What is Asphalt Pavement? FAQs answered by a Baltimore Asphalt Contractor

Thursday, February 21st, 2013

At Reliable Contracting, we offer everything from the installation of hot and cold-mix asphalt to asphalt patching, large parking lotmilling, seal coating, and crack filling. But what does this all mean? For that matter, what is asphalt pavement?

You undoubtedly use asphalt pavement each and every day. Asphalt is used for everything from driveways to highways to parking lots and everything in between. So what goes into making this versatile product?

What is Asphalt Pavement?

Asphalt pavement is made up of several ingredients, including aggregate (stone), sand, and additives – which makes up about 90-95% of the pavement – and liquid petroleum (liquid asphalt), which binds the aggregate, additives, and sand together.

Asphalt Fun Fact: Did you know that asphalt is the most recycled product in the United States? Approximately 80% of all asphalt pavement is recycled.

How is Asphalt made?

  1. Predose: First, the aggregate components are weighed using a belt weighing instrument, while being transferred to the next step in the process.
  2. Drying: A rotary drying drum is used to dry the components at roughly 300 degrees.
  3. Reweighing: After drying, the aggregate is weighed a second time.
  4. Sifting & Storage: The dried components are then sifted and stored in silos.
  5. Mixing: The aggregate is transferred to the mixer and the liquid asphalt binder is added according to a measured rate of flow.
  6. Storage: Once the asphalt pavement is mixed, it is stored in a heated silo. If the asphalt mix cools it cannot be compacted.

Winter Asphalt Paving: Is it too Cold to pave in the Baltimore Area?

Friday, February 8th, 2013

Reliable_Feb4

It is winter. That means it is impossible to pave, right? Wrong! We have found that many of our clients have the same common misconception that asphalt paving cannot happen in cold weather. While cold weather paving is more difficult and has many more challenges, it is possible.

Cold Weather Paving Challenges

  1. Transportation: The main challenge is transportation: getting asphalt to the job site and compacting it before it cools. This requires a well-organized and highly-skilled asphalt contractor.
  2. Manpower: Cold weather paving requires a lot of man power to get the job done right before the asphalt cools. This is why you should use qualified asphalt companies.
  3. Asphalt Plants: Most asphalt plants stop production in mid-December. Reliable contracting company keeps there plant running most of the winter.

The Solution: Trust Reliable Contracting!

Reliable Contracting Company is a full-service commercial and residential asphalt paving contractor. We offer a wide range of services, from production and installation of hot and cold-mix asphalt to asphalt patching, milling, and crack filling. But that’s not all. We also offer parking lot striping, signage, parking bumpers and speed bumps.

Oh yea, and did we mention that Reliable Contracting operates three hot-mix asphalt plants in Anne Arundel County? This affords us unequalled reach for commercial asphalt projects in the Baltimore, Annapolis and Washington D.C. metropolitan areas.

Admixtures Change PCC Performance :: Concrete Contractor in Maryland

Thursday, June 28th, 2012

The most widely used structural material for transportation infrastructure and pavements in Portland cement concrete, or PCC. And in order to achieve a PCC mixture that is workable, durable, and of high quality, mineral and chemical admixtures must be applied.

All about Admixtures

  • Chemical Admixtures: The most common chemical admixtures are air-entraining agents, water reducers, superplastics, retarders, and accelerators. All of these admixtures can affect PCC in several ways, including: managing its rate of early hydration and regulating its fluid properties.
  • Mineral Admixtures: Common mineral admixtures include fly ash, silicia fume, and microsilicia. These admixtures are added to concrete to enhance its workability; to improve resistance of concrete to thermal cracking, alkali-aggregate expansion, and sulfate attack; and to enable a reduction in cement content or water.

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.

If you have any questions about the Troubleshooting Pervious Concrete or if you have a construction project that you need completed right the first time, please contact Reliable Contracting by calling 410-987-0313 or visit our website.

Green Infrastructure to Manage Stormwater :: Reliable Contracting

Thursday, May 17th, 2012

The Environmental Protection Agency (EPA) and the city of Philadelphia, Pennsylvania recently signed a $2 billion agreement allowing the city to use green infrastructure – including porous pavements, rain gardens, grassy swales, and more – to better manage stormwater flows. These green alternatives will supplement traditional pipes and concrete infrastructures.

This is all part of the city’s “Green City, Clean Waters” plan, which is designed to protect and enhance urban watersheds by managing stormwater with greener techniques.

How Green Infrastructures Work

These methods intercept rain water at the source, retaining it and allowing it to flow into the ground. This then allows the soil and plants to recycle the water back into the atmosphere, preventing it from becoming stormwater runoff.

The EPA’s Role in this 25 Year Partnership

  • EPA will provide technical assistance to Philadelphia. This includes identifying and promoting higher-performing green infrastructure designs.
  • The EPA will join forces with the city of Philadelphia in several demonstration projects, such as greening a school’s gardens and revitalizing a low-income neighborhood with green designs.
  • The EPA will provide technical assistance and will help monitor the effectiveness and benefits of this program.

“Where other cities are challenged by very expensive commitments for tunnels, tanks, and other gray infrastructure, we have worked with the state and the EPA to take this greener, more fiscally prudent approach that will realize multiple benefits,” said Philadelphia Mayor Michael Nutter (D).

If you have any questions about the EPA’s Agreement with the City of Philadelphia or if you have a construction project that you need completed right the first time, please contact Reliable Contracting by calling 410-987-0313 or visit our website.

Construction Industry News: EPA Trying to Pass New Stormwater Rule

Friday, May 11th, 2012

The Environmental Protection Agency recently created a general permit for stormwater runoff from construction sites. The new permit – titled the National Pollutant Discharge Elimination System (NPDES)  - went into effect on February 16, 2012.

For more information, refer to the following: FR Notice (PDF) (8 pp, 180K).

The 2012 CGP replaced the 2008 CGP, which expired on February 15, 2012. This new permit will provide coverage for eligible new and existing construction projects for a period of five years.

Features of the 2012 Construction General Permit (CGP)

• The 2012 CGP includes a number of modifications to the 2008 CGP, many of which are necessary to implement the new Effluent Limitations Guidelines and New Source Performance Standards for Construction and Development point sources, known as the “C&D rule.”

• Does not include turbidity limits.

For background on the EPA’s original rule and related legal wrangling, see EPA to Reconsider Key Aspect of Construction Stormwater Rule, by attorneys Meline MacCurdy and Russell Prugh of Marten Law (September 30, 2010).

The Types of Asphalt Explained

Friday, February 17th, 2012

Last week, we gave you a quick overview of the History of Asphalt. This week, we are going to take a look at the many different types of asphalt pavement currently available. You may be surprised at how versatile this paving material really is. The different varieties of asphalt pavement include:

Perpetual Pavement: Take the smoothness and safety advantages of traditional asphalt and throw in an advanced, multi-layer paving design process. When you couple that with routine asphalt maintenance, you get a pavement material designed to last! The advantages of perpetual pavement include:

• Perpetual Pavements can be maintained easily

• Surface restoration is extremely cost effective

• Reconstruction can be performed without removing the old road structure

Porous Asphalt: This type of asphalt is the perfect way to manage storm water and eliminate standing water, which can wreak havoc on your asphalt surface. Used primarily for parking lots, porous asphalt allows water to drain through the pavement into a stone recharge bed and then into the soil below. The advantages of porous asphalt include:

•Porous asphalt can provide cost-effective, attractive pavements

• Experiences few, if any, cracking or potholes

• A life span of more than twenty years

• Provide storm-water management systems that promote infiltration, improve water quality, and many times eliminate the need for a detention basin

Quiet Pavement: Today’s busy world is noisy enough. Quiet pavement is designed to eliminate at least some of that noise. The advantages of quiet pavement include:

• Noise experienced both inside and outside homes and businesses can be significantly reduced

• Research shows that resurfacing a noisy road with stone-matrix asphalt (SMA) or open-graded friction course (OGFC) mix will reduce highway noise by 3 to 5 dB(A) or more

Warm-Mix Asphalt: This is the generic name of the technology that allows manufacturers of hot-mix asphalt to lower the temperatures at which the material is mixed and placed on the road. The advantages of warm-mix asphalt include:

• Reductions of 50 to 100 degrees Fahrenheit have been documented

• Improved safety for asphalt workers

• Decreased production of greenhouse gases

• Decreased fuel consumption

• Better compaction of pavements

• Extended paving seasons

• Potential to be able to recycle at higher rates

Hopefully, now you know more about asphalt than you did before!

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
