QUANTIFYING THE EFFECT OF PAVEMENT PERFORMANCE CHARACTERISTICS USING PARTIAL DERIVATIVES

Asphalt content, aggregate characteristics, pavement layer thickness and degree of compaction, and initial pavement smoothness are keys to quality control in asphalt pavement construction. These measurable items are routinely checked during the construction process. The overall pavement performance life may be significantly affected when the specified characteristics of those items are not achieved in situ. Quantification of their effect on pavement performance is essential for quality roadway construction and rational pay adjustment factors. An approach is presented for estimating the expected loss (or gain) in pavement performance life resulting from any in situ deviation in performance-related characteristics from their specified values. The estimation is a simple exercise in the application of mathematical partial derivatives.
