Sustainability, Warm-Mix Asphalt & Reliable Contracting in Baltimore

Tuesday, May 14th, 2013

Warm-Mix-AsphaltWhen was the last time you were driving down the highway and thought to yourself, “How does this asphalt affect the environment?” Odds are that thought has never really crossed your mind. But if it has, or if we now have you thinking, you are in luck. We have the answer!

Asphalt is actually one of the most environmentally friendly building materials around.

  1. Recycling: Asphalt is actually the most recycled material in the United States. When an old asphalt pavement is removed, 99% of the time it is recycled or reused.
  2. Storm Water Runoff: Porous asphalt helps manage storm water runoff, improving water quality.
  3. Fuel Efficiency: Because asphalt is so smooth, tires rolling across it encounter less resistance than on other types of pavements. The result: improved fuel economy!
  4. Greenhouse Gases: The amount of energy used to produce and the amount of greenhouse gasses produced during asphalt production are much smaller than alternate paving materials.
  5. Warm-Mix Asphalt: Because warm-mix asphalt is produced and placed at a lower temperature, it saves energy and reduces the production of harmful greenhouse gases, while still meeting rigorous industry criteria for installation and durability.

Reliable Contracting in Baltimore: Warm-Mix Asphalt Production

At Reliable Contracting, we have always prided ourselves on being an innovator in the use of recycled materials, including burning recycled oil for fuel, producing glassphalt paving mixes, and recycling asphalt and concrete for base materials. But that is just the beginning of our environmentally friendly construction practices. We have recently expanded our capabilities ot include the production of warm-mix asphalt.

Excavation & Grading: The Initial Two Step in any New Asphalt Construction

Thursday, July 12th, 2012

New asphalt cannot be laid on top of damaged asphalt. Before road, highway, or parking lot construction can take place, the existing asphalt structure must be excavated and then graded. These steps are crucial in the overall construction process.

  • Excavation: The existing asphalt must be removed. Excavation is the process of preparing the prospective location of the driveway for the asphalt that will eventually be laid.
  • Grading: Now the area must be shaped, creating the proper pitch in the underlying material so that water drains properly once the asphalt is in place.

Pervious Concrete: Developing the Right Concrete Mix

Monday, June 18th, 2012

Pervious concrete is designed to easily drain water. This is accomplished through a serious of void spaces, known as the porosity, which are interconnected and rapidly permeable to water movement. As you can imagine, this creates a unique set of challenges for the concrete producer.

Developing a pervious concrete mix that is easily placed, performs well, and is durable is not easy. It is a balancing act, requiring the concrete producer to develop mix designs for each of his aggregates. It also requires producers to identify the warning signs of pervious concrete problems, specifically problems related to the following:

  • Water content
  • Mixture proportions
  • Admixture dosing

While some of these issues can be remedied by changing construction practices, most problems require changes from the concrete producer.

Producing Pervious Concrete

  • Permeability: The primary considerations when determining proper mix design for pervious concrete are: strength for loading; freeze/thaw resistance; durability against winter maintenance (plowing and deicers); and porosity to produce the desired permeability.
  • Workability: While pervious concrete requires proper void content, it still needs to be smooth and durable. This is achieved through proper mix proportions, primarily controlled by aggregate angularity and gradation; cementitious volume; sand or fiber content; water-cementitious materials ratio (w/cm); admixtures; and environmental factors (mixing time, water temperature, and mixer/truck moisture state).
  • Mix Constituents: The largest volume of material in pervious concrete is aggregate. Because of this, aggregate selection has the largest influence on unit weight. The use of good quality, clean, well-graded crushed aggregate results in pervious concrete pavement with improved structural properties, reduced raveling, and improved permeability.
  • Admixtures: There are numerous admixtures used in pervious concrete, including: air entraining; internal curing; hydration stabilizing; viscosity modifying; and water reducing.

The History of Asphalt

Thursday, February 9th, 2012

Often time in life, we take the inventions and innovations around us for granted. For instance, when is the last time you really sat there and thought about how a light bulb works, or where you would be if it were never invented? What about your computer? Most of us cannot function nowadays without our computer, laptop, or smartphone. And then there are those innovations that make our lives easier that we rarely ever notice, like asphalt; it’s everywhere from shingles and sidewalks to driveways, roads, and more. In fact, over 750 million tons of asphalt is poured and rolled every year in the USA, alone.

But where did asphalt come from?

Asphalt Facts

• Asphalt occurs naturally in asphalt lakes and rock asphalt.

• Asphalts first recorded use was in Babylon in 625 B.C. in the formation of roads.

• The ancient Greeks and Romans used asphalt to seal their baths, reservoirs, and aqueducts. In fact, the word asphalt comes from the Greek word “asphaltos”, meaning “secure.”  The Romans later changed the word to “asphaltus.”

• Sir Walter Raleigh wrote about using natural asphalt to re-caulk his ships in 1595.

• Then, in the mid 1800’s, John Loudon McAdam used hot tar to bond broken stones together.

• In the late 1860s, “asphalt” came to America!

• The first bituminous mixtures were used for sidewalks, crosswalks, and roads.

•  Then in 1870, Edmund J. DeSmedt laid the first true asphalt pavement in America, a sand mix in front of the City Hall in Newark, New Jersey.

Since then time, asphalt has really taken off.

Benefits of Warm-Mix Asphalt

Friday, February 3rd, 2012

The National Asphalt Pavement Association (NAPA) first introduced warm-mix asphalt (WMA) to the United States in 2002 after WMA grew in popularity in Europe. This new technology instantly spurred interest for government agencies, researchers, contractors, and especially hot-mix asphalt producers.

Warm-mix asphalt allows producers of asphalt pavement material to lower the temperatures – by as much as 100 degrees Fahrenheit – at which the material is mixed and placed on the road.

Benefits of Warm-Mix Asphalt

•Lowers fuel consumption

•Drastically decreases the production of greenhouse gases

• Reduces the production of emissions

• Improves working conditions for asphalt pavers
