Description
Se efectuó el diseño geométrico y estructural de pavimento y drenaje pluvial de la segunda
calle y tercera avenida en Pueblo Nuevo, Puerto Cortés con el objetivo del impulso de la
ampliación de la red vial bajo el Plan de Desarrollo Municipal. Se tomaron en cuenta variables
fundamentales como la topografía del sitio, propiedades del suelo bajo normativa AASHTO,
diseño geométrico en función de las características físicas del terreno, diseño estructural bajo
el método PCA-84 según el análisis del tránsito vehicular y el diseño del drenaje pluvial. Se
diseñó geométricamente una calzada de 7.00m y dos carriles opuestos con un ancho de carril
de 3.50m. La pendiente mínima utilizada fue de 0.21% y la máxima de 0.50%, las bajas
pendientes se presentaron debido a la existencia de casas habitadas a lo largo de todas las
calles y avenidas del barrio, la prevención de mayores volúmenes de corte y el funcionamiento
del drenaje pluvial. El pavimento de concreto simple con varillas de transferencia se diseñó con
una estructura de subbase con espesor de 10cm y una losa de concreto hidráulico con 18cm
de espesor con una resistencia a la compresión de 4000 PSI. Los canales abiertos se diseñaron
con un ancho de 0.60m, altura de 0.50m y paredes del canal con bloque de 0.15m, con una
pendiente del 1%.
The geometric and structural design of the pavement and storm drainage of the second street and third avenue in Pueblo Nuevo, Puerto Cortés was carried out with the objective of promoting the expansion of the road network under the Municipal Development Plan. Fundamental variables such as the topography of the site, soil properties under AASHTO regulations, geometric design based on the physical characteristics of the terrain, structural design under the PCA-84 method according to the analysis of vehicular traffic and the design of storm drainage were considered. A 7.00m roadway and two opposing lanes with a lane width of 3.50m were geometrically designed. The minimum slope used was 0.21% and the maximum of 0.50%, the pending drops occurred due to the existence of inhabited houses along all the streets and avenues of the neighborhood, the prevention of greater cutting volumes and the operation of the storm drain. The simple concrete pavement with transfer rods was designed with a 10cm-thick subbase structure and a 18cm-thick hydraulic concrete slab with a compressive strength of 4000 PSI. The open channels were designed with a width of 0.60m, a height of 0.50m and channel walls with concrete blocks of 0.15m, with a slope of 1%.
