Análise da modalidade empregue para as obras de emergência conducentes à reposição da transitabilidade na estrada R807, troço Coca-Cola/Matola Gare

Abstract

One of the biggest problems facing Mozambique is related to the level of quality of roads. It is well known that roads are infrastructures that the development of other sectors of the economy in the country. Therefore, the their good execution and proper maintenance is also an important requirement for the development of for the development of existing and future economic infrastructure. Often, the problems encountered on roads are caused by deficient of rainwater drainage systems. In many cases where drainage systems In many cases where drainage systems are in place, other problems associated In many cases where drainage systems do exist, other problems associated with siltation are experienced at the same time. At In many cases the biggest problem may not be associated with the quality of the materials materials used or even with the dimensioning of the pavement, but rather with the the routing of rainwater. This paper presents an analysis of the modality used for the Emergency works leading to the restoration of trafficability on the road R807, section Coca Cola/Matola Gare, with an extension of 12.5 km. The improvement solution adopted has The main goal of the adopted improvement solution is to improve road transitability conditions reducing traffic congestion, travel time and vehicle operating costs and and increasing the safety and comfort of the road. The materialisation of this work begins with a review of the bibliography, where the road classifications in Mozambique are the classification of roads in Mozambique, the types of pavements, their characteristics and characteristics and types of materials used in road pavements, including the materials used in Mozambique. the materials used in Mozambique. The methods of methods for pavement design used in Mozambique, the types of defects in pavements and the defects in pavements and the methodology for the study of storm water drainage are also presented. Next, the report of the internship carried out in the institution ANE Maputo Delegation, where the activities of a construction site were monitored. In In the report, the phases of the implementation process of the previously planned maintenance interventions maintenance interventions previously planned and an analysis is made of the improvement solution taking into the quality of the materials allocated and the existing material, and the aspects aspects related to rainwater drainage.
