Concrete Industry Promotion Debunked
Representatives of the concrete and cement industry of Colorado are distributing and promoting the use of a life cycle cost analysis (LCCA) software developed by the National Ready Mixed Concrete Association (NRMCA). The software, entitled The Concrete Pavement Analyst (CPA) is being promoted as a “.. powerful tool to make pavement design comparisons …” The Asphalt Institute has completed an analysis of the software and has concluded that (no shock here) the CPA software “.. has unreasonable biases to skew results in favor of concrete.” Asphalt Institute – Concrete Pavement Analyst (CPA) – Setting the Record Straight and the Asphalt Alliance - LCCAExpress.

Question: Does Asphalt Shrink?? Answer: No!! Asphalt Does not shrink. Occasionally engineers reference to asphalt “shrinking” as the cause of premature cracking. Asphalt does not shrink. Here are two reference documents Edge Cracking – Final Report and Edge Cracking –Technical Brief that address this issue.

Green Light Given for Warm Mix Asphalt in Ohio – The Ohio DOT has removed the restriction on the use of warm mix asphalt (WMA) in its heavy traffic surface courses. With this change, foamed WMA, per item 402.09 can now be used in all traffic classes and all pavement courses. (read more)

Warm Mix Asphalt – Use and Implementation Update: Larimer County will be partnering with Lafarge West Inc. in a trial use of warm mix asphalt (WMA). The paving will include WMA (and top mat RAP) and be on County Rd. 17 on the south end of Loveland. It's about 3/4 mile section of arterial road and the scope of the paving is a patch and fabric job with a 5" overlay.

Detecting Recycled Asphalt Shingles (RAS) in Hot Mix Asphalt: Questions have been raised on how an owner/agency can test to determine the presence of recycled asphalt shingles in HMA. The simplest thing to do is A) conduct an AC Content Determination Test using an ignition oven test and look for fibers (should be able to see the fiberglass ones) or B) do a solvent based extraction test and look for fibers (fiberglass and organic ones). Either of these approaches should give a yes or no indication of the presence of shingles. An estimated range of shingle content used can be estimated based on the fiber content.

Asphalt Industry Releases New Life Cycle Cost Software
The Asphalt Pavement Alliance (APA) has developed new software for life-cycle cost analysis (LCCA) of pavements. The new software, called LCCAExpress, uses the principles recommended by the FHWA to compare the economics of alternative designs for a given road project. LCCAExpress is a simplified version of the APA’s original LCCA software. Geared to less-complex projects, it’s quick, easy to use, and unbiased. “The new software is designed for counties, cities and consultants. It is a very robust software and not daunting for the user,” said Jill Thomas of the Minnesota Asphalt Pavement Association, co-chair of the APA’s Economics Team.

LEED and Green Construction - The U.S. Green Building Council’s LEED (Leadership in Energy and Environmental Design) Green Building Rating System serves as a scorecard for the design, construction, and operation of green buildings. It was designed to encourage the adoption of sustainable building and development practices. Sustainable development tries to balance the needs of people, nature, and the economy. Pavement type selection (concrete vs. asphalt), on its own, directly contributes to only a few LEED credits. Credits can be earned in these ways: (read more)

Thin Lift Overlays for Pavement Preservation – Agencies are being forced to stretch road improvement budgets and to maximize the number of roadways being repaired and improved. Thin lift overlays are a tool in the box for pavement preservation. Best practices for material selection need to be followed when using thin lift overlays. In the Pueblo area, a new thin lift gradation (SX Modified) has been developed for 1-1/2” or less paving lifts with a 3/8” nominal maximum aggregate size (read more).

Quality Requirements for Recycled Asphalt Shingles (RAS) – The “Best Practices” are being developed for the use of recycled asphalt shingles (RAS). The Nebraska DOT RAS specification addresses maximum amount of RAS, not allowing any deleterious material, sizing of material, and a certification of product. CAPA continues to partner with the Roofs to Roads project in Colorado.

Maintenance of Asphalt Pavement – Cost Comparison Worksheet, August, 2009 This document (developed by the Minnesota Asphalt Pavement Association) includes a Worksheet that can be used to develop a comparative analysis of strategies and options. The worksheet can be used to develop a Cost/Service Life/Sq.Yd. The primary variable will be the input value for years of service for each strategy.

Having Trouble convincing Elected Officials of the Need for Road Funding?
The American Public Works Association (APWA) has developed an excellent publication entitled “The Hole Story – Facts and Fallacies of Potholes” that helps explains the challenges of deferred maintenance. Also, CAPA Executive Director Tom Peterson has developed a White Paper on the subject entitled “Fix it Now or Fix It Later – The Public Works Dilemma of Deferring Road Improvements.” A limited number of copies of the APWA brochure are available from the CAPA office office@co-asphalt.com

Resources Tool Kits – CAPA has developed a number of informational packets (Resource Tool Kits). These Resource Tool Kits include the following; enviro

Hot Mix Asphalt Production Facilities (environmental issues regarding HMA facilities)
Benefit and Use of Recycled Asphalt Pavement (specifications, QC plans, stockpile management requirements, research)
Environmental Sustainability of Asphalt Pavements (porous asphalt/water quality, perpetual pavements, clean air/cool cities, energy and conservation).
The Need for Road Funding (the importance of road maintenance, the problem of deferring roadway maintenance, etc.).

A variety of documents (ie. reports, brochures, literature, etc.) on each subject have been compiled in a folder for each subject. To obtain a complimentary copy of the folder, contact Tom Peterson at tompeterson@co-asphalt.com or at (303) 741-6150.
