CALL FOR ABSTRACTS
PAVEMENT NONDESTRUCTIVE TESTING WITH EMPHASIS
ON ESTIMATING SUBGRADE PROPERTIES
Geo-Institute of the ASCE
Geo-Denver 2000 Conference
Denver, Colorado, August 3-8, 2000
Nondestructive testing (NDT) of pavement has been extensively used by
various highway agencies to estimate properties of both subgrade and
pavement materials. Examples of nondestructive testing of pavement include
deflection measurements, seismic techniques and ground penetrating radar.
In addition, analysis of NDT data ranges from simple empirical formulas to
more complicated backcalculation of layer moduli, spectral analyses and
artificial neural networks. These NDT and analysis techniques have been
used to different degrees for research purposes and for typical pavement
evaluation and design applications.
Pavement performance is largely affected by subgrade properties such as
compaction, stiffness, stability, drainage, freeze and thaw, and volume
change. Nondestructive testing and analysis that detect these subgrade
properties and others that affect pavement performance are of large
interest to pavement and materials engineers.
The pavement committee of the Geo-Institute is planning to sponsor a
session entitled "Pavement Nondestructive Testing with Emphasis on
Estimating Subgrade Properties" in the Geo-Denver 2000 Conference. Papers
are solicited for presentation at the session and for publication in the
conference proceedings. Papers based on theoretical modeling or
experimental observations are invited. Papers that emphasis estimating
subgrade properties that affect pavement performance are encouraged.
Authors are requested to express their interest to prepare a paper by
submitting a 300-word abstract by March 15, 1999, to Sandra Houston,
Department of Civil and Environmental Engineering, Arizona State
University, Tempe, AZ 85287-5306. Authors will be notified about the
acceptance of their abstracts by May 1, 1999. Complete papers will be due
October 1, 1999.
