URBAN PAVEMENTS /IN PORTUGUESE/

TECHNICAL AND ECONOMIC CONSIDERATIONS ARE NEEDED IN URBAN PAVING, FOR THE SELECTION OF HIGHWAYS. IN THE SELECTION OF THE PAVEMENT, THE GREATER DIFFICULTY IS THE ESTABLISHMENT OF THE CORRELATION BETWEEN THE TYPE OF PAVEMENT AND THE PAVEMENT DURABILITY OR PAVEMENT LIFE. PERIODIC TESTS MUST BE DONE ON HIGHWAY NETWORKS OR IN EXPERIMENTAL ROADS TO DETERMINE THE PAVEMENT LIFE OF SEVERAL TYPES OF PAVEMENTS. IN THE FIRST YEARS OF USE, REPAIR COSTS ARE LOW, BUT BY AND BY FAULTS APPEAR MORE FREQUENTLY AND THERE IS A LIMIT WHEN THE PAVEMENT RECONSTRUCTION IS THE ONLY JUSTIFIED ECONOMIC DIRECTIVE. /RRI/
