Development of soil compaction analysis software (SCAN) integrating a low cost GPS receiver and compactometer.

Hwang J, Yun H, Kim J, Suh Y, Hong S, Lee D - Sensors (Basel) (2012)

Bottom Line: The SCAN is distinguished from other previous software for intelligent compaction (IC) in that it can use the results from various types of GPS positioning methods, and it also has an optimal structure for remotely managing the large amounts of data gathered from numerous rollers.For this, several methods were developed: (1) improving the accuracy of low cost GPS receiver's positioning results; (2) modeling the trajectory of a moving roller using a GPS receiver's results and linking it with the data from the compactometer; and (3) extracting the information regarding the compaction states of the ground from the modeled trajectory, using spatial analysis methods.The SCAN was verified throughout various field compaction tests, and it has been confirmed that it can be a very effective tool in evaluating field compaction states.

ABSTRACT
A software for soil compaction analysis (SCAN) has been developed for evaluating the compaction states using the data from the GPS as well as a compactometer attached on the roller. The SCAN is distinguished from other previous software for intelligent compaction (IC) in that it can use the results from various types of GPS positioning methods, and it also has an optimal structure for remotely managing the large amounts of data gathered from numerous rollers. For this, several methods were developed: (1) improving the accuracy of low cost GPS receiver's positioning results; (2) modeling the trajectory of a moving roller using a GPS receiver's results and linking it with the data from the compactometer; and (3) extracting the information regarding the compaction states of the ground from the modeled trajectory, using spatial analysis methods. The SCAN was verified throughout various field compaction tests, and it has been confirmed that it can be a very effective tool in evaluating field compaction states.

A compaction site (site B) for SCAN capability to a low cost GPS receiver mounted on a roller under similar environments of compaction work.

Mentions: GVKF and SCAN’s capability was tested and evaluated for its improvement of positioning accuracy and analysis of compaction properties obtained by a roller trajectory modeling with a low cost GPS receiver. For this evaluation, two tests were performed: (1) a utilization test for GVKF capability to improve positioning accuracy of the result provided by the low cost GPS receiver used by the SPP and SBAS signals mounted on a moving vehicle, and (2) a utilization test for SCAN (with GVKF), analyzing the roller trajectory and compaction properties from the roller’s low cost GPS results which result in precise compaction control work of the IC under similar compaction work environments. Figure 10 shows the selected test sites for the utilization tests of GVKF (site A) and SCAN capability (site B), respectively.
