water will deactivate its solvent power preventing quality control issues. While PavePro Green is categorized as an asphalt cleaner, its release power is longer lasting than traditional “release agents.”

PavePro Blue

Some DOTs forbid the use of asphalt solvents on the job site regardless of their ability to deactivate. In this case, PavePro Blue, Chemtek’s non-stick release agent, is the best option to use at the job site. PavePro Blue has been evaluated by NTPEP and demonstrates top-tier effectiveness as a release agent. Still, after the job is done, taking tools and equipment back to the shop to clean with PavePro Green is essential to preserve the integrity and life of your paving assets.
