Propuesta del uso combinado de Base Macadam con Geotextiles No Tejidos en el proceso constructivo y diseño de la base del pavimento flexible con el fin de reducir los asentamientos en Chorrillos, Lima / Proposal for the combined use of Macadam Base with Non-Woven Geotextiles in the construction process and design of the flexible pavement base in order to reduce settlements in Chorrillos, Lima

La siguiente investigación tiene como fin colocar al Perú en una posición competitiva a nivel internacional mediante la mejora de su infraestructura vial, esto se plantea al proponer un sistema constructivo eficiente de la base de pavimentos flexibles en suelos blandos saturados de manera que estos no sufran grandes deformaciones permanentes y se reduzca el número y costo de mantenimientos que se aplican al pavimento. La necesidad de un mejor sistema de vías se ve reflejada en la brecha de acceso básico a la infraestructura a corto plazo en el sector Transporte. Debido a esto, se seleccionó una vía – caso de estudio que presenta serias patologías. Se pretende demostrar que la propuesta presentada en esta investigación reduce de manera considerable las deformaciones permanentes en la estructura del pavimento mediante el uso combinado de la Base Macadam y Geotextiles No Tejidos. El uso de ambos fue simulado en tramos de prueba sobre los cuales se realizaron ensayos de Deflectometría, un tramo reforzado con Geotextiles No tejidos y otro tramo sin reforzar. Se evidenciará una disminución en los asentamientos en el tramo reforzado y se elaborará un adecuado proceso constructivo basado en la construcción de las muestras usadas en los ensayos / The following research aims to place Peru in a competitive position at the international level by improving its road infrastructure, this is proposed by proposing an efficient construction system of the base of flexible pavements in saturated soft soils so that they do not suffer large permanent deformations and reduce the number and cost of maintenance applied to the pavement. The need for a better road system is reflected in the short-term basic access gap to infrastructure in the Transportation sector. Due to this, an avenue with serious pathologies in the pavement was selected. It is intended to demonstrate that the proposal presented in this investigation considerably reduces permanent deformations in the pavement structure through the combined use of Macadam base and Non-Woven Geotextiles. The use of both was simulated in test sections on which deflectometry tests were carried out, a section reinforced with Nonwoven Geotextiles and another section without reinforcement. There will be evidence of a decrease in settlements in the reinforced section and an adequate construction process based in the construction of the trials will be developed for the proposal. / Tesis

The topic of the master’s thesis is the design basic school for the first and second stage, which is located in the part of Pardubice named Pardubičky. It is a four-storey building, where you will find a total of 18 ordinary classrooms and other specialized classrooms (for example computer lab, physics lab, chemistry lab). The building is designed for 540 students. The building is built of brick Heluz system, the roof is flat. Each floor is hygienic facilities for both boys, girls, and for teachers and for persons with reduced mobility. In the ground floor are locker rooms, classrooms and sanitary facilities. In second floor are classrooms, facilities for teachers and cabinets. In the third floor are ordinary and specialized classrooms and fourth floor is engine room for air conditioning, and classrooms. Entry to the building is wheelchair accessible, the building has elevators.
