Workshops stress importance of in-place densities
By Bob Horan, P.E.
Proper compaction of an asphalt pavement is essential for long-term pavement performance. Studies show that a one percent reduction in in-place air voids can extend the asphalt pavement service life by at least 10 percent.
In order to bring this message to paving professionals, Asphalt Institute (AI) regional engineers created a workshop in 2016 entitled “Enhanced Durability through Increased In-Place Pavement Density” for state departments of transportations (DOTs) in cooperation with the Federal Highway Administration (FHWA).
