Association & Industry News
The RMC Research & Education Foundation has released its latest pervious concrete research report, Predictive Model for Void Content and Strength of Pervious Concrete Pavements Installed in the Field. Performed by researchers at Washington State University, the project includes the development of a model that may be used to predict the void content and compressive strength of pervious concrete field installations based on mixture composition and the compaction level. Installers can use a database of their mixture composition, roller screed weight, revolutions per minute, void content and strength of cores from past projects to recalibrate the developed model. The calibrated model can then forecast the required compaction to produce the target void content and strength. The project included both laboratory and field testing and looked at several variables, including roller screed weight and the number of passes.

Earlier this week, NRMCA Safety, Environmental and Operations staff met with members of the Office of Information and Regulatory Affairs (OIRA) within the White House Office of Management and Budget (OMB), members from the U.S. Department of Labor (DOL) and Small Business Administration (SBA) to discuss the potential of an emergency temporary standard (ETS) DOL is promulgating. The potential ETS would require businesses take certain steps to keep workers safe from COVID-19 transmission, an escalation of DOL’s current COVID-19 focus from voluntary guidance to a specific mandate. NRMCA relayed to OIRA, DOL and SBA staff that such a standard is not only not necessary, but that the current COVID-19 cases, deaths and vaccination data don’t support mandating new measures. NRMCA outlined the specifics of the ready mixed concrete industry, its workforce, when, where and how employees work, as well as how the industry has kept its workforce safe since the inception of the pandemic. NRMCA also conveyed the work it has done with industry partners on workplace safety and what an ETS should encompass if finalized. OIRA will likely finalize its assessment of the ETS in the next couple of weeks at which time any potential ETS language could be released. After OIRA’s review, the rule’s finalization could follow. NRMCA will continue to monitor movement on the potential ETS from OIRA and DOL. For more information, contact Gary Mullings at gmullings@nrmca.org or Kevin Walgenbach at kwalgenbach@nrmca.org.

As Congressional committees prepare to consider surface reauthorization legislation in both the House and Senate, NRMCA joined letters penned by the National Stone, Sand & Gravel Association and the Portland Cement Association to urge Congress to reject efforts to expand Buy America restrictions on federal procurement. Last year, during the consideration of the INVEST Act by the House Transportation and Infrastructure Committee, an amendment was adopted to include “construction materials” in the Buy America provisions governing Federal Highway Administration procurement. This addition could extend Buy America requirements to aggregates and cement, and NRMCA and its partners are strongly advocating against these policies. Similar efforts to include construction materials in Buy America policies are being considered by the Senate. NRMCA will continue to join our allies in opposing these harmful policies that will make construction more expensive and reduce the buying power of federal infrastructure dollars. You can read the letters here and here. For more information, contact Andrew Tyrrell at atyrrell@nrmca.org. NRMCA joined the Owner-Operator Independent Drivers Association and a host of other industry groups in advocating for Congress to reject proposals to increase the minimum insurance for heavy trucks. Last year, the surface reauthorization package passed by the House of Representatives included a provision to raise the minimum insurance level from $750,000 to $2 million per truck. The coalition has met with dozens of Congressional offices, stressing the potential negative impacts on small trucking companies and pointing to federal safety data indicating that current levels cover the damages in more than 99% of crashes. In addition to meeting with dozens of Congressional offices, NRMCA joined the coalition in sending letters to the Indiana and Illinois delegations as well as members of the bipartisan Problem Solvers Caucus and the Democratic Blue Dogs Coalition. NRMCA members also advocated on this issue during the Cement and Concrete Fly-In in April. For more information, contact Andrew Tyrrell at atyrrell@nrmca.org.
