| Abstract | This research study, sponsored by the Federal Highway Administration, summarizes the field performance of eight high-early-strength (HES) concrete patches between 1994 and 1998. The patches were constructed under the Strategic Highway Research Program (SHRP) between June 1991 and July 1992 and were located in 5 States (Arkansas, Illinois, Nebraska, New York, and North Carolina) using existing State construction practices. The patches were constructed mainly with Type III cement, four different types of coarse aggregate, and three different types of fine aggregate. Similar types of air entraining admixtures, water reducers, and set accelerators were used at all except the North Carolina site. The patches were located in areas with varying environmental and traffic conditions. The performance criterion of interest was durability. Durability of the HES concrete was quantified over a period of 7 years using various indicators including compressive strength, static elastic modulus, rapid chloride permeability, and asphalt concrete (AC) impedance. The HES patches were also examined visually to locate any material- or durabilityrelated distresses. This report discusses in detail the effects of climate and material properties on the HES concrete durability. Some of the results of interest include the effect of water reducer type, curing method, and aggregate type on long-term durability. The report also presents comparisons of the rapid chloride permeability and AC impedance test results and the rate of strength gain for the mixes evaluated. Overall, the HES patches performed well with no obvious signs of deterioration. However, the results were not conclusive because the performance monitoring period was relatively short. There is a need for further research in the areas of long-term HES concrete mechanical properties and durability. |
