The Tampa International Airport has developed a permanent site for portable paving plants on the airport property. Ajax Paving Inc. is the first plant to use this site for a 33,000 yard taxi way extension. The project called for flexural strengths of 725 psi with an air content of 4.5%. To assist in overcoming aggregate challenges Ajax elected to use OptiFlo® 500 at a 5 oz./ cwt. This dosage also assisted in set control.

Premiere provided a self contained EPA friendly admixture trailer for use onsite. The trailer is comprised of six 1000 gallon tanks with quick connect hose fittings and amphonal computer connections. A camera and monitor are also provided to ensure accurate dosing.

“The Tampa airport project has gone quite well. We have experienced consistent air contents and strength throughout the project. Premiere Concrete Admixtures was very responsive to our needs in finding the right admixture to fit with the local materials. The Admixture trailer Premiere supplied was designed to meet all our needs; it incorporates self containment and is capable of quick tear down and set up. Each trailer is interchangeable with all our plants enhancing our flexibility. Premiere’s attention to service and product quality helps ensure our projects success.”

This project consisted of the reconstruction of Taxiway K and the adjacent apron for the new North Terminal at Detroit Metro Airport. It consisted of approximately 120,000 syds of 17 inch PPC pavement which was placed over a bituminous base. Taxiway K and the adjacent ramp were constructed in conjunction with the new North Terminal Project, which has become the home for all airlines other than NWA and affiliates at Detroit Metropolitan Airport. The specification for the concrete called for a modified P-501, and this project was the first time that the specification was utilized throughout the country.

The main difference in this P-501 specification was the use of blended aggregate mix using aggregates that are not prone to alkali silica reactivity issues. Comprehensive testing was performed and monitored on the materials daily to ensure compliance with the rigid specification. Another major challenge involved with the project was the compressed schedule under which the project was to be built. The project began in the spring of 2008 and was completed on time by fall of 2008 despite several setbacks in the schedule due to unforeseen underground utility conflicts.
