COMPARAÇÃO ENTRE A PAVIMENTAÇÃO FLEXÍVEL (CBUQ) E RÍGIDA (CONCRETO) NO TRECHO DO TREVO DE CAETÉ/MG AO TREVO DE BARÃO DE COCAIS/MG, NA BR 381

Abstract

This work analyzes a work on hard pavement (concrete) already executed and delivered to the Federal Government, and presents a construction simulation with the flexible pavement (Bituminous Concrete Machined hot - CBUQ), its location is in the stretch of the clover of Caeté / MG to the barão clover of Cocais / MG, on BR-381,. This work aims to compare the flexible floor and the rigid floor for the stretch, analyzing and simulating its respective dimensions and costs. Rigid floor has thicker thicknesses, its execution is in faster terms and its slow cure compared to the CBUQ and still little used here, has an estimated life of 20 years, because it is prepared with substances that coalesce better, hardly generate aquaplaning, as for the flexible pavement, in turn, it has a less dense layer and despite presenting in its execution methods that release traffic quickly it also takes longer to perform its work and with the same measures in width and length its execution is in slower terms due to its shape of its construction is much more used. The methods for calculating the sizing of the floors used by DNIT are elaborated by technical and empirical bases. To prepare the budget the professional, you must be very attentive to the points and characteristics of what you are preparing to perform. A visit to the work and the preliminary projects such as surveys and topography are essential to prepare the calculations in which the terrain will be prepared.
