Sawyer County Airport (HYR) – Hayward
Becher Hoppe was selected for various projects and the Sawyer County Airport in Hayward Wisconsin. One of these projects consisted of evaluating the pavement infrastructure and developing a plan for pavement rehabilitation to extend the pavement service life. The design and survey team use a drone equipped with a real time kinematic (RTK) GPS and a photo sensor to collect hundreds of aerial images. The images were processed to produce an orthorectified mosaic image of the entire airport pavement surface. The orthoimage was evaluated to identify joints and pavement distresses and develop a rehabilitation plan. Project cost estimates were prepared from quantity data taken from the orthoimage.
