Ballast treated with asphalt emulsion, Megarok and San Jose. AASTHO standards

Abstract:

The deposits that are currently used in Portoviejo are Megarok and San José, which are located in the Picoazá parish of the Portoviejo canton. In very ancient periods the roads were traced by the passage of the animals, one of the main drivers of The construction of roads and aqueducts was the Roman Empire. The most important legacy that the Roman civilization left us was Law and public works. The roads are the busiest areas at present, where more people are traveling daily, in Portoviejo there are different quarries that could be used in the construction of these roads, but for this, you need to make studies that allow knowing the characteristics of the material [1]. At present, asphalt mixtures are already being used in the construction of road surfaces, either in rolling layers or in lower layers and their function is to provide a comfortable, safe and economical bearing surface for the users of the roads, providing the circulation of the vehicles, apart from sufficiently transferring the loads due to the traffic to the Esplanade so that they are supported by it [2]. In recent years in Ecuador there has been significant growth in terms of infrastructure, especially in road infrastructure, which is why it is necessary to have strategies to keep the communication channels and keep them operational in optimal conditions of functionality, since the investment represented by the construction of a road is very high and it is expected that it will meet its useful life for which it was designed, the technology most used in the maintenance and construction of pavements [3]. In the province of Manabí, especially Portoviejo in its territory has different quarries to extract material for the …
