November 10, 2015 T. Carter Ross, (888) 468-6499

Lanham, Md. — Nationwide, asphalt pavement mix producers continue to improve the sustainability profile of America’s roads through the incorporation of recycled materials and the use of energy-saving warm-mix asphalt technologies.
According to the latest survey of asphalt mix producers conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), more than 75 million tons of recycled materials — primarily asphalt pavement material reclaimed from old roads and parking lots and recycled asphalt roofing shingles — was put to use in new asphalt pavement mixtures during the 2014 construction season.

Led by Germanna, a new statewide effort will partner The Virginia Asphalt Association, the Virginia Department of Transportation and the Virginia Community College System to establish the Virginia Education Center for Asphalt Technology.   “Germanna is pleased to partner with the Virginia Asphalt Association in developing these vital certifications and apprenticeships,” said Germanna President David A. Sam. “The commonwealth needs people with the skills to pave, inspect and repair our roadways. And citizens of Virginia need well-paid jobs that make a difference. Our work together in developing these programs helps to close that skills gap and make for a better Virginia.”

Secretary of the Commonwealth Levar Stoney made the announcement Monday at the Jefferson Hotel in Richmond. “Whether you’re in Abingdon or Arlington, students will now have the ability to further their careers in one of Virginia’s key industries,” Stoney said. “The efforts of this partnership will send a signal to all our competitors that we know what it takes to continue building the new Virginia economy.”

Germanna spokesman Mike Zitz said the effort will be focused at Germanna with changes to the asphalt-related materials certification classes, the initiation of an asphalt technologist apprenticeship program and eventually an asphalt technologist associate’s degree.

$12.9 billion in road, bridge rail and public transportation improvements; public hearings to be held

RICHMOND – The Commonwealth Transportation Board (CTB) released today the draft Six-Year Improvement Program (SYIP), which allocates $12.9 billion to transportation projects over the next six fiscal years beginning July 1, 2015.  Projects include highway, road, bridge, rail, transit, bicycle/pedestrian paths and other transportation improvements across the state.

The SYIP supports nearly 3,000 transportation projects to improve the state’s infrastructure.   The draft program does not include new projects that would be subject to scoring under the new prioritization process under House Bill 2 (HB2). This process will help determine critical transportation needs through a fair and objective analysis.

Governor Terry McAuliffe signed HB2 into law in 2014, which directs the CTB to develop and use a scoring process for project selection by July 2016. Candidate projects will be screened to determine if they qualify to be scored. Projects will be scored based on an objective and fair analysis applied statewide. The law will improve transparency and accountability. The public will know how projects scored and the decisions behind the CTB’s project selections.

Recycle Tax Credit Amended 

reduce-reuse-recycleThe 2015 General Assembly passed an amended Tax Credit Reduction regulation that many members have previously taken advantage of (since the 1990’s) when purchasing equipment or machinery related to the use of RAP.  The Governor approved the modifications to the rule several weeks ago.  The changes are beneficial to industry.  The tax credit has been upped from 10% to 20% and purchased equipment and machinery eligible for the credit now only has to be used “predominately” for recycling activities at the plant site instead of “exclusively”.  The program has also been extended to 2025.  The changes may open the door to getting the credit for things such as equipment used to manage RAP stock piles that may have other functions onsite.  Things like RAP crushers and conveyors as well as components of the plant that are part of the production process utilizing RAP have already been approved by DEQ as eligible.  Grey areas on some equipment may be helped by the change to “predominately”.  If in doubt, members should send it in to DEQ and see if they will approve it.  The new rules are retroactive until January 1, 2015.

To view the amended regulation go to  The application process for submitting tax credit requests can be found on the VAA web site under the members only environmental section (waste issues).  DEQ will probably be updating the procedures soon to incorporate the amended regulation.

     Improve Pavement Scoping With PaveXpress,        New NCAT Guidance
Web-Based Tool Supports Recommended Recalibration of
AASHTO 93 Structural Layer Coefficient for Better Designs

For More Information, Contact:
T. Carter Ross at 301-731-4748

The National Center for Asphalt Technology (NCAT) recently released guidance on recalibrating the structural asphalt layer coefficient in the AASHTO 1993 Design Guide. The AASHTO 93 design methods are based on empirical data gathered in road tests from 1958 to 1960. Although newer mechanistic-empirical design methods have been developed, 78 percent of U.S. states predominately use empirical design methods. However, it is commonly recognized that the AASHTO 93 design method tends to result in an overdesign of pavement thicknesses for high traffic levels, which can add unnecessarily to the cost of a pavement.

Civil Penalty When Uninsured For Workers’ Compensation Will Significantly Increase Effective July 1, 2014

Richmond, Virginia, May 21, 2014:  The 2014 General Assembly approved an increase in the civil penalty imposed when an employer required to insure under the Workers’ Compensation Act fails to insure.  An employer is required by state law to insure in Virginia when they regularly employ more than two part-time (or full-time) employees.  A business that hires subcontractors or other business to assist them in their trade or to fulfill a contract must count the subcontractor’s employees as well as their own employees in determining total employees for coverage requirements.  For a contractor whose work varies, the Commission looks to the “established mode” of performing work.  A contractor that hires one or more subcontractors with employees to accomplish their business is required to carry workers’ compensation insurance.

Barton S. Mitchell Dies

Reprinted from The Baltimore Sun, by Frederick N. Rasmussen on October 09, 2013 

Barton S. Mitchell, a retired asphalt paving company executive who was active in Maryland Republican politics and enjoyed collecting vintage cars, died Sunday of lung cancer at his Lutherville home. He was 73.

“Bart was just a larger-than-life character who sucked all the air out of the room and loved playing the part of the ‘Big Cheeeze,’ which those who knew him called him. Everything with Bart was big, big, and I will miss him,” said former Gov. Robert L. Ehrlich Jr., a longtime friend.

“Maryland will miss him, and thousands of his friends will miss him. He was passionate about his hobbies, the family business and his friends. He was always a condition-less friend,” said Mr. Ehrlich.

“Bart was in money circles. That’s what he did. He raised money,” said Helen Delich Bentley, the former congresswoman and chairman of the Federal Maritime Commission.

“He was interested in getting more people in office and he felt very strongly that it was important for the country to have a strong two-party system, and he gave his all to get us there,” said Mrs. Bentley, who added that Mr. Mitchell worked with Jim Knott to raise money on several of her campaigns.

“He was big in stature and had broad shoulders. He sort of took over a room whenever he came into it, and he always did a good job,” said Mrs. Bentley.

The son of E. Stewart Mitchell and Irene Barton Mitchell, Barton Stewart Mitchell was born in Baltimore and raised on Bellemore Road in Roland Park.

After graduating from McDonogh School in 1958, he earned a bachelor’s degree in 1962 from Washington & Lee University, where he was a member of Phi Kappa Psi fraternity.

After graduation, Mr. Mitchell served in the Coast Guard for six months before joining the family asphalt business, E. Stewart Mitchell Inc., which had been established by his father in 1941 on Ridgewood Avenue in Northwest Baltimore. The company became a leading marketer, transporter and applier of all types of liquid asphalt.

Mr. Mitchell was 28 when he took over the company in 1968 after his father’s death.

In addition to E. Mitchell Stewart Inc., Mr. Mitchell had owned or controlled the Bituminous Emulsion Co., MDG Inc., Mitchell Industries Inc. and Montgomery Construction Inc.

In 1976, Mr. Mitchell and two partners, Bob Surface and Ron White, established Superior Paving Corp. in Gainesville, Va., which has grown to be the leading hot-mix paving firm in Northern Virginia. It operates nine hot-mix plants and a 10th through an affiliated plant.

“I guess I first met Bart about 1969 or 1970. I was working for a paving company in Fairfax, and we were buying our liquid asphalt from his company in Baltimore,” said Mr. Surface.

“So we started Superior Paving Corp. in 1976, and have gotten along fine and dandy ever since then,” said Mr. Surface, who is now retired from the company.

“Bart was a studious thinker and a visionary. He was very much a micro-management guy who had a head for the minutiae,” said Mr. White, former chairman and CEO of Superior, who is now vice chairman. “He always saw the big picture and put together the strategy to get us there. He was a big presence among our employees, who very much liked him.”

Mr. White said his partner easily took control of a situation.

“People always paid attention to what Bart had to say. He was such a great partner, and no one could have anyone better to provide the leadership to get us down the path,” he said.

Mr. Mitchell retired in 1995 and handed E. Stewart Mitchell Inc. to his son, David Mitchell of Severna Park, who operated the business until closing it in 2011.

Another son, James Mitchell of Warrenton, Va., is now the president of Superior Paving, while Mr. Surface’s son, Frank Surface, is CEO.

In 1983, Mr. Mitchell, who had been cooperating with state and federal officials investigating Maryland highway contracts, was sentenced to several months in prison after pleading guilty to conspiracy in a bid-rigging scheme.

Mr. Mitchell “was the key event, the way the investigation got off the ground,” a source who was close to the investigation told The Baltimore Sun in a 1983 article. “Without his participation, [federal and state] investigators would have nothing.”

Mr. Mitchell was a past president of the Maryland Asphalt Association and the Maryland Highway Contractors. In 1981, he was named to the board and later served as chairman of the National Asphalt Pavement Association. He was inducted into its Hall of Fame in 2010.

Mr. Mitchell had served as an officer, including president, of the Baltimore Skipjacks minor-league ice hockey franchise for 14 years, and had been the owner of Southern Maryland Marine.

He served on the boards of Roland Park Country School and Boys’ Latin School.

Mr. Mitchell had long been active in Maryland Republican politics, fundraising and working on campaigns.


NAPA Young Leaders Award Scholarship

On September 11th and 12th the NAPA Young Leaders held their 10th annual conference at the W Hotel in Washington, D.C. This year the Young Leaders co-located their meeting with NAPA’s Asphalt Fly-In. Attendees participated in all Fly-In activities, including legislative and regulatory briefings, networking events with members of Congress, and lobbying visits.

The Young Leaders Conferences always have sessions focused on developing and building the leadership skills needed for personal and professional growth.  To prove that commitment, each year NAPA Young Leaders presents a scholarship to a graduate or undergraduate student who is working towards a degree in Civil Engineering, Construction Management, or Construction Engineering in the state in which the meeting is held.

This year we were able to award the scholarship to a student in our great state of Virginia.  The VAA and its Board of Directors stepped up to the plate and increased the scholarship to a record $5,000.  We saw 23 applications come through all of which deserving of this award.  The scholarship was awarded to James Bryce of Virginia Tech.  He received his masters of Science and Engineering in 2012 and is currently working on his PhD.  James has a long list of academic achievements and is also very active in his community.  James has conducted research with the Center for Sustainable Transportation Infrastructure at the Virginia Tech Transportation Institute (VTTI), VDOT, the Strategic Highway Research Program 2 (SHRP 2), and a national Sustainable Pavements Consortium.

We congratulate Mr. Bryce on receiving this scholarship.  Through this scholarship, Virginia is a seen as a state that recognizes the value in making the necessary investments to ensure the future success of our industry.

Virginia Receives $57.3 Million in ‘Bonus’ Funding to Accelerate Transportation Projects
Additional funding originally allocated to other states will go toward transportation projects in Virginia 

RICHMOND — Governor Bob McDonnell today announced that the Commonwealth of Virginia has received an additional $57.3 million in federal funds for transportation originally allocated to other states.

The Virginia Department of Transportation (VDOT) will use this additional funding for paving projects in each of its nine construction districts: $16.7 million will go toward interstate paving, $25.6 million is designated for paving primary roads and $13.7 million is allocated for paving secondary roads. Additionally, $1.3 million is slated for bridge painting/preventative maintenance. Later this month, VDOT will make its recommendation to the Commonwealth Transportation Board, which has final approval on how money is spent on transportation projects.

“This has been a historic year for transportation funding in Virginia,” said Governor McDonnell. “This ‘bonus’ funding, along with the new and sustainable funding from the transportation bill, will enhance VDOT’s ability to move projects forward and continue to improve the condition of our roads. Virginia’s transportation system is vital to both economic opportunity and to the quality of life of every Virginian.  These strategic investments will mean shorter commutes, new roads and more jobs across the Commonwealth.”

Each September, the FHWA reviews every state’s ability to commit allocated highway dollars as the federal fiscal year ends. States that cannot obligate federal funding must return that spending authority to the FHWA. The funds are then redistributed to states that can obligate all of their federal allocations and have additional eligible projects ready to move forward.

OSHA Proposes New Standard for Crystaline Silica

The proposed respiratory standard for respirable silica dust is being set at 50 micrograms per cubic meter.  The Occupational Safety and Health Administration (OSHA) offers a “flexible alternative” compliance path for construction activities such as pavement milling to achieve the standard. The asphalt industry has taken steps to protect its workers through a partnership with the National Institute for Occupational Safety and Health (NIOSH).  Most milling equipment has continuous water feed systems installed that prevent the generation of dust during operations and so long as there is no visible respirable dust, workers do not have to wear protective gear unless they work over a 4 hour shift.  The National Asphalt Pavement Association is continuing to work with NIOSH through the partnership process to obtain additional information on the exposure risks to workers in the milling operations area and believes that with the safeguards present on milling machines, it can demonstrate that there are no silica exposure risks (levels maintained below the standard).  For more information members can go to the members only, safety section of this website.
