An approximately 4-mile-long road construction project on US-23 in Alcona County involved cold milling off the existing asphalt, milling off black base material, rubblizing concrete underneath the black base material, and paving with asphalt. The approximately $2.5-million project began in May and it was completed by September. Bolen Asphalt Paving, of East Tawas, was the prime contractor for the project.
"The project was difficult because we had to maintain traffic. We had to mill the asphalt off of the top in one cut," Bruce Bolen, project manager for Bolen Asphalt Paving, said.
"We broke the job into three parts. One part was a three-lane section at the northern end of the job and the rest of it, which was approximately 2 miles long, was a two-lane section," Bolen said. The two-lane section was broken into two parts. Each part was 1-mile long.
"I guess the challenging part was working on the two 1-mile sections. Coordination of the schedule was very tight as far as getting the black base material milled off, getting the concrete rubblized and then placing the new asphalt pavement before the road started to deteriorate from the traffic being on it," Bolen said. He said that the tight time frame they had to work in was a challenge.
Equipment used on the project included an Ingersoll Rand Blaw-Knox paver; Cat rollers; one Ingersoll Rand roller; one Cat grader; and one Cat excavator.
The project involved placing approximately 30,000 tons of asphalt. Bolen Asphalt Paving used 13A, 3E1, 4E1, and 5E1 asphalt mixes on the project. Rubblizing totaled approximately 54,000 square yards and milling totaled approximately 65,000 square yards.
The Michigan Department of Transportation's delivery engineer for the project was Thomas Hilberg, of the Alpena Transportation Service Center.
Subcontractors included Shaw Contracting, of Kawkawlin (milling); Antigo Construction, Inc., of Antigo, Wis. (rubblizing); Hunt Brothers, of East Tawas (concrete work); and Dale Dukes & Sons, of Big Rapids (guardrail).
