Open friction courses on an asphaltic concrete base: A seven-year progress report
Abstract
The performance of two open-friction courses (OFC) having 1/2 in. and 1/4 in. maximum-sized aggregates - and their adjacent conventional New York State 1A top-course (control) is documented over the final 4 years of their 7-year design lives. The pavements were evaluated by analysis of mix properties and surface performance. The physical properties examined by means of extracted pavement cores were aggregate gradation, binder penetration and viscosities, and void content. Testing of frictional performance, rut depths, microtecture and macrotexture, rideability, and cracking were used to evaluate the pavement's surface performance.
