OROBIO, ARMANDO. CONSIDERATIONS FOR DESIGN AND CONSTRUCTION OF GRAVEL SURFACED ROADS STABILIZED WITH CALCIUM CHLORIDE. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.165, pp.93-100. ISSN 0012-7353.
The agribusiness sector utilizes sugar trains in some regions of Colombia. These vehicles travel on gravel surfaced roads as a part of the production process. Road maintenance and dust suppression have become an important factor for these industries. Stabilization of gravel surfaced roads with calcium chloride was analyzed on a test section. Calcium chloride proved to be an efficient dust suppressant to be used in those regions. However, the performance of the gravel surfaced roads resulted to be a critical factor in controlling dust emissions. This paper presents some recommendations for the design and construction of gravel surfaced roads stabilized with calcium chloride. These recommendations are addressed to improve the effectiveness of stabilizations as a dust suppressant means and to improve the performance of the roads to reduce investment in maintenance.
