Details
Three commonly used surface aggregates, 2A, 2RC, and Driving Surface Aggregate(DSA) were placed side-by-side on Crowfield Road in Centre County. Each of the three aggregates was placed using two placement methods (tailgating and paver-placement) for a total of six test sections. These sections were monitored for changes in road surface elevation and shape for three years.
A paver places DSA on Crowfield Road in 2002.
