The three miles of fibrous concrete resurfacing in Greene County, Iowa were placed in September and early October, 1973. It was recognized in advance that cracking and other performance characteristics of the fibrous concrete sections and of the central sections would be major factors in the evaluation of the project. A low level aerial survey was made of the old pavement. During construction of the resurfacing, the aerial survey was checked to insure that cracks in the old pavement were referenced to the 100 ft. station marks placed in the resurfacing. The crack survey recorded herein was made in March and April, 1974. Those cracks in the resurfacing that are reflections of cracks in the underlying slab are identified by /\ marks. Observations (not detailed crack surveys) made in June, 1974 indicate that further cracking of the resurfacing has occurred since this report was prepared. In particular, there appears to be same additional longitudinal cracking over the widening joints.
