Abstract
Description
El proyecto tuvo como propósito el diseño geométrico y estructural para la restauración de
pavimento del Bulevar Fuerzas Armadas en La Lima, Cortés mediante el uso de whitetopping.El
objetivo de esta restauración de pavimento era proporcionar un tránsito vehicular seguro que
cumpla con todos los códigos nacionales de construcción para carreteras establecido. Para el
diseño de la obra de whitetopping se tomaron aspectos fundamentales como ser estudio
topográfico, calidad del suelo, distancias, ángulos y pendientes del bulevar, tránsito vehicular y
medición de daños del pavimento existente para poder cumplir con todos los estándares de
calidad establecidos. La metodología empleada es cuantitativa, porque los valores del dominio de
variación son contados y medidos. El diseño del alineamiento vertical y horizontal se sostuvo
respetando el diseño original de la carretera, salvo pequeños cambios en las pendientes,
respetando siempre los valores máximos y mínimos permitidos por la norma AASHTO. El
pavimento rígido fue diseñado para un periodo de 10 años y el valor promedio de CBR fue de 34
y un módulo de reacción de 108 mpa/m lo cual permite usar el pavimento existente como base.
Al hacer el diseño del pavimento se obtuvo un espesor de 100 milímetros de concreto hidráulico
sin dovelas debido a su espesor y la separación entre juntas. La categorización ambiental se hizo
mediante una solicitud a La Dirección General de Evaluación y Control Ambiental (DECA) que vela
por la obligatoria aplicación de la evaluación de impacto ambiental para todos los proyectos.
The purpose of the project was the geometric and structural design for the pavement restoration of the Boulevard Fuerzas Armadas in La Lima, Cortés through the use of whitetopping. The objective of this pavement restoration was to provide safe vehicular traffic that complies with all national codes. construction site for highways established. For the design of the whitetopping work, fundamental aspects were taken, such as a topographic study, soil quality, distances, angles and slopes of the boulevard, vehicular traffic and measurement of existing pavement damage in order to comply with all established quality standards. The methodology used is quantitative, because the values of the domain of variation are counted and measured. The design of the vertical and horizontal alignment was maintained respecting the original design of the road, except for small changes in the slopes, always respecting the maximum and minimum values allowed by the AASHTO standard. The rigid pavement was designed for a period of 10 years and the average CBR value was 34 and a reaction modulus of 108 mpa/m, which allows the existing pavement to be used as a base. When designing the pavement, a thickness of 100 millimeters of hydraulic concrete was obtained without voussoirs due to its thickness and the separation between joints. The environmental categorization was made through a request to the General Directorate of Environmental Evaluation and Control (DECA) which ensures the mandatory application of the environmental impact assessment for all projects.
