ANÁLISIS RESISTENTE DE VIALES DE JABRE ESTABILIZADOS CON CEMENTO

Abstract

The main goal of this paper is to determine the resistant properties of a stabilized jabre soil with cement CEM II BL 32,5N, analyzing the influence of the cement dosage (from 0 to 10%) and the curing time (2, 7 and 21 days) on the strength compression resistance of the soil, and establish some technical recommendations for its use that comply with the specifications of the General Technical Prescriptions of Roads and Bridges Works (PG-3). The results indicate jabre is a granular material with good granulometry properties such as plasticity and compaction. In this stabilization, it has been verified the significant influence of % cement and curing time. According to the minimum required strength compression in PG-3 (1.5 MPa) it was concluded that the minimum strength compression is achieved with a cement dose of 3.5% at 21 days, and 5% cement at 7 days by applying a 100% PN compaction to the mixture. Lower values of % cement for these curing times would make the work unviable due to lack of strength.
