In this case study, aggregates and asphalt cement oil (CAP) aged, coming from damaged and subsequently milled through analysis and testing laboratories pavement were analyzed according to each material corresponding to Brazilian Standards (NBR) used in the production of layers the deck, as regards the manufacture of the base and the asphalt coating. The measurement methods for the production of milled mixtures with residual asphalt pavement and their percentages with pure soil were also analyzed, the latter characterized as a low soil bearing capacity in order to achieve the best strength, providing a durability in the underlying layers and reuse of the same milled material for asphalt coating of these layers, with significant savings on their possible applications in future maintenance. Thus, one can avail this stuff to stabilize a soil that did not meet the necessary requirements of the regulatory standards for such purposes, and intuited to give due importance to the concern for environmental issues, which are being addressed particularly sharply in today, minimizing the degradation of deposits of sand and river beds in relation to the removal of boulder, thus decreasing logistics costs, transportation and acquisition of new ones. The experimental results of recycled asphalt mixture to 100% of the milled asphalt pavement waste, evaluated in this study were compared with the results obtained for conventional mixtures and indicated that such a mixture can be used as an alternative for coating urban roads , given the conditions required in regulations on this matter. The ground reference mixtures with milled asphalt pavement residue (RFA) were compatible with the demands of a pavement of heavy traffic volume mechanical behavior. The results were satisfactory, highlighting the positive use of the RFA for application in the base layers of urban pavements. It is noteworthy that studies on the use of this type of waste in pavement, are rare in the city of Manaus and this research adds an exploratory knowledge of their potential applicability. / Este trabalho teve como objetivo estudar a reutilização do resíduo fresado do pavimento asfáltico retirado nas manutenções de vias urbanas. Nesse processo de estudo, foram analisados os agregados e o cimento asfáltico de petróleo (CAP) envelhecido, oriundos de pavimento deteriorado e posteriormente fresado, através de análises e ensaios de laboratórios segundo as normas brasileiras (NBR) correspondentes a cada material aplicado na produção das camadas do pavimento, no que diz respeito à confecção de base e ao revestimento asfáltico. Também foram analisados os métodos de dosagem para a produção das misturas com o resíduo fresado de pavimento asfáltico e suas respectivas porcentagens com o solo puro, este último caracterizado como um solo de baixa capacidade de suporte, no intuito de alcançar a melhor resistência, proporcionando uma maior durabilidade nas camadas subjacentes e ao reaproveitamento do mesmo material fresado para o revestimento asfáltico dessas camadas, com uma economia significativa nas suas possíveis aplicações em manutenções futuras. Assim, pode-se aproveitar esse material para estabilizar um solo que não atendia os requisitos necessários exigidos pelas normas regulamentadoras para esses fins, e no intuído de dar a devida importância na preocupação com as questões ambientais, que estão sendo abordadas de forma bastante acentuada nos dias atuais, minimizando a degradação de jazidas de areia e leitos de rios no que tange à retirada de seixo rolado, diminuindo assim os custos de logística, transporte e a aquisição de novos agregados. Os resultados experimentais da mistura asfáltica reciclada a 100%, do resíduo fresado do pavimento asfáltico, avaliadas nessa pesquisa foram comparados com os resultados obtidos para misturas convencionais e indicaram que tal mistura pode ser usada como alternativa para revestimento de vias urbanas, atendendo os requisitos exigidos em normas referentes ao assunto. As misturas solo de referência com resíduo fresado do pavimento asfáltico (RFA) apresentaram um comportamento mecânico compatível com as exigências de um pavimento de volume de tráfego pesado. Os resultados obtidos foram satisfatórios, ressaltando o emprego positivo do RFA para aplicação em camadas de base de pavimentos urbanos. Ressalta-se que os estudos sobre a utilização desse tipo de resíduo em pavimentação, são raros na cidade de Manaus e essa pesquisa agrega um conhecimento exploratório do potencial de sua aplicabilidade.

In our country the state of the roads has changed for the better in the last 10 years, and is becoming aware that it is best to adequately maintain their appropriate maintenance road, to repair a collapsed road but still not running action enough to say that we are well on roads, as there are still many miles to try. According to the Ministry of Transport and Communications (MTC) of the 86.965 kilometers of roads that owns the country, 80 % are unpaved roads (69.549 kilometers), 16% paved (13,683 kilometers), while 4 % are roads gauge (3,734 miles). In this research work have the opportunity to evaluate and compare two projects in our country with this technology, beginning with the La Oroya - Chicrín - Huánuco – Tingo María - Dv.Tocache que corresponds to the central road of Peru , which connects the city of Lima with the central jungle of the country , to major urban centers such as Oroya, Cerro de Pasco, Chicrín , Huanuco , Tingo Maria and Pucallpa , so that has a significant heavy traffic , which is constant for all seasons and road Conococha - Yanacancha belonging to the National Road Network (Route 3N ) was found in the provinces of Ancash Bolognesi and Huari over 4000 m which was built between 1999 - 2000 from Lake Conococha to the turnoff to the town of Huallanca . After several studies evidenced that the road to La Oroya - Chicrín - Huánuco – Tingo María - Dv. Tocache was an advanced state of deterioration, which was not effected routine maintenance, long time, so it was urgent intervention to it, since it caused constant discomfort of carriers. Similarly launched in 2007 to process the call notice No.PR- 007032, for the preparation of the Final Study for Periodic Maintenance of Road Conococha - Yanacancha as it was suitable to perform maintenance failures that had not affect traffic.
