The trial of a novel compound at a site in Chile has shown how structural improvements can be achieved for dirt road applications Although the Barrick Gold Pascua Lama operation is a surface mining site, the experience with this technology is equally applicable for use on haul roads in large quarries or for dirt roads expected to carry heavy loads. This is of particular importance for transport in remote areas where large loads such as pre-cast bridge sections or girders for example may have to be carrie

A new tunnel is forming an important link for a major Colombian highway - Mauro Nogarin reports Work on a major highway project is underway in Colombia, forming part of the Bogota-Buenaventura Corridor.
