Traffic speed deflectometer (TSD) provides an efficient way for evaluating pavement condition.
It is important to understand the uncertainties of data collection and develop cost-effective use
of TSD measurements for decision making. This presentation will focus on advanced modeling
and analysis of TSD on flexible pavements in four aspects: 1) the relationship between
pavement responses under stationary and moving tire loading; 2) the impact of dynamic
loading due to pavement roughness on TSD measurements of deflection velocity and
deflection; 3) the backcalculation of pavement modulus; and 4) the prediction of critical strains
from TSD measurements. The application of TSD for project level pavement design and
network level pavement management will be discussed.
