Caracterización de tránsito vehicular basado al método aashto de espectros de carga en Avenida 25 de Junio ciudad de Machala

Abstract

The arterial corridor Trunk of the E25 Coast or also known as Avenue 25 of June is the main axis of access of the city of Machala, it extends from the northern circumvallation avenue sector school Machala and consists of an extension of 9.5 kilometers. Considered as the axis of entrance to the city the sector Monument El Bananero to the exchanger The change being the section of an analyst in the following work. In order to obtain an adequate structural design of the pavement, it is necessary to know the effects produced by the traffic loads. For this reason, it is necessary to predict which is the number of vehicles that circulate on the road, in addition to identifying the types of axles and what is the load capacity of the cars that move. The following case analysis work is related to the access to the city of Machala, as the route and mentioned, classifying and analyzing the vehicles by type and own load that can do it, in addition to the vehicles that carry loads for this avenue . The content of vehicles is a fundamental task in the realization of traffic gauges, both for the design of a road and the optimization of urban traffic. The counting and classification based on the number of axes, this is possible to do with various techniques and procedures which is divided into four groups. · Counting Manual · Sensor counting · Counting with magnetic sensors · Counting with artificial vision. On Avenida 25 de Junio, this content is sold manually according to the regulations established for the Ministry of Transport and Public Works (MTOP), where the specific characteristics of the different types of cars that circulate on the roads of Ecuador are detailed. Classifying them by type of vehicle and each one with the different loads exerted by their axes on the tracks. This document presents load spectra per axis, which serves to know what the traffic condition of Avenida 25 de Junio ​​is, in order to design and better the state of the road. With the data obtained from the gauging carried out from June 11 to 15 from 7 in the morning until 6 in the afternoon, outside the Technical University of Machala, the different loading spectra could be made. The data gave as a result that vehicles entering the city of Machala 11% pass through the design lane and of this percentage they dropped 22% and 23% are within 18 and 25 tons. The results obtained in the load spectrum for the exit lane of the City of Machala detailed that 12% circulated in the design lane as 32 and 39% were vehicles of 18 and 25 tons. This work is carried out with the objective of obtaining the load spectrum generated by the vehicles that travel along this avenue, which help in the structural design, maintenance and power increase the reliability of the pavement.
