Avaliação da eficiência da colmatação de fissuras no pavimento rígido, da obra da BR 101-Nordeste, lote 05, pela aplicação na injeção de calda coloidal de microcimento.

Abstract

This thesis aims at evaluating the efficiency of clogging of cracks in the paviment of Portland cement concrete, the work of BR-101-Northeast, Lot 05, recovered by application of the injection spray colloidal microcement It uses resources with methodological literature, technical visits and preparation of case study, present a brief history about the types of paviments of Portland cement concrete and its properties, deterioration and rehabilitation of these types of paviments and the description of the pathology detected. In the evaluation of paviment were used axial compression tests and optical microscopy, observing and cracking resistance parameters. Presents and analyzes the results obtained by application the injection of spray colloidal microcement syrup into cracks of the pavement of the work mentioned. It was concluded that recovery of pavement Portland cement concrete application of the technology of injection spray microcement treatment of the pathology identified in this particular work, was less efficient with regard to clogging and may thus influence on changes in physical and mechanical characteristics especially with regard to durability. It is suggested then that monitoring is done on that floor through the fatigue test, or others as a means of preventing and until same investigation on his life.
