La deformación permanente en las mezclas asfálticas y el consecuente deterioro de los pavimentos asfálticos en el perú

Abstract

In the last t 10 years Peru has promoted a favorable policy for the construction of Road Works across the entire territory, having executed more than 15,000 kilometers of roads with asphalt pavements, according to reports by the Ministry of Transport and Communications, the entity responsible for national road network. Faced with this reality there is an urgent need to improve the technology of asphalt pavements in Peru so that they reach the life for which they were designed. Permanent deformation is one of the failures of most concern in pavement deterioration, being necessary to know their fundmental causes in order to take measures during the development of project, construction, and future maintenance. Therefore it is urgent to conduct several tests analysis in Peru usingspecialized laboratory and field equipments to evaluate the pavement structure to prevent permanent defonvation. This leads to the need for developing new technical specifications for asphalt mixes which depending on the results of the analsys, can include the use of modifiers such as polymers, rubber powder and the application SUPERPAVE technology for better characterization of the constituent asphalt mixes with the purpose of increasing the durability of asphalt pavements.
