Concrete Pavement Progress www.acpa.org 22 Muskogee Turnpike (MU-MC-42), Wagoner County, OK CONTRACTOR: Koss Construction Company OWNER: Oklahoma Turnpike Authority ENGINEER: Craig & Keithline, Inc. The construction of this project on Oklahoma’s Musk- ogee Turnpike was a challenging project that required a major commitment from Koss Construction and their subcontractors. Plans called for the project to be completed in 370 days, however, days were added to the contract for additional work that was added to the contract after work was in progress. Koss was tasked with removing the existing four lane highway, which was a difficult and time-consuming operation. The existing concrete was crushed and used as aggregate subbase in the roadbed. This proved to be both cost effective and environmentally responsible, as it reduced the amount of virgin aggre- gate by 100,000 tons. Koss placed the 10.5 in. doweled, jointed concrete pavement over 12 in. of subbase material. In all, Koss crews placed 450,300 SY of concrete, for the construction of 36.32 lane miles of highway pavement. The project was divided into five phases of construc- tion, with each phase divided into two parts. The contractor’s control department continually tested the concrete to ensure a quality pavement was con- structed. Koss QC Technicians used a type B pressure pot and a Super Air Meter to monitor air content and air spacing in the plastic concrete. Koss project superintendents regularly talked with landowners and business owners to keep them informed before any traffic switches or lane closures were activated. Arrow boards were placed at the be- ginning of the project in both directions to benefit the traveling public. The skill and hard work of the project team resulted in a quality reconstruct of this important toll highway. Divided Highways (Rural) US119 CoLine-Crossover Rd, Mt. Pleasant, PA CONTRACTOR: Golden Triangle Construction Co., Inc. OWNER: Pennsylvania DOT ENGINEER: SAI Engineers Golden Triangle Construction Co., Inc. was awarded this two-year, $37.8 million reconstruction project by the Pennsylvania DOT (PennDOT). This highway reconstruction project was located on State Route 119 in East Huntingdon, PA. The roughly 5-mi. long, two-lane divided highway project included more than 190,000 SY of 12 in. jointed concrete pavement; almost 3.4 miles of upgraded drainage and stormwater retention systems, median upgrades with concrete barrier separation; paving inside shoulders; and mine stabilization. Some major project highlights include: cement soil sta- bilization, a roller compacted concrete truck-inspection area, recycled concrete for site stabilization and toe bench rock, ASR concrete, long-life concrete, roughly 14,500 lineal ft. of concrete glare screen barrier, and mine shaft repair with concrete support columns. A winter shutdown was mandated, during which no work could take place from November 1 to April 1. With the amount of work that needed to take place in two seasons, the winter presented a challenge to an already tight schedule. A late warm spell in the first year allowed the crews to work into November and December for smaller concrete pours. This was a huge help as progress was delayed in late fall due to some unforeseen conditions and changes to the subgrade and pavement design. In the second year, work on a mainline section was halted for a month in order to allow the utility contrac- tor to move a line that would have been exposed if not lowered under the subgrade. Also, in the second year, large rain storm events delayed concrete paving almost a month. It was difficult to coor- dinate concrete pours with the weather and other project demands, but crews once again worked weekends when rain was not forecasted. Despite the complexity of the project, as well as unfore- seen delays, Golden Triangle completed the work in just 20 working months.
