Mejoramiento del trazado geométrico y diseño de la estructura del pavimento, desde el sector Guadalupe al puente de Patate San Javier, del cantón Patate, provincia de Tungurahua

Abstract

The road infrastructure that connects the Guadalupe sector with the "Los Sauces" bridge in Patate San Javier has problems in different sections of its geometric design, especially in curves, because they do not comply with the minimum widths required by heavy transport users, consequently, they are delayed in taking these curve s, hindering the passage and delaying the other occupants of the road; therefore, modifications were made to the current layout, ensuring safety, comfort and efficiency when driving. For the completion of the project, a topographic survey of the road was carried out to determine the current conditions of the terrain. A traffic study was carried out by means of a manual vehicle count in order to determine the type of road according to t he future TPDA obtained, resulting in a Class II Road according to the MTOP and a two lane C1 road according to the NEVI 12. In addition, soil samples were taken for each kilometer and analyzed in the laboratory for: granulometry, moisture content, Atterbe rg Limits, Modified Proctor Type B and CBR according to the AASHTO standard; once the soil analysis was completed, the pavement structure was designed according to the parameters established by the AASHTO 93 standard. Finally, the new geometric layout of the road was developed with its respective minor works of art, work volumes were quantified, and a reference budget was estimated by analyzing unit prices with values updated by the construction market.
