Abstract

This paper presents the development and implementation of a modified compact asphalt method aimed at significantly reducing construction and road closure times for both maintenance and new road projects. Traditional asphalt pavements are constructed in multiple layers—base, binder, and wearing—requiring several sequential operations. The new approach introduces a specially designed asphalt mix (AC 45 B/T S), capable of being laid in a single thick base/binder course (20–22 cm) with a very thin wearing course (2 cm) simultaneously. The method has proven beneficial for high-traffic maintenance projects by eliminating joints and reducing process steps.
