What Percentage of Our Roads Are Asphalt (Versus Concrete)?: A Systematic and Objective Way to Measure

This article describes an analysis method that can be used to track pavement type (asphalt versus concrete surface) across the federal highway system. The data used in this method comes from the Highway Statistics, Section IV: Highway Infrastructure document, published by the Federal Highway Administration (FHWA). This annual report presents an extensive array of highway inventory information that is submitted to the FHWA each year by each state’s transportation department. The author describes the unit of measurement (number of centerline miles) and how that impacts the total accounting. Surface types are reported in the document as bituminous, concrete, or unpaved and the report also categorizes functional classes of roads: interstates, other freeways and expressways, principal arterials, minor arterials, and major collectors. Minor collectors and local roads are not included in this analytic method. The author presents a chart of data from 2016, with a discussion of both national trends and state-by-state analysis. One map illustrates the percentage of asphalt-paved roads in each U.S. state.
