Cost-Effectiveness of Open Graded Base Course with Doweled and Nondoweled Transverse Joints.

摘要

This study aimed to investigate the performance of 20-year-old concrete pavements, both doweled and nondoweled, in three areas of Wisconsin: US 18/151 in Iowa and Dane counties: 17 sections of pavement. Constructed in 1988 with 9-inch portland cement concrete and a mixture of sealed and unsealed transverse joints, the Iowa County sections were nondoweled and the Dane County sections were doweled. Sections featured seven unique design factors and five pavement bases over 4-inch drainage pipes; WIS 29 in Brown County: four test sections. Built in 1988 with 10 inches of PCC over a 4-inch permeable base, all over a 4-inch dense graded base with 6-inch drainage pipes, these sections featured both sealed and unsealed joints at doweled and nondoweled seams; and US 151 in Columbia and Dane counties: four sections. These sections of 10-inch PCC were constructed in 1991 over five bases and 6-inch drainage pipes.
