ASPHALT PAVEMENT ALLIANCE ANNOUNCES WINNERS OF 2019 PERPETUAL PAVEMENT AWARD

A record number of 12 departments of transportation honored for success of long-life asphalt roads.

ORANGE PARK, Florida – Twelve departments of transportation (DOTs) were named winners of the 2019 Perpetual Pavement Award (PPA) by the Asphalt Pavement Alliance (APA). This is a record number of PPAs awarded in a single year since the awards were first presented in 2001. The award celebrates long-life asphalt pavements that reflect the characteristics of a Perpetual Pavement design.

The award is presented to state DOTs and local agency road owners for well-performing asphalt pavements that are at least 35 years old with proven high-quality structural design. To earn the award, the pavement must have not suffered a structural failure, and it should have an average interval between resurfacing of no less than 13 years. The pavement must demonstrate the characteristics expected from long-life, Perpetual Pavement design: excellence in design, quality in construction and value to taxpayers.

Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University evaluated the nominations and validated the results for the 12 Perpetual Pavement Award winners for 2019. Since the PPA was first presented in 2001, 144 pavements in 31 U.S. states and one Canadian province have been honored with the award.

A New Normal: How McElroy Manufacturing Is Dealing With COVID-19

“It was like a week of Mondays.”

That’s how Sharon McElroy summed up what it felt like to head into the office to tackle an ever-changing set of challenging circumstances in the first few days of the COVID-19 pandemic.

From responding to the latest news and addressing employee concerns, to developing policies and communicating updated governmental guidelines, the vice president of marketing for Tulsa, Oklahoma-based AEM member company McElroy Manufacturing, Inc. and her fellow company leaders found themselves in an unenviable position seemingly overnight.

The task was clear – provide stability in an increasingly uncertain situation. But how exactly? While the seriousness of COVID-19 was becoming readily apparent, information and guidelines related to the growing pandemic were changing daily by mid-March. Further complicating matters, a significant number of McElroy employees were coming off a successful trade show run at CONEXPO-CON/AGG in Las Vegas, and were in the process of returning to Tulsa, right as elected officials began issuing their initial guidelines and mandates in response to COVID-19.

“It was like coming home to find out the world had changed,” said Sharon McElroy.

FOSTERING STABILITY IN A TIME OF UNCERTAINTY

Three weeks later, everything has changed for McElroy, the company’s employees, and its customers.

“I feel like we are all living in some unreal Hollywood movie,” said Chip McElroy, the company’s president and CEO in a March 25 letter to staff. “From the chaos, the sensationalism, the ever-changing stream of directives, the loss of freedoms and the raw emotions we are all feeling, I have a deep appreciation for the stress and anxiety that all of us are living with as we work our way through this odyssey.”

Fostering organizational stability during a global pandemic has been a challenging and, at times, hectic undertaking for McElroy. And it’s not difficult to understand why. Every company – whether large or small – is comprised of a diverse set of employees, all of whom possess different personalities, backgrounds and skillsets. McElroy is no different. So, when COVID-19 began to upend the company’s day-to-day activities and processes, company leaders were quick to recognize staff members would have a wide range of responses to the growing public health crisis.

Some employees are quite fearful, especially those with families. Others are far less concerned. What’s universally consistent among McElroy employees, however, is a willingness to listen to what’s communicated by company leaders and – perhaps more importantly – comply with newly formed company policies to ensure the safety and well-being of everyone.

ACCEPTING A “NEW NORMAL”

The “new normal” brought on by the spread of COVID-19 has required a shift in culture for McElroy. The company is proud of its tight-knit staff, but now everyone and everything feels much more spread out due to social distancing guidelines.

Employees who are able to telecommute alternate days spent in the office and at home to ensure the fewest possible number of people are in the same place at any given time. Conference rooms, once occupied by large groups engaging in regularly held meetings, now face strict occupancy limits. Video conferencing has become a primary mode of communication, much like it has for other organizations and businesses around the country.

“As a manufacturing company, we don’t do a whole lot of remote work,” explained Sharon McElroy. “We’re family-oriented, and we’ve always embraced a philosophy of being ‘One team, one company.’”

Many within the organization can’t help but wonder when it will be safe or appropriate to conduct certain tasks and responsibilities again, when everyone can return to work at the same time, or when the company’s focus will fully return toward providing valuable products and services for customers. So much has changed in such a short time, leaving everyone to adjust accordingly as quickly as possible.

“I feel like we’re also just trying to communicate with customers that we’re still in business and we can help them,” said Sharon McElroy.

LESSONS LEARNED

Times of crisis often lead to lessons learned in a matter of only a few days and weeks. McElroy Manufacturing’s leaders appreciate the importance of good communication and transparency now more than ever – both with their employees and with their customers.

“We’ve always had a culture of open communication and this crisis brings the importance of that to a whole new level.” said Sharon McElroy. “It’s a lesson that we will remember.”

The company has also taken great care to ensure employees know they will be taken care of during these unprecedented times. Whether it’s through providing additional sick time, adjustments to pay structure, or implementing safety precautions and procedures related to social distancing, hand-washing, limiting group sizes or regular disinfecting, organizational leaders are doing whatever they can to provide as much stability as possible. Because, ultimately, the goal is to ensure McElroy’s workforce knows it’s safe, secure and valued when at work and on the job.

According to Sharon McElroy, the emphasis on communication and transparency has made navigating the current COVID-19 health crisis much easier for employees at the company, and it’s certainly helped limit unnecessary panic or concern. However, despite the best efforts of everyone at McElroy, uncertainty regarding the future still remains.

“I think people feel pretty secure, but the uneasiness for me comes from ‘How long is it going to last?’” she said. “Sometimes you need that ending to look toward. And when you don’t have it, honestly, it’s tough.”

Aquajet Launches Ecosilence 3.0 For Quiet Operation and Reduced Fuel Consumption

Aquajet’s new Ecosilence 3.0 offers a number of innovations including an integrated, low-emission engine with the latest technology and a liquid-to-air cooling system. It employs auto start/stop technology, which temporarily shuts down the engine when not in operation, reducing idling as much as 50%.

Aquajet, a global leader in manufacturing Hydrodemolition machines, introduces the Ecosilence 3.0 that reduces noise and allows for a more compact jobsite, while enhancing environmental stewardship and lowering overall operating costs. The new Ecosilence features integrated auto start/stop technology that improves fuel consumption, which saves as much as 6.6 gallons ( 25 liters) fuel a day for a smaller carbon footprint. The re-engineered Ecosilence is more compact, as well, with the entire self-contained system now fitting in a standard, 20-foot shipping container. It also produces less noise while in operation, making it ideal for use in urban areas with limited space and strict noise restrictions. The new unit also has dramatically improved pumping pressure, operating as high as 43,511 psi (3,000 bar), and providing ample power for Hydrodemolition applications such as concrete renovation and road and bridge repair.

“The original Ecosilence achieved the low noise levels our customers needed but could not match the power of our standard Power Pack, which was necessary for certain applications,” said Roger Simonsson, Aquajet managing director. “We knew we could do better, so our engineers went back to the drawing board to provide the best of both worlds — power and quiet operation. Along the way, we were able to incorporate the latest automatic technology and take 3 feet off the overall length for a brand-new Ecosilence.”

The self-contained Ecosilence 3.0 fits in a 20-foot container size for easier transportation, while maintaining ample space for a work bench, tools, hose storage and an Aqua Cutter Hydrodemolition robot. The container has an innovative sound-absorbing design to reduce noise.

The Ecosilence 3.0 features an environmentally friendly, low-emission engine and high-pressure pump to power Aquajet’s range of Aqua Cutter Hydrodemolition robots. The skid-mounted unit employs auto start/stop technology, like that found in many modern automobiles, which temporarily shuts down the engine when not in operation to reduce idling time by up to 50%. The engine automatically starts up when operation resumes. In this way, the new Ecosilence saves money and significantly reduces emissions. The integrated engine and high-pressure pump unit pairs with a state-of-the-art liquid-to-air heat exchanger to provide quiet, efficient operation for all Hydrodemolition applications.

The new, skid-mounted engine and pump are isolated and heat regulated in a sealed compartment at the front of the container, limiting noise to allow operation in urban areas and other noise-sensitive environments. This innovative design also prevents debris or outside air from entering the engine chamber during operation. Because of this, the new Ecosilence can be used in harsh environments such as harbors or cold weather without negative effects. 

“Aquajet always strives to provide innovative solutions that meet our customers’ challenges head on,” Simonsson said. “The Ecosilence 3.0’s key features are the result of these customer-driven answers. For example, a contractor working in a harbor struggled with fog filling the unit because the engine was exposed to the cold, wet air. By isolating the engine and pump, the new unit eliminates these challenges.”

The new Ecosilence features integrated auto start/stop technology which temporarily shuts down the engine when not in operation to reduce idling time by up to 50% and improve fuel consumption by as much as 25 liters (6.6 gallons) of fuel a day.
 

Like all previous Aqua Power Packs, the Ecosilence 3.0 is easy to transport and set up. It measures 20 feet by 8 feet by 8.5 feet ( 6.1 meters by 2.4 meters by 2.6 meters) maintaining innovative sound-absorbing design features. This includes insulated walls and doors, as well as seals on all doors and hatches. Despite the shorter overall length, the container still provides ample storage for the company’s Aqua Cutter robots, accessories and tools. Additional options are available to customize this work area, such as a built-in workbench with a vise that provides contractors a space for jobsite maintenance and a place to store spare parts. 

The Ecosilence 3.0 is available in several pressure and flow combinations, allowing operators to scale equipment to meet their specific needs. To help contractors select the ideal unit, the company launched a new online tool, the Aquajet Configurator,  that walks operators through a number of standard and optional features for a totally customized Ecosilence 3.0.
