Development of structural condition thresholds for TSD measurements
… deflection thresholds to classify the pavement structural condition obtained from the TSD for a small subset of the Pennsylvania secondary road network. The results of the field evaluation included: (1) repeatability of the TSD, (2) ability of the TSD to identify pavement sections with varying …

Network Level Decision-Making Using Pavement Structural Condition Information From The Traffic Speed Deflectometer
Pavement structural condition plays a critical role in the rate of pavement deterioration, yet most state highway agencies' network-level decision-making processes are primarily based on surface distresses. Despite the limitations of the traditional structural condition measuring devices, some …

Cement Stabilized Crushed Stone Base Course Strength and Stiffness Analysis
… of Pavement Structures (1993 AASHTO) [1] for structural design of pavements. A growing portion of DOT’s are beginning to implement the Mechanistic-Empirical Pavement Design Guide (MEPDG), referred to as AASHTOWare Pavement ME [2]. The 1993 AASHTO flexible guide applies empirically derived …

Network-Level Structural Condition Data for Sustainable Pavement Asset Management
… of pavements, they do not directly capture the structural capacity that influences long-term performance. As a result, agencies risk selecting treatments that are either insufficient for addressing underlying structural deficiencies or unnecessarily conservative, leading to inefficient …
