Abstract

This article presents two experiences relating to surfacing techniques for Low-Traffic Volume Roads, which are part of tertiary networks. The first took place in Chile as part of a conservation of rural roads program, which has been systematically implemented since 2003 and is known as the “Programa de Caminos básicos” (Program of basic roads). The second was carried out in the Land and Pavement laboratories at the Julio Garavito Colombian School of Engineering, and its purpose was to compare commercially available admixtures, including cement, in order to maximize the stabilization of a road surface used on 23 km of the road that connects San Pablo, one of the Colombian municipalities most affected by the armed conflict, with Cañabraval in the south of the Bolívar department.

At the end of the article some considerations are presented on road surfaces in terms of the so-called technological road surfacing innovations regarding the need to have sufficient drainage on rural roads and their subsequent preservation once engineered.

Keywords: Tertiary network, Stabilization, Road surfaces, Basic roads, Preservation
