Objective

 

To analyze the Falling Weight Deflectometer (FWD) data and see if matches the results obtained from other tools.

 

 

 

 

Background

 

There are a total of 56 general aviation airports in New Mexico. The Department of Civil Engineering at UNM in partnership with the New Mexico Department of Transportation will be evaluating the airfield pavements of 10 airports every year for the next five years.

For this study, I chose to evaluate the runway pavement at Moriarty Municipal Airport in Moriarty, Torrance county in the heart of New Mexico.

General Information

 

Location: N 34 deg, 59.14 min, W 106 deg. 00.57 min.

Elevation: 6199 ft.

Runway 08-26

Length:7700 ft

Width: 75 ft.

 

 

 

 

FWD

 

An impulse load is applied by dropping a weight (ball) on the pavement and the resulting deflections are measured at specified distances from the point of load application using sensors (geophones). Three different loads of 9, 12, and 16 kips were applied in this case. The sensors are spaced at 0, 8, 12, 18, 24, 36, and 60 inches from the point of impact.

Conclusion

Using all the tools, the weak sections are located near to the two ends of the runway, that is at the zones of takeoff and touchdown.

ArcGis is a great tool to use to evaluate pavements

 

Future Work

Use more ArcGIS tools to analyze the various test results of a pavement evaluation test and in greater depth. Compare and contrast the results of various ArcGIS tools.

Look into the possibility of building a database for all New Mexico airports.
