Concrete/Pavement Evaluation

Dielectric property of asphalt pavement specimens in dry, water-saturated, and frozen conditions Paper

Lanbo Liu, Tieshuan Guo

Proceedings Volume Ninth International Conference on Ground Penetrating Radar, (2002) https://doi.org/10.1117/12.462222

Read Abstract +

A series of experiments on asphalt pavement specimens with 1-GHz GPR system was conducted in the Connecticut Advanced Pavement (CAP) Laboratory. The objectives of these experiments are as follows. (1) Determining the dielectric property of the asphalt specimens; and (2) Correlating electromagnetic (EM) properties with void ratio and asphalt binder content ratio of asphalt pavement specimens. Results of this study can be used as the baseline to calibrate GPR field surveys for pavement assessment, as well as an indirect means to monitor the compaction process. The travel time for direct and reflected phases are the fundamental information for computing EM wave velocity. Supplemented by pre-existing information on geometry, void ratio, composition measured by other means, we were able to compute the dielectric constant of 30 pavement specimens. The major conclusions from these experiments are as follows. (1) In general EM wave velocity is highest in dry conditions, intermediate in frozen, and lowest in watersaturated conditions; Correspondingly, the dielectric constant is smallest in dry conditions, intermediate in frozen, and highest in water-saturated conditions. (2) EM wave velocity increases slightly with the increase of void ratio for dry samples. In contrast, it decreases significantly with a void ratio increase in water-saturated conditions. Correspondingly, the dielectric constant decreases noticeably with an increasing void ratio in dry conditions, and increases appreciably in saturated conditions. (3) The changes of EM velocity and dielectric constant for dry and saturated conditions can be predicted by the effective medium theory for porous media. (4) When the dielectric constant of the pore material is taken as the value of fresh water ice, the change of EM velocity and dielectric constant for the asphalt pavement specimens in frozen conditions cannot be correctly predicted with the effective medium theory. This implies that the pore water was not completely frozen when GPR measurement was taken. There are no significant changes in dielectric constant for dry and frozen conditions. (5) Variations in EM velocity and dielectric constant with asphalt binder ratio imply that a low asphalt ratio corresponds to a high void ratio so that in the lower end of the asphalt ratio, EM velocity has maximum fluctuation among the different conditions.

Read Abstract +

By its very nature, ground penetrating radar (GPR) is an ultra-wideband device (UWB), requiring a large range in frequency to penetrate the ground and image with sufficient resolution to solve practical problems. The increasing scarcity of electromagnetic spectrum and the proposed use of other UWB devices in 1998 caused the U.S. Federal Communications Commission (FCC) to initiate an inquiry (NOl ET Docket 98-1 53) to investigate permitting the operation of ultra-wideband devices (including ground penetrating radar) on an unlicensed basis under Part 1 5 of he FCC rules. Through 14 February 2002, the FCC had received over 9 1 0 comments in the inquiry (NOl 98-153) and on the Notice of Proposed Rulemaking (NPRM 00-163) issued in June, 2000. The First Report and Order (R&O 02-8) was issued on 14 February 2002. Before this, ground penetrating radar use was only officially permitted for those who had received waivers from the FCC or NTIA (National Telecommunications and Information Administration), who jointly regulate radio spectrum use in the United States. Legal waivers to manufacture ground penetrating radar were issued to U.S. Radar Inc., Time Domain Inc. and Zircon Corp. in June, 1999, and expiring with the R&O. Waivers to build or use ground penetrating radar were issued to the U.S. Geological Survey, U. S. Army and U. S. DOE by NTIA (or predecessors) from about 1976. The R&O issued on 14 February 2002 ". . provides for the operation of GPRs and other imaging devices under Part 15 of the Commission's rules subject to certain frequency and power limitations. The operators of imaging devices must be eligible for licensing under Part 90 of our rules. . ." "At the request of NTIA, the FCC will notify or coordinate with NTIA prior to the operation of all imaging systems." "GPRs must be operated below 960 MHz or in the frequency band 3.1-10.6 GHz." The FCC ". . intends within the next six to twelve months to review the standards for UWB devices and issue a further notice of proposed rule making to explore more flexible standards and address the operation of additional types of UWB operations and technology." This FCC rule impacts ground penetrating radar manufacture, sale and use in the United States (and in other countries whose rules are linked to FCC regulations).

In the last century ice bodies have changed significantly worldwide in response to climatic changes, apparently enhanced during the last decades, presumably owing to anthropogenic influence. Shrinkage of glaciers in the northern latitudes has been extensively documented; however, the behavior of glaciers in tropical or inter-tropical latitudes has been difficult to document. In Mexico, small glaciers are present in the highest mountains: Citlaltdpetl (5675 m), Popocatépetl (5452 m) and Iztaccthuatl (5286 m), all of them volcanoes. The glaciers of Mexico offer important clues about climate change at this latitude. Current inventory and monitoring of Mexican glaciers includes determination of glaciated areas and volumes. A survey has been carried out using ground-penetrating radar in order to get a figure of thickness and a preliminary volumetric estimate of an ice body of IztaccIhuatl volcano named Ayoloco glacier. A radar profile 415 m in length was obtained at a mean altitude of 5000 m with an azimuth of 190°, in a relatively flat area known as La Panza on top of the mountain. 100 Mhz antennas were used in the reflection mode with a separation of 2.5 m and a step-size of 2.5 m. A common mid-point survey was performed comprising 12 stations, at 0.5 m steps, to determine the wave velocity propagation in the ice-rock mixture that constitutes the glacier. Results yield a value of 0. 17 m/ns, which is close to the reported value for ice of 0. 1 6 m/ns. We find a layered structure perturbed by faulting at various inclinations, and an interface between the glacier and the underlying rock along a concave surface, shallow at the profile's extremes. There appears to be a transition at 50 m depth, from brittle to ductile ice. Since Iztaccihuatl volcano has many craters near the summit, we infer that this profile reveals the shape of one of the craters, which has been filled by the glacier's ice and a mixture of rock fragments and volcanic debris. The estimated upper volume of the Ayoloco glacier is 10.04 x 106 m3; this figure will have to be revised when more, perpendicular GPR transects are performed.

Numerical simulation of near-surface GPR in TE and TM modes Paper

Read Abstract +

Stimulated by the inquiry of using high frequency electromagnetic ground waves to communicate information among unattended ground sensors, numerical simulations of GPR performance in different near-surface geological settings were conducted. Two sets of 400 MHz GPR field data, one from Fort Richardson, Alaska, and the other one from Hanover, New Hampshire, were used to be the 'ground truth' to compare with numerical simulations. The numerical simulation algorithm we used adapts the finite difference time domain method, with a perfectly matched layer as the absorption boundary condition to truncate outbound waves. The signal impulse has a central frequency of 400 MHz, and the time step is 0.067 ns. We have simulated four cases: a combination of two radiation polarizations (TM and TE), and two geological settings, i.e., a sandy/gravelly half-space overlain by a silty/clayey layer (the case of Fort Richardson, AK), and a silty/clayey half-space overlain by sandy/gravelly layer (the case of Hanover, NH). The results depict the following implication. (1) More EM energy is radiated into the air as an air wave for the TM mode, and more EM energy will be sent into the ground when the TE mode is used, regardless of the geological setting. (2) Where a gravelly sandy half-space overlain by a silty/clayey layer, more EM energy will be trapped in the silty/clayey layer as a ground wave guide in the TE mode with almost no air radiation, when compared with the same radiation mode in the case of silty/clayey halfspace overlain by a layer of gravelly sandy. (3) For the geological setting of a sandy/gravelly half-space overlain by a silty/clayey layer, the TE mode only contains ground wave and the TM mode only contains air wave energy. This implies that for this case a far more complete separation of the air wave and the ground wave can be reached. These simulation results imply that transmission mode should consider the on-site geological setting when attempt to use the ground wave as a communication carrier.
