    Method-type specifications penalize a competent asphalt paving contractor by requiring the contractor to use prescribed equipment, materials, and methods to construct a particular pavement. End-result specifications, on the other hand, allow the contractor to use his available resources to accomplish the required end product in the manner of his own preference.

    The Indiana State Highway Commission let to contract a paving project under end-result specifications. This contract, awarded to Magaw Construction, accepted the asphalt content, aggregate gradation, and pavement surface smoothness on the basis of statistical-type specifications. The quality control exercised by the contractor was excellent, with the penalties assessed being equal to only 1.24 percent of the value of the paving work.

    A lack of knowledge by state personnel of the significance of end-result specifications and differences in sampling and testing techniques have, in the past, caused the assessment of many of the penalty points. The differences in the results obtained could be reduced on future projects, however, through the use of a certified asphalt technician approach to end-result specifications.
