FRAMEWORK OF PAVEMENT PERFORMANCE EVALUATION METHOD UNDER THE SCHEME OF PERFORMANCE-BASED SPECIFICATION

Abstract

Since technical standard was set as a performance-based specification, developing practical measurement methods for individual performance indicators have been urgent. This paper aims to present a framework of pavement performance evaluation methods under the technical standard and to activate discussion and research on specific evaluation methods. According to the contents of the technical standard, pavement performance can be evaluated not only by measuring the pavement in situ with performance indicator but also by using specimens properly substituted for the pavement and/or calculating the performance indicator based on measured values of indicators which correlate with the actual pavement performance.
