OWNER: Metropolitan Topeka Airport Authority ENGINEER: WSP The Topeka Regional Airport has been in service since World War II, so when it was time to replace the main runway and perform other upgrades, the owner speci- fied concrete. Originally built as a military base and later expanded to service both commercial and private air traffic, as well as both the Kansas Air National Guard and Army National Guard), the main runway (13/31) has been in use for many decades utilizing the original concrete pavement. Emery Sapp & Sons, Inc., had the challenge of replac- ing the runway while maintaining military and com- mercial air traffic. The project was divided into two phases to be constructed over two years. Phase 1, an $18 million project, was started in Feb- ruary and completed in October. Crews completely removed 6,500 ft. of main runway and replaced with 16.5 in. doweled JCPC pavement. The project also involved removing 154,000 SY of existing runway and taxiway; grading more than 265,000 CY; placing 123,000 SY of lime treated subgrade; and placing 54,000 CY of concrete and 20,000 CY of cement- treated permeable base. Additional features include over 18,000 lineal ft. of under drain, a new lighting and navigational system, new pavement markings. This project was completed on time and under budget, with no accidents or safety-related incidents, and all 112,000 SY of concrete pavement were placed with no corrective ac- tions needed.

The overall project duration was 330 calendar days, with liquidated damages set at $100/ minute for any delays in reopening taxiways as specified, as well as $3,000/day penalties for exceeding the 330-day schedule. The typical new taxiway section was comprised of new underdrain trunk lines and herring bones, new light can conduits and light cans, a P-401 bituminous leveling course on top of 6 in. of soil cement, fully rebuilt asphalt shoulders, and a 20 in. concrete pavement. The non-reinforced/reinforced concrete thicknesses were: 20 in., 20 to 26 in. thickened edges, and 16 to 20 in., and a 16 in. shoulder ramp. Typical slab sizes were 25 ft. by 25 ft., with two of the phases having outside slabs measuring 12.5 ft. wide by 25 ft. long. The smaller slabs were reinforced, slip-formed, and extended for a total length of approx. 900 linear ft. in one phase and 725 linear ft. in another.
