Sizing up nano-scale materials

For the third year in a row, we visit a pavement project VCNA Prairie Material helped convert from all asphalt to partial (base slab) or 100-percent roller compacted concrete. More than a routine switch, the Maryhill Cemetery maintenance shop (pages 28-31) marks the commercial debut of RCC Surface Pro, a silica agent emanating from the field of nanotechnology, where particles are measured in billionths of a meter.

FHWA, AASHTO gauge real-time concrete pavement quality

Crews deploy real-time pavement smoothness technology on Texas’ DFW Connector, a design-build project of Northgate Constructors, Kiewit-Zachry joint venture.

In an effort to reduce costs, increase pavement quality, and minimize travel delays caused by road construction, the Federal Highway Administration, American Association of State Highway and Transportation Officials (AASHTO), and Transportation Research Board will help agencies implement a tool that allows contractors to identify concrete pavement surface irregularities during construction.
