Upcoming Concrete Pavement Inspector Certification

The upcoming Concrete Pavement Inspector Certification will be held on June 09 as a virtual training. If you are registered you should have received an email letting you that the training has been moved online. 

The exam portion of the certification will be held in person on June 12. Registrants should contact Sarah Sanders (ssanders@pavement.com) to schedule their exam.

Registration for the certification is required and there are still spaces open for the June training/exam. Click here to register!

ACPA and CP Tech Center Upcoming Webinars

 

ADA Webinar Series

Register for our ADA Webinar Series by clicking here – it’s a 2-part webinar on May 12 and 19 @ 11 am MDT.  Engineers are faced with ongoing planning, design, and construction challenges when it comes to following ADA guidelines. Whether you are with a DOT, county, city, consultant, or contractor there will be lots to learn on implementing your ADA program.

This ADA Webinar Series is offering Professional Development Hours (PDH’s).  Attendees will:

  • Learn the requirements and importance of an ADA Transition Plan
  • Learn the design and construction requirements detailed in PROWAG 2011
  • See how these guidelines are being implemented in Wisconsin and Missouri

Sign up is required, and we have an improved two-step process to ensure proper processing for PDH’s.  Please click here to register.

Sustainability in Concrete Pavements

The role of concrete in connecting us to our daily lives and keeping our economy moving

The roadways and airstrips connecting our nation are integral to our society and daily lives. We expect smooth drives and safe landings, yet we rarely stop to think about the foundation of those expectations: the best material that can be used to surface roads, runways and other infrastructure.

Concrete pavements are a staple of our infrastructure – a durable, economical and sustainable solution for our roadways, airstrips, military bases, parking lots and sidewalks. Additionally, concrete pavements offer many safety benefits to drivers.

Durability
Simply put, concrete pavements have the longest lifespan of any paving material. It can withstand the freezing winters of the upper Midwest to the scorching summers of the Southwest, with an average service life of 30 to 50 years.

Sustainability
Concrete pavements consume minimal materials, energy and other resources throughout its lifespan, giving it a lower overall energy footprint, and offers better fuel efficiency for drivers. Concrete pavements have a lower energy footprint associated with production, delivery and maintenance than asphalt pavement.

  • Concrete’s lighter color reduces the amount of power necessary for illumination and mitigates the urban heat island effect.
  • Tires driving over smoother roads get better mileage per tank of gas; the overall better condition of concrete pavement compared to asphalt gives drivers better roads and better mileage.
  • Concrete can be 100% recycled at the end of its service life, making it a renewable pavement option.

Economical
Concrete pavements require minimal materials and energy for initial construction and do not require repeated resurfacing, spot repairs or patching. Compared to other road surfacing materials which require constant maintenance, concrete is cheaper to use at the outset and less expensive throughout its lifespan because it does not require extensive upkeep.

  • It was estimated that using life-cycle cost analysis for pavements alone can save an average $91 million for every $1 billion spent, or 9.1 %, when comparing equivalent concrete and asphalt pavement alternatives.
  • The use of concrete pavement is less disruptive to traffic – the construction of concrete pavements does not require lengthy lane closures and roads can be reopened in as short as six hours.
  • Concrete pavement can dramatically increase the life of transportation systems, cutting the amount of yearly repairs and spreading them out over longer time periods.

Reducing Emissions in Concrete Production

Concrete is the universal building material – from pavements and bridges to buildings, water storage tanks, counter tops, and everything in between.  The manufacture and construction of building materials produces emissions, and concrete has recently been singled out.  The reality is that emissions from cement production make up less than 1.5% of the national total, and the concrete industry in the US has been actively working to reduce emissions for many years.

Note:  Cement emissions are included within the Industry category.

Major cement producers with plants in Colorado have reduced net emissions per ton of cementitious product by 21-25% since 1990 and are utilizing renewable energy sources for up to 26% of their power consumption.  In partnership with owners and specifiers, the concrete industry in Colorado is focused on providing an even higher quality product while reducing the impact on our environment.

Join our efforts in reducing emissions by following these recommendations:

Innovations

  • Use portland limestone cement (PLC), which incorporates up to 15% finely ground limestone during production, to reduce clinker factor and corresponding carbon footprint.
  • Optimize aggregate gradations to construct a more durable pavement with a reduced cement content and corresponding lower emissions impact.
  • Introduce recycled CO2 into new concrete through CO2

Reducing & Recycling

  • Eliminate minimum cement content and include performance specifications instead of prescriptive to specify properties related to increased durability.
  • Replace 20% or more of the cement with fly ash to improve concrete quality and beneficially dispose of a waste product.
  • Incorporate recycled concrete aggregate (RCA) into new concrete pavement to reduce mining, processing and transportation.

Longevity

  • Build long lasting pavements to extend the time between recycling pavement and reduce construction emissions caused by frequent rehabilitation cycles.
  • Diamond grind the surface of concrete pavement to restore smoothness and extend life without the need for additional raw materials.
