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.

f4-sensors-12-02351: Spatial object models of SCAN.

Mentions: Two types of spatial object models were used for modeling the vibrating roller’s continuous trajectory and analyzing compaction states of ground. The filtered data converted into point objects include the following properties: 3-D position, velocity obtained from GPS, and compaction properties such as degree of compaction, CMV, RMV, and vibration frequency of the roller. Next, the point objects were converted to continuous quadrangle cell objects having all properties of the point objects. Figure 4 shows the converting and creating processes of the spatial object models.
