Grand Junction Regional Airport (KGJT) concrete apron passes tests

It took two tries, but work on the east apron at the Grand Junction Regional Airport is now complete and should last for 20 years.

The concrete was replaced for the second time in the past year after the first attempt failed a long-term strength test by the Federal Aviation Administration.

The work wrapped up Nov. 6 and the concrete has passed all tests — including the long-term strength test.

The apron is the area where aircraft park for boarding, deplaning and fueling.

Strength tests are administered by sending a sample of concrete to a testing facility. After 28 days, weight is applied to the concrete until it cracks.

Contractor Interstate Highway Construction took on the cost for the second replacement. The airport had withheld $1.6 million of the $4.3 million project because of the failed test. Now that the work is complete, the airport will start paying the remaining balance, according to airport Planning and Development Manager Eric Trinklein.

The replacement work was expected to take until late November and wrapped up early, Trinklein said.

"We thought it would take until Thanksgiving, and they're completely done and out of there," he said.

The east apron, located on the east side of the terminal, is two acres in size and contains 10,700 square yards of concrete that is 16 inches thick.

The airport also recently wrapped up work on a taxiway repavement that was done over two weekends. The project removed and replaced surface pavement from Taxiway A. The work was finished Nov. 3.

A taxiway is where aircraft wait to take off.

Trinklein said that while the pavement was replaced, planes would pull onto the runway and back up to wait their turn for clearance.

The airport received a $1.5 million grant from the Federal Aviation Administration for the project.
