RECYCLING PORTLAND CEMENT CONCRETE PAVEMENT

Quality aggregates for highway construction are in short supply in many parts of Minnesota. Although the current total supply is adequate, the distribution of sources results in localized shortages. It is sometimes necessary to import high-quality aggregates from distant locations. Haul distances can increase aggregate prices substantially, add to the overall project cost, and require the expenditure of sizable amounts of energy. One available source of aggregate is existing portland cement concrete (PCC) pavement currently in need of reconstruction. Reusing this aggregate would result in cost savings in aggregate-short areas, conserve natural resources, and conserve energy in the form of fuel savings when aggregates must be acquired from distant sources. A research study is described that was undertaken to determine the feasibility of recycling PCC pavement, evaluate the new recycled pavement, determine the cost-effectiveness of recycling versus conventional paving, and determine the amount of energy consumed and natural resources conserved. Economic and engineering factors led to the selection of a 16-mile segment of US-59 from Worthington to Fulda in southwestern Minnesota for the study. The in-place roadway, which was constructed in 1955 and consisted of 9-, 7-, 9-in-thick, 24-ft-wide, nonreinforced, D-cracked concrete pavement with soil shoulders, was broken, salvaged, and crushed. Material passing the no. 4 sieve was used for base stabilization and shoulder aggregate, and material retained on the no. 4 sieve but passing the 0.75-in sieve was used as the coarse aggregate for concrete paving. The project results are evaluated based on pavement performance and energy and cost comparisons. (Author)
