Wagin airstrip gets a facelift

SUB BASE: The cement stabilization machine mixes the cement and gravel for the sub base, overseen by one of the contractors. 

WORK has started on the $580,000 upgrade to the Wagin Airport, which will see the sealing of the East West runway.

Shire chief executive Len Calneggia said there had been a lot of work done in the past week, with all of the sub base having been completed and the top base having been transported to site.

“The shire is trying to get this done as soon as possible,” Mr Calneggia said.

The works are expected to be completed by April 25.

Due to the location of the airstrip next to a salt lake, the sub base stabilization needs to be spot on to ensure that the bitumen does not lift off.

The sub base is prepared by mixing cement into the gravel with a cement stabilization machine, with some areas vulnerable to water having quick lime added as well.

Then 150 millimetres of gravel is laid down, with 150 millimetres of cement on top of that.

The surface is finished off with three coats of bitumen, the final one containing sand to create a smooth surface.

“With the infrastructure already in place, we want to ensure that Wagin has an all-weather strip,” Mr Calneggia said.

Mr Calneggia said he considered the project a high priority.

The upgrade has been funded through the Regional Airports Development Scheme, which contributed $411,000 in grant money towards the project.
