(Silver Award)  Jack Edwards National Airport Improvements, Gulf Shores, Ala.

Contractor: A.G. Peltz Group, LLC            

Owner:  Jack Edwards National Airport

Engineer:  Barge, Waggoner, Sumner and Cannon, Inc.


As tourism in this resort city and overall region has increased, the Jack Edwards airport has seen increased demand for additional aircraft apron areas that can accommodate all types of aircraft, including heavy aircraft.  In response to these increasing demands, the Federal Aviation Administration granted funds to construct a new heavy aircraft apron.

A.G. Peltz Group* won a competitive bid to construct the new heavy aircraft apron. The scope of work included taking a greenfield site and performing the required grading, drainage, base, pavement, aircraft tie downs, and lighting for the new apron. The pavement section consists of a 6 in. P-304 cement treated base layer and a 15 in. P-501 plain jointed concrete pavement layer.

A.G. Peltz performed both the cement-treated base and concrete paving required to complete the project. The pavement was constructed in 30 ft paving widths to shorten the duration of the pavement placements and try to recover time lost during the grading phase of the project.  In spite of an unusually wet spring that caused delays, the 27,555 SY heavy aircraft apron now serves the air travel needs of the region, and allows aircraft up to 737 class. This apron will now allow the airport to accept a larger volume and larger size of aircraft.


(Gold Award)  Reconstruction Project at Northwest Missouri Regional Airport, Maryville, Mo.

Contractor: Ideker, Inc.

Owner:  City of Maryville, Missouri          

Engineer: Jviation, Inc.

Pavement evaluations on Runway 14-32 at the Northwest Missouri Regional Airport in Maryville, Missouri, resulted in low Pavement Condition Index numbers for a portion of the runway, north turnaround, and the northernmost taxiway connector from the apron.  Also, deterioration of the north 4,000 ft. of the runway since 2011 required emergency replacements of select concrete panels on an annual basis.

Ideker, Inc. proved they were up to the task of completing this challenging project. Because of these factors, a comprehensive reconstruction project was required and involved the removal and replacement of the existing pavement.  The project involved pavement demolition; fly ash stabilization of the subgrade; in-place recycling of the existing 6 in. concrete and reuse as aggregate base course; drainage pipe installation; underdrain construction; and a new edge lighting system.  

The airport was closed for the duration of the project to allow for the complete removal and replacement of the northernmost 4,000 ft. of runway pavement.  In all, 38,000 SY of 6 in. concrete pavement was placed over the recycled concrete aggregate and subgrade. A geotextile fabric between the subgrade and base course minimized the amount of fines entering the base course.

Weather delays and unanticipated poor subgrade conditions complicated the project, but the contractor and other project partners worked through these issues together to keep the project moving forward with minimal delays. 

Ideker used stringless grade control for establishing the finished subgrade elevations, finished recycled concrete base course elevations, and placement of the concrete.  Ideker also sequenced paving lanes so to avoid driving on the subbase during paving.  

The consistent thickness results and profilograph results—with no deficiencies to correct—are a testament to the tight grade control and attention to detail that was achieved during the project.  

In addition, the specifications were exceeded for flexural strength gain for this project. The smooth ride of the new runway exhibits the high quality of workmanship that was achieved on this project.
