Abstract
Specifications are used to convey information concerning desired products from a buyer to a seller or potential seller, they are used as a basis for competitive bidding for the delivery of products, and they are used to measure compliance to contracts. There are four types of specifications generally recognized in the construction industry: (1) proprietary product, (2) method, (3) end-result; and (4) performance. The current general state of highway specifications is represented by end-result specifications. In the future, efforts will be made to mathematically tie the end-result quality characteristics for the product to its performance; these will be referred to as performance-related specifications.
