The new index is composed of six indicator items and is based on total quantities used during the 1957-59 period. These items are common excavation, to indicate the price trend for all roadway excavation; portland cement concrete pavement and bituminous concrete pavement, to indicate the price trend for all surfacing types; and reinforcing steel, structural steel, and structural concrete, to indicate the price trend for structures. The old index, which has been in use for many years, was composed of five indicator items and was based on average quantities used per mile during the 1925-29 period. The same items were used as in the new index, except that surfacing was represented by portland cement concrete pavement only. The index based on 1925-29 base quantities and also converted to 1940 and 1946 bases will be published through calendar year 1961. In order to provide a suitable transition in use, the new index will also be published for the third and fourth quarters of 1961. Thereafter the 1925-29 index report will be discontinued. Use of the new base is in conformance with the effort of the Federal Government to prepare all index studies on a standard 1957-59 base period. Development of the new index is discussed in some detail in an article in Public Roads magazine, volume 31, No. 10, October 1961, available from the Superintendent of Documents, U. S. Government Printing Office, Washington 25, D. C., at 20 cents per copy. FOR OFFICIAL DISTRIBUTION |
