Title: Evaluation of Aggregate Performance in Pavement Concrete
Author(s): H. S. Sweet and K. B. Woods
Publication: Journal Proceedings
Appears on pages(s): 1033-1040
Abstract:This paper consists essentially of a review of published information on aggregate as a variable influencing the durability characteristics of portland cement concrete. The paper covers the evaluation techniques which have been used in field performance studies, particualarly with respect to isolating the causes of the performance. Some emphasis has been placed upon such studies made in Indiana where it has been found that many miles of concrete pavements have deteriorated when certain coarse aggregates were useed regardless of other variables, such as cement, fine aggregate, traffic, etc. In contrast, many more miles of Indiana pavements, constructed with other coarse aggregatees, are in excellent condition after as many as 20 years of service. The paper mentions but does not treat the reactions between high alkali cements and certain aggregates. It is concluded that aggregate acceptance tests in common use are not adequate to differentiate between good and bad aggregate materials.
