Notwithstanding, broken asphalt occurs in a somewhat haphazard and random fashion, which is exacerbated by local wintertime snow removal. And every five or so years the cumulative effect causes enough damage to make some crossings rough for cars and light trucks. So the Museum hired Asphalt by George to remove the failed sections and replace with new hot mix.
First, the roadway was closed off. The defective sections were cut out with a concrete saw. Then a worker pried out the old material. A truck brought in a load of hot mix, and a compactor tamped it into the patchwork. Finally, some cracks and the seams where sealed with hot tar. (Thanks to the City of Snoqualmie Public Works Department for closing King Street to allow this work to occur safely!)
North Bend Way is a wider and faster crossing than King Street. Prevailing speeds can reach 70 MPH over this 160-foot long crossing, and it is a critical corridor so it is difficult to close the road. The patchwork effort there required a little more choreography to assure worker safety, but the theory was the same.
Completion of this crossing work represents two more summer projects the Museum can check off the list, and another task completed in time for Day Out With Thomas 2018.
