EVALUATION OF PERFORMANCE AND COST-EFFECTIVENESS OF THIN PAVEMENT SURFACE TREATMENTS. INTERIM REPORT #2

This is the second report to result from the subject study. It represents the first major effort to evaluate the available data on "thin pavement surface treatments" in Oregon and to define "cost effectiveness" for this purpose. The 87 projects studied here were constructed in 1984, 1985, and 1986. This report includes pavement condition data collected annually through 1989. Three different "cost-effectiveness indices" are defined and used to compare similar types of treatments. The Longevity Cost Index (LCI) is based on the median service life, price, and traffic loading of each treatment type. After more of the treatments fail, this index is expected to be the most meaningful of the three. It is applied here in a preliminary effort to compare the cost-effectiveness of two types of chip seals. The two other indices, based on changes in pavement condition, are also explored for comparing the treatments. As a supplemental effort, this report addresses the question, "Which treatment is the most appropriate in a given situation?". To accomplish this, an outline of selection criteria for various treatments is presented. This is based on experience in Oregon and the available literature.
