Caltrans says it will apply a sand treatment in an attempt to smooth a section of Highway 1 north of Cambria that bicyclists said was too rough.
The treatment will first be applied to a short test section of the highway. The process involves a sprayed application of asphalt emulsion, followed by a covering of clean sand or fine aggregate.
Caltrans says the treatment was tested on a segment of Highway 198 in Monterey County. The agency worked with the UC Davis Pavement Research Center to come up with a solution to the rough highway surface. Several pavement treatments were tested by bicyclists, and Caltrans says the sand treatment resulted in the greatest improvement.
Caltrans says if the treatment on the test section of Highway 1 is a success, it will be applied to the entire roadway north of Cambria that received a chip seal last fall.
The project is expected to cost $1.5 million.
