Fast Track Patching on I-64 in Williamsburg, Virginia
COMMAND Center™ was used to speed up the opening time of these I-64 pavement patches by accurately estimating the new concrete’s strength. Traffic was shut down overnight to allow construction crews to saw, remove shattered slabs, drill dowels, and place
Temperature Gradients for Mass Concrete on SH 45/Loop 1 in Austin, Texas
COMMAND Center™ was used to track mass concrete temperature gradients on SH 45/Loop 1 in Austin, Texas. Here, two sensors were used to determine the gradient between the core and surface of the concrete. Since both maturity data as well
Concrete Pavement Maturity Specifications Developed in Indonesia
The Indonesian Institute of Road Engineering (IRE), also known as Pusjatan, used COMMAND Center™ to develop a maturity specification for concrete pavements. The IRE will perform laboratory tests to establish a strength-maturity relationship for a concrete mix, and then verify the test
Curing Temperature Monitoring for Bridge Construction in Ames, Iowa
In order to allow construction throughout the fall and winter, contractors in Ames, Iowa are using COMMAND Center™ to verify the minimum specified temperatures (50°F) of in-place concrete. The COMMAND Center™ provides real-time feedback on the effectiveness of their curing
Maturity and Temperature Monitoring Research in Manchester, Iowa
In 2002, maturity concepts were applied to the construction of a two-lane rural road in Manchester, Iowa. Road-closure times were minimized using COMMAND Center™ so that the road could be opened to residential traffic as soon as possible. This paid
Freeze/Thaw Monitoring of Stabilized Base Course in Iowa
COMMAND Center™ sensors were embedded in an unpaved quarry road in Iowa to monitor freeze/thaw cycles throughout the winter and spring seasons. The road consisted of limestone screenings stabilized with fly ash and cement kiln dust. The sensors were compacted
