Evaluation of the Pavement Structural Condition at Network Level Using Falling Weight Deflectometer (fwd) Data
Large amounts of seal coats and thin overlays are applied every year by state highway agencies to improve the surface condition of pavements, but these measures have not successfully prevented the problem from reoccurring. As a result, the overall pavement condition keeps deteriorating because of the structural deformation of pavement layers and the subgrade. To make effective decisions about t...
متن کاملDevelopment of Asphalt Dynamic Modulus Master Curve Using Falling Weight Deflectometer Measurements, TR-659
The asphalt concrete (AC) dynamic modulus (|E*|) is a key design parameter in mechanistic-based pavement design methodologies such as the American Association of State Highway and Transportation Officials (AASHTO) MEPDG/Pavement-ME Design. The objective of this feasibility study was to develop frameworks for predicting the AC |E*| master curve from falling weight deflectometer (FWD) deflection-...
متن کاملSimplified, Rational Approach to Falling Weight Deflectometer Data Interpretation
The authors present a simple elastostatic approach to estimate a suitable subgrade modulus from falling weight deflectometer (FWD) data. An effective surface modulus is defined on the basis of Boussinesq-Newmark equations. Deviations between the model assumptions and actual in situ conditions are reflected in the effective surface modulus variation with radius. The variation indicates which sen...

متن کاملNeural Networks Analysis of Airfield Pavement Heavy Weight Deflectometer Data
The Heavy Weight Deflectometer (HWD) test is one of the most widely used tests for assessing the structural integrity of airport pavements in a non-destructive manner. The elastic moduli of the individual pavement layers predicted from the HWD deflection measurements through inverse engineering analysis are effective indicators of pavement layer condition. The primary objective of this study wa...
