Every Day Is Earth Day With AsphaltIn time for Earth Day, NAPA

and FHWA have released a new survey of sustainable construction practices in the asphalt pavement industry. The survey, which covers the 2011 construction season, studies the use of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and warm-mix asphalt (WMA). The use of recycled materials in asphalt pavements saved taxpayers more than $2.2 billion dollars during the 2011 paving season.

According to the survey, about 3.7 million tons of liquid asphalt binder were saved through the use of RAP and RAS during 2011. Also, about 19 percent of all asphalt produced in the country that year was made using WMA.

In 2011, RAP usage reached 66.7 million tons, a 7 percent increase from 2010 and a 19 percent increase from 2009. More than 99 percent of asphalt pavement reclaimed from roads was collected for use in new pavements. In the survey, 98 percent of producers reported using RAP in their mixes for new

construction, pavement preservation, rehabilitation, and other projects.

RAS usage also continued to climb, increasing to 1.2 million tons in 2011 - an 8 percent increase over 2010, and a 52.5 percent increase since 2009. Since 2009, RAS usage has been reported in 36 states. RAS includes both manufacturers’ scrap shingles and post-consumer roofing shingles.

In 2011, total WMA tonnage in the U.S. was estimated at about 69 million tons, a 67 percent increase from 2010 and a nearly 309 percent increase since 2009. About 96 percent of the WMA in the U.S. was produced using a foaming process; warm-mix additive technologies accounted for a little more than 4 percent of the market.

The survey was conducted in mid-2012. Results from 203 companies with 1,091 plants in 49 states and Puerto Rico, along with data from 32 State Asphalt Pavement Associations, were used to calculate industry estimates for total tonnage. A copy of the full

survey, including a state-by-state breakdown of the data, is available at AsphaltPavement.org.

2013 Environmental TrainingEnvironmental Training was held

April 16th and was a joint effort between the MN Pollution Control Agency (MPCA), Wenck Associates, and MAPA.

Topics included air permits, storage tanks, spill prevention plans, stormwater permits, aggregate mining permits, wetland and watershed topics, and compliance. Thank you to all who participated!

Pavement Smoothness MattersExperts say that vehicles consume

less fuel when traveling on smoother pavements. This makes sense intuitively. And, lower consumption of fuel conserves natural resources for a healthier environment.

There have been claims from the competition that concrete pavements save fuel. However, because 94 percent of America’s roadways are surfaced with asphalt, it is diffi cult to directly compare asphalt pavements to concrete pavements.

A meaningful comparison would require data from a tightly controlled experiment. Differences in traffi c fl ow, terrain, smoothness, wind, temperature, tire infl ation pressure, driver behavior, and a host of other factors must be accounted for in the results.

Over the years, the competition has sponsored research projects to study the effect of pavement type (concrete vs. asphalt) on vehicle fuel consumption. A critical review of these studies, however, reveals that the results are based upon comparisons of apples and oranges – the pavements studied are not equivalent. More importantly, the results of these studies reinforce the well-established fact, consistent with the WesTrack project, that pavement roughness, not pavement type, is responsible for differences in vehicle fuel consumption.

Nearly all states, including Minnesota, have smoothness standards for newly built roads. If the road does not meet the standard, the contractor’s pay is reduced. Some states have different standards for asphalt and concrete, and in every state where this is the case (MN included), the requirements for asphalt roads are more stringent than for concrete roads.

As noted in a 1999 General Accounting Offi ce report to Congress, “Concrete roads may produce rougher readings than asphalt roads, even if the concrete road is of very high quality. Features such as joints between sections can contribute to the roughness of concrete highways.”

Keeping a road smooth begins with a well-engineered foundation and pavement structure. An asphalt “perpetual pavement” is designed and built to ensure that the structure lasts virtually indefi nitely. Restoration is simply a matter of infrequent overlay or milling with an overlay of the surface with asphalt pavement that includes the recycled millings.

Not surprisingly, these periodic improvements in ride quality signifi cantly reduce fuel consumption of vehicles traveling these roads and protect the pavement structure. Bottom line: asphalt pavements are easier to maintain and keep smooth.

Americans burn 175 billion gallons of fuel driving 3 trillion miles a year. If we could make the roads across the nation slightly smoother, we could likely save at least 4 percent of the fuel consumed. This could reduce annual vehicle fuel consumption by about 7 billion gallons, equivalent to taking over 10 million vehicles off the road every year. This would reduce the amount of fuel and vehicle maintenance required for every traveler on our roads, in addition to conserving our natural resources and benefi ting our environment.

After closely examining the available research and investigating a variety of different factors, one thing is clear: of all pavement characteristics, smoothness is the major determinant of vehicle fuel economy. Simply stated, the smoother the pavement, the less fuel consumed by the vehicle. For a full discussion of studies on this topic, see the below-referenced article.

Marks, Howard, PhD. 2009. Smoothness Matters: The Infl uence of Pavement on Fuel Consumption. Hot Mix Asphalt Technology Vol. 14, No. 6, pp. 18-29, available at www.nxtbook.com/nxtbooks/naylor/NAPS0609/index.php#/18

U.S. Oil Output Exceeds ImportsA recent article in the St. Pioneer

Press discusses that the yearly U.S. crude oil output jumped 15.3 percent year-on-year in February, exceeding net imports of crude oil for the first time since 1996, government data shows.

This shift came 10 months earlier than had been projected by the Energy Information Administration, as domestic output hit a 21-year high of 7.177 million barrels a day. The increased flows are in part from shale-oil fields.

At the same time, U.S. crude oil imports dropped 15.1 percent, the lowest since March 1996.

Concrete pavement promoters have speculated for years that

light-colored concrete pavements would help to mitigate the UHI effect. The UHI effect is a well-documented phenomenon that results in urban areas being warmer than their rural surroundings; what has not been fi eld-proven, however, is the theory that light-colored pavements actually reduce the UHI effect.

New research by several universities is in fact showing that dark-colored pavements do more to mitigate the UHI effect than light-colored pavements.

The National Center of Excellence for Smart Innovations at Arizona State University (ASU) is studying the impact of pavement characteristics on air temperature. The hypothesis is that if pavement color has no impact on air temperature at, for example, 5 feet above the pavement, then pavement color has no impact on UHI.

Recently, Professor Kamil Kaloush provided a summary of the study’s initial fi ndings and stated, “Air temperatures at 3 and 5 feet above the [concrete and asphalt]

pavement surfaces are similar (< 1˚F difference). The research team believes that factors such as wind speed, rain, and humidity may have a more signifi cant role in air temperatures above pavements than pavement surface material

type.” The fi ndings from ASU’s research were recently presented at the 2013 Transportation Research Board Annual Meeting in Washington, D.C.

ASU’s fi ndings are paralleled by a similar study from the University of California at Davis, which concluded that air temperatures 1 foot or more above light-colored and dark-colored pavements were not signifi cantly different. In fact, refl ective pavements were shown to heat up adjacent buildings, actually increasing the UHI effect.

A recent study from the Jacob School of Engineering at

University of California - San Diego raises questions about relying on highly refl ective pavements to mitigate the urban heat island (UHI) effect. The UCSD study fi nds that during summer months such pavements can refl ect solar radiation into surrounding buildings and increase the need for energy to cool them.

For example, the study states that “Increasing pavement solar refl ectivity from 0.1 to 0.5 increased annual cooling loads up to 11 percent ... for a four story offi ce building ... in Phoenix, Ariz.” A synopsis of the study is available at:www.jacobsschool.ucsd.edu/news/news_releases/release.sfe?id=1281&

MAPA Updates

The figure below shows the number of Perpetual Pavement Awards per states or province.

The concept of Perpetual Pavement was introduced in 2001 by the Asphalt Pavement Alliance (APA) [visit the APA’s updated web site at www.AsphaltRoads.org]. From 2001 to today, the APA has presented 85 Perpetual Pavement awards. The awards recognize that

many well-built asphalt pavements have been in service for decades with only minor periodic surface

rehabilitation.

There are several advantages to building long-life pavements including low life-cycle cost, low user-delay impacts, and low environmental impacts by reducing the amount of materials needed over the life of the pavements.

The 2012 award winning project (USTH 61 from milepost 34 to 53) is an example of design and endorsement of long-life, perpetual asphalt pavement in Minnesota. The initial construction of USTH 61 began in 1969 and was paved by MN Valley (currently owned by Duininck Inc.). This 19.6 mile

segment had a 2 to 3 foot subcut and clean sand fill in certain areas to help correct for poor soils and swamp areas. This is critical for perpetual pavement design and also to create a durable pavement structure to withstand the freeze-thaw cycles that occur in Minnesota.

This segment of USTH 61 is a major rural highway through Minnesota that connects Iowa to Thunder Bay in Canada. Thanks to the progressive vision and partnering efforts of agency and industry representatives, this project has demonstrated outstanding design, construction, and performance value for 43 years of service to the traveling public of Minnesota.

Congratulations Mn/DOT!

Spotlight on Wayne H. Sandberg, P.E., Washington County Deputy Director/County EngineerAn interview by Jill Thomas, P.E., Associate Director, Minnesota Asphalt Pavement Association

“Be ethical. Be honest. Be fair. And you will be

happy.”

Words to live by, says Wayne Sandberg, the Washington County Deputy Director/County Engineer.

Wayne is a native of Forest Lake, Minnesota. When deciding on his future career, he followed his High School Guidance Counselor’s suggestions to pursue a degree in Civil Engineering. While attending the University of Minnesota, Institute of Technology, he also interned with the Minnesota Department of Transportation (Mn/DOT) Oakdale Traffic Engineering Office. When Wayne graduated in the early 1990’s, he began working as an Inspector for the City of St. Paul and gained valuable on-the-job experience on several transportation projects.

In 1997, Wayne began working for Alliant Engineering, Inc. based out of Minneapolis, MN. He was responsible for preliminary and final roadway design, as well as designing storm water retention ponds, plans for site developments, and closed circuit T.V. plans for the Mn/DOT Traffic Management Center. It was at this time that Wayne felt the desire to work in the public sector.

In 1999, Wayne became the

Washington County Transportation Engineer. He planned and administered the budget of the Traffic Division, supervised the Traffic Division staff, managed the installation and maintenance of all traffic control devices, and performed and evaluated traffic studies. He was also responsible for maintaining the County’s State Aid Needs Program.

Wayne was the Project Manager for the high-profile St. Croix Trail/County Road 18/Old TH 95 project near the St. Croix River. This project spanned 2.5 miles and had several accesses to local neighborhoods and businesses, however the 2-lane roadway had no turn lanes to allow for safe left turns. The newly constructed roadway now has 3 roundabouts and a bike trail on both sides of the street. This slowed traffic and improved access for the traveling public. Using asphalt pavement provided for ease of construction, maintaining traffic, utility cuts, and was the economical choice.

In 2011, Wayne became the Washington County Deputy Director/County Engineer.

He is responsible for the five-year capital improvement plan development that fluctuates between $75 and $150 Million dollars, and for determining the transportation services required to

accomplish the department goals.

The County has approximately 230,000 people and 271 miles of roadway centerline miles, 98 percent of which are asphalt pavement. Wayne relies on his staff of 56 and

their engineering consultants to accomplish their goals. He feels that they are dedicated and do a great job managing trust and dollars to bring value to the public.

When asked about challenges that he faces in his position, Wayne said it is stretching dollars to maintain infrastructure. He believes we need to invest in maintenance and that we are falling behind. The County estimates a deficiency of $5 Million in unmet needs per year. With increasing population and traveling needs, we need to have a healthy infrastructure to help grow the economy.

Spotlight on Wayne Sandberg, continued from page 6

The county takes public safety very seriously and is continually trying to improve safety. A major accolade for Washington County is that in 2009 they had zero fatal crashes on their roadway network - a significant accomplishment for a Twin Cities Metropolitan County.

Never one to rest on his laurels, Wayne is currently pursuing a Masters Degree in Public Administration at Hamline University. He will graduate in August of 2013.

Wayne and his wife Nichole have three children: Nicholas (12 years old), Erik (10 years old), and Kate (6 years old). In their spare time, they enjoy camping, traveling across the country by car, hunting, and fishing.

Best of luck Wayne, and thanks for building ‘em black!

SANDBERG AXIOMSWayne keeps track of good advice and the following are just a few of his “Sandberg Axioms”:

• In chaos there is hope.• Set the bar high, no one rises to low expectations.• Be ethical. Be honest. Be fair. • Try to see issues from others point of view. Always know there are two

(or more) sides to any story.• People will follow you as long as they can trust you are acting with their

interests in mind. Once you lose that trust, you have lost the ability to lead.

• Focus on winning the war. You can win small battles and still lose the war. Focus on winning the war.

• If you are willing to admit you made a mistake, people are ready and willing to forgive you. Don’t abuse this privilege.

• Giving someone credit is the easiest gift to give...it will return to you tenfold.

• Never, ever burn a bridge. You never know who your next boss is going to be.

• Listen more than you talk. Make sure that ratio is always on the listen side.

• Never, ever walk into a meeting and “wing it”. Prepare, plan, and anticipate.

• Good Engineers understand engineering. Great Engineers understand politics. The Best Engineers can comfortably work in both of these worlds.
