Perspectives on Portland-Limestone Cement

ACPA’ has published a “Perspectives” document stating the Association’s support for and encouragement for the acceptance and use of portland-limestone cement (PLC) or Type IL cement.

ACPA supports and encourages state DOTs and other agencies to allow its use as an option to help further improve concrete’s sustainable attributes.

PLC is an innovative cement that contains between 5% and 15% finely ground limestone, which can help reduce the carbon footprint of cement production by about 10% relative to ordinary portland cement (OPC).

Click here to download a copy of the document, which is included in ACPA’s ‘Perspectives’ library. ACPA Perspectives documents detail the Association’s formal positions and policies on timely issues of importance to the concrete pavement industry and the transportation-construction community. This is the 2nd new addition to the library this year.

Diamond Grinding Begins on Arizona Freeway

In Tempe, AZ, diamond grinding began last Friday on the Price Freeway Design Build Project, says Larry Scofield. 

The project, which was originally supposed to have rubberized asphalt placed, was change ordered to conventional diamond grinding. 

Approximately 500,000 sq yds of diamond grinding will be constructed by Diamond Surface, Inc.* of Minnesota. 

The existing rubberized asphalt has been previously removed leaving only a thin layer remaining to be removed along with the PCCP grinding, Larry says. This is the second diamond grinding project to occur this year on the Phoenix freeway. Grinding is accomplished during night closures.

Report Cites Superior Features of Concrete Pavements

A recent publication from the Australian Society for Concrete Pavements* says, “concrete pavements surpass asphalt pavements in all aspects.”

“Concrete Pavement Value: Economic, Operational and Community Benefits,” is a two-page “pavement note,” which explains that concrete pavements provide:

  • 25% lower construction costs vs. full-depth asphalt;
  • 50 to 60% lower maintenance costs over a 40-year life span; and
  • 50% fewer road closures and traffic disruptions.

The information was based on a metareview of 15 research reports, technical resources, and statistical information from well-known subject matter experts and technical organizations, including ACPA. Drawing on published resources, the pavement note presents facts clearly and concisely, and with supporting graphics and references.

The document says “(c)oncrete pavements are significantly lower in construction cost, maintenance cost and, consequently, whole of life cost. Additionally, they are smooth, skid resistant, more rapidly constructed, less labour-intensive, less equipment-intensive, more durable, and more
available in-service.” Click here to see the pavement note.

Organizations Unite to Support Infrastructure Investment

ACPA was one of 71 organizations* to sign a letter in support of the President’s stated goal of making increased federal infrastructure investment a top priority in the coming months.

The large and diverse ad hoc group represented transportation-construction associations, public officials, highway and roadway user groups, labor groups and many other stakeholders. In all, the groups represent thousands of companies and organizations, as well as millions of citizens.

For ACPA, this was another opportunity to maintain strong visibility and to continue efforts to inform and persuade elected federal officials to include transportation-construction in near-term economic rebuilding and to address long-term investment in highways, roads and other surface infrastructure.

“Time and again throughout the history of the United States, infrastructure has played an important role in jobs creation, economic growth, safety and security and the quality of life for all people,” says Leif Wathne.

TRIP Report Underscore Importance of Highways and Roads

The Road Information Program (TRIP) recently released its latest reports on “America’s Surface Transportation System and Federal Funding.”

The reports provide national perspectives and state-by-state information about the critical needs and value of the nation’s highways and roads. TRIP makes the reports available to stakeholders further supports the dissemination of the information with media work at both the national and state levels.

ACPA is pleased to support the effort with this story and other communications efforts. Here are just a few of the very important and  timely points from a national perspective:

  • Investments in the surface transportation system will boost the nation’s economy in the short-term by creating jobs. In the long-term, investments will enhance economic competitiveness, stimulate sustained job growth, improve access and mobility, improve traffic safety, reduce travel delays and improve road and bridge conditions.
  • Roads and highways are the backbone of our economy, allowing U.S. motorists to travel 3.2 trillion miles annually. They are vital to moving a significant portion of the $16.8 trillion worth of commodities shipped within the country each year. But, conditions on the system are deteriorating, as the need for transportation improvements far outpaces the amount of state and federal funding available.
  • The design, construction and maintenance of transportation infrastructure in the U.S. supports approximately 4 million full-time jobs across all sectors of the economy.
  • Approximately 62.9 million full-time jobs in in key industries like tourism, retail sales, agriculture and manufacturing are completely dependent on the nation’s transportation network.
