www.acpa.org Quarter 4, 2018 17 State Aid Project (SAP) 43-603-032, McLeod County, MN CONTRACTOR: PCI Roads OWNER: McLeod County Public Works ENGINEER: McLeod County Public Works When an existing bituminous roadway needed to be rehabilitated, the McLeod County Public Works department decided on a concrete overlay to provide a long lasting, durable, pavement that did not have the future road-user delays associated with traditional bituminous maintenance. State Aid Project (SAP) 043-603-032 was a 6.4 mi. concrete overlay on County State Aid Highway (CSAH) 3 in McLeod County, which is located approximately 60 miles west of the Twin Cities. The concrete section consisted of 6 in. of undoweled, plain concrete that was jointed in 6 ft. by 6 ft. panels with a tied shoulder, all of which was placed in a single 32-foot wide operation. Some of the bituminous millings taken from this project were used for part of the shoulders, while the remaining materials were stockpiled and will be used on future County projects, thereby minimizing the use of virgin materials. The contractor encountered some random areas where the old transverse cracks in the bituminous pavement were very deep, but to address the problem, the areas were monitored closely, and filled with washed sand to prevent formation of paving lugs and to keep the con- crete quantities in line. As a result of the expert project management and execution, along with the effective communications, PCI finished the project on time, creating a durable roadway that will handle vehicle traffic of all types for many years.

OWNER: City of South Bend, Department of Public Works ENGINEER: Abonmarche Consultants, Inc. Concrete was once again the pavement of choice in the ongoing efforts to improve urban aesthetics and restore neighborhoods, while also providing a longer service life of arterial routes into downtown South Bend. This project constitutes a segment of a multi- phase corridor improvement on Western Avenue, and it runs approximately 2,500 lineal ft. The project scope included reconstruction of the existing pavement and redesign of traffic flow patterns to include designated turn lane; permeable parking spaces; and a mix of full-depth concrete and a thin concrete overlay. The project also included placement of new underground utilities, storm/sanitary separa- tion, and construction of new sidewalks and curbs, and the addition of updated street lighting. Selge Construction placed 10 in. of full-depth pave- ment was placed where new underground utility work was performed, as well as a 4 in. concrete overlay over existing asphalt pavement. In all, the project con- sisted of 3,800 SY of 10 in. full depth concrete, and 4,300 SY of 4 in. concrete overlay, and 727 SY of 6 in. concretes. The project also included 2,500 SY of 4 in. sidewalks; 2,653 lineal ft. of 6 in. and 8 in. curb; 1,300 lineal ft. of ribbon curb; and 1,050 SY of permeable pavers in the designated parking lanes. This project and other corridor updates are well served by concrete pavement because it provides a longer service life, improved night-time visibility, and a reduced urban heat island effect.
