They are caused by mechanisms that for the most part have been observed and investigated by other According to the Caltrans method for flexible pavement design, the structural capacity associated with a pavement structure is represented by the gravel equivalent (GE). Association of Asphalt Paving Technologists Technical Sessions, 11-13 February 1985. This report illustrates that the AASHTO and Caltrans pavement thickness design procedures do not produce the same pavement structures for the same given inputs. (i) Section 891 – Local agencies must comply with design criteria and uniform symbols. These issues can affect the service life and drainage of both the existing and new pavement structures.
