 "description": "The Falling Weight Deflection (FWD) testing was used to determine the pavement strength and a Structural Number (SN) was estimated.  This is an AASHTO pavement design parameter where the traffic loads provided a required SN.  The thickness for each of the pavement layers could then be optimized to meet this strength need.",
