Abstract

The Road Project between the cities of Concepción and Vallemí (169 km), located in the northern area of the Paraguayan Oriental Region, in the Concepción Department, faced some challenges regarding the road construction materials. The absence of basaltic rocks, or other igneous rocks typically used in the country, in the road’s vicinity, forced the companies in charge to carry out numerous tests and trials to use the limestone rocks that were largely available in the surroundings of the project. The lack of information of the use of this rock type in regional road projects and the necessity to comply with the Paraguayan Ministry of Public Works were challenges to overcome to accept the use of this material in some of the structural pavement layers. This paper presents a description of the rock type, the locations of extraction areas and quarries, the tests carried out and the results obtained.
