Soft aggregate, sound solution

FF-HwySnd1-150

This summer a four-mile stretch of the Dulles Connector Road became the first phase of a larger project in northern Virginia to include ground-mounted sound walls containing SoftSound, a sound absorptive technology. Approximately 277,000 square feet of precast concrete sound wall will be placed on the west side of the roadway between Chain Bridge Road/Route 123 and Interstate 66. The sound walls will mitigate noise from Dulles Connector Road traffic and the new Dulles Metrorail Silver Line extension, which has been constructed at-grade in the median and on elevated rail flyovers along the roadway.

Penetrating lubricant

EP-Berkebile-150

Protection First Class (PFC) penetrating lubricant and rust inhibitor represents company’s entry into a new category of environmentally responsible formulations, as indicated in a 99 percent pure cosmetic-grade lanolin composition. Traditional penetrating lubricants use solvents to lower the viscosity of the oils they contain, enabling them to flow more easily or to be dispensed as a spray. The solvents break down some of the essential properties of the oils they mix with and, after quickly evaporating, leave a dry, varnish-like residue that can collect dirt and may actually increase surface friction—thus impeding mechanical action.
