“Transportation Moves America’s Economy” is the theme of the 2011 TCC Legislative Fly-In, based at Mandarin Oriental Hotel in Washington, D.C. The event will kick off May 24 with a 2 p.m. Legislative Briefing, followed by a 6 p.m. Capitol Hill reception. A breakfast session on May 25 will lead into participants’ meetings with their representatives on Capitol Hill. A group of TCC sponsors have planned a separate “Rally for Roads” on the National Mall, scheduled in between the second day’s morning and afternoon sessions.

Using 2009 statistics, USGS has produced its yearly Top 100 list of crushed stone producers in the nation, and Birmingham, Ala.-based Vulcan Materials Co. retaining the top spot. Rock Products published an enhancement of the list in its May issue, which included contact information for each major producer. USGS obtains its data from production and sales reports provided by the crushed stone operations. When an operation does not report any data to the USGS, their total production is estimated by using employment data provided by the Mine Safety and Health Administration (MSHA).

Regional marketer FlyAshDirect stands to greatly expand its Class F fly ash delivery footprint following installation of railcar- and pneumatic tanker-loading equipment at American Electric Power’s John E. Amos Generating Station near Charleston, W.V. It has secured exclusive rights to market ash from the CSX rail-served, three-unit station—the fourth AEP operation in the FlyAshDirect portfolio. More than half of the 2,900MW facility’s approximately 1 million tons/year of ash is concrete-grade, with a carbon content below 2 percent.

A change in ASTM C90-prescribed web configuration for concrete block has the potential to lower products’ material use and transportation costs; increase masons’ productivity through lighter units, while reducing fatigue and injury associated with heavier block handling; ease rebar congestion and grout placement in reinforced wall assemblies; and, boost R-values by a factor of 3 to 4, owing to improved thermal properties.
Source: National Concrete Masonry Association NCMA is soliciting feedback on a beta version of a draft plant certification program, available for review here. A voluntary compliance option for concrete masonry and hardscape unit producers, the certification program outlines the minimum quality control process requirements for plants serving markets where customers or specifiers seek documentation beyond the QA/QC embodied in ASTM…
