    Through this technical project, the proposal of the conservation plan of the structure of Ambato-Pillaro’s rolling layer in the abscissa’s section from 0+000 km to the 4+000 in Yacupamba area of Izamba parish in Ambato city of Tungurahua’s province was done. Thanks to Dron uses a suitable data register was possible to do in order to get a georeferenced survey for the road’s digitization. Other elements which were helpful for the road’s abscissa were paint and tape measure. During a week from monday to sunday with an interval of 12 hours, vehicle traffic was counted and as a result of this a future TPDA value of 11124 vehicles per day was calculated. For this reason, this road is classified as an AV1 Multilane Highway To do a study of soils, 8 calicatas were done in order to determine the CBR whose average value is 22.7 porcent, this means that the subrassant’s behavior is excellent. Through the use of the Benkelman beam, the deflections presented by the pavement surface were measured every 200 meters. Furthermore, the visual inspection was made along the road section and different faults were found. Thanks to this, the Pavement Condition Index (PCI) was obtained with a high rating score due to it the road only needs routine maintenance.

    The present experimental work and was carried out with the purpose of establishing a method of conservation of the tread layer of the Ambato - Tisaleo road in the section 3 + 200 to 6 + 400 of the province of Tungurahua. A georeferenced survey was carried out every 20 meters of the road under study using a Satellite Receiver (GPS), generating a digitization of the road. To determine the vehicle traffic study, a vehicle count was carried out manually, 7 days a week from 06:00 a.m. until 6:00 p.m. thus generating future traffic of 10,917 vehicles / day. Through the Benkelman Beam test, the behavior of the pavement structure and the subgrade was known through deflections, establishing that it generates type I deflections. With the PCI test, which establishes that samples should be taken by units in intervals allowing to know the road failures with their respective severity. Four pits were made along the road, by means of which it was possible to determine the optimal moisture content and the maximum dry density through the modified Proctor, the liquid index and the plasticity index with the Limits of Attemberg and the CBR of the ground with its respective test.

    The work presents a conservation model for the current state of the structure of the wearing course of the Ambato-Tisaleo road in the Santa Rosa - Juan Benigno Vela sector in the section of the 6+400 to 9+600 abscissa, for which a series of tests and studies were carried out to obtain an objective and realistic evaluation. The georeferenced survey of the section under study was carried out by recording coordinates through a GPS satellite receiver every 20 meters, data that allowed the representation and location of the track in a digital way. The current and future traffic of the road was determined by counting vehicles during one week, exposing the road as a multi-lane AV1 route. A visual inspection was carried out applying the PCI method, reducing to 15 sampling units to be studied, resulting in a PCI of 82.30 percent, qualifying the road as in good condition. Obtaining the deflections of the wearing course with the Benkelman beam, in 17 different points of the track, resolving that the track generates type I deflections, which means that the structure of the pavement and its subgrade present stable conditions. Four open pits were made, to determine the behaviour of its subgrade, mainly its CBR value which was a value of 10,4 which this result determines the soil in a range from fair to good for subgrade.

    The present technical work proposes the implementation of a road conservation model, because the Ambato-Tisaleo road is a communication link between these two cantons and it does not have a road maintenance plan that serves to postpone the useful life of the pavement structure. For the present work a visual evaluation of the surface of the structure was carried out, this method is known as Pavement Condition Index (PCI), which allows to evaluate the type of failure, classify it according to the level of severity and determine in what state is the surface layer of the flexible pavement. The Benkelman Beam being a non-destructive test, which by means of the deflections given by a team dial, allows to know the behavior of the pavement and the subgrade. The Ambato-Tisaleo route in the section given by abscissa 0 + 000 to abscissa 3 + 200 consists of two types of deflections which are: Type I and Type III. When carrying out 4 open pit wells, 50 kg of soil was extracted to perform the following tests: Atterberg Limits, Granulometry, Modified Proctor Type B and CBR, these tests served to classify the soil type and determine that the soil is in a range Good to Regular for subgrade use. When using the methodology already described above, it was concluded that periodic maintenance should be performed from abscissa 0 + 000 to abscissa 1 + 600, while from abscissa 1 + 600 to abscissa 3 + 200 a routine maintenance should be performed, this is due to the current state of it.

    In the present experimental work, a plan for the conservation of the structure of the tread layer of the Patate - Píllaro road is proposed in its 3,920 m of study. A georeferenced survey of the road section under study was carried out, in which an abscissa was considered every 20 m, data were recorded with the GPS satellite receiver, obtaining an amount of 590 points with their respective coordinates, data that allowed the digital model to be made of the track. The vehicular traffic that circulates on the road under study was analyzed, analysis that allowed classifying the road in class II and collector because it receives the traffic of the neighborhood roads. Through the application of the PCI methodology, a section with 17 sampling units was evaluated, whose average value of PCI was 77.82, which corresponds to a very good road classification, which implies maintenance on the road surface. The measurement of the deflections was carried out with the Benkelman beam, for which 20 stations were determined every 200 m along the track, resulting in a type I deflection, which means a good structural behavior of the pavement and the subgrade. 4 openwork calicates were made to perform the tests and determine the type of soil. Edge, gravel and sand type soil has a CBR greater than 30 percent which is used as a subbase, while fine sand and silty soil materials are used as a subgrade.

    Initially a road inventory was made where the length, width of the road, ditches, water passages and sections of the current road were found. In addition, the existence of an initial section from abscissa 0+000 to abscissa 2+100 and a continuous section from abscissa 2+100 to abscissa 4+170 were identified. A georederencing was perdormed in UTM coordinates WGS 84 17 S. It was also necessary to perform a manual vehicle count over a period of one week for twelve hours to determine the equivalent axes to be used for a subsequent reinforcement or pavement design. As information collection methods are soil studies at each kilometer to subsequently perform laboratory tests such as: Granulometry, Atterberg Limits, Compaction and Modified Proctor resulting in the mechanical properties of the materials that make up the pavement structure. For the evaluations of the condition of the pavement, the Benkelman Beam is identified and the Pavement Condition Index (PCI) method, these tests identify the quality and severity of the faults located in the tread layer in a visual and non-destructive way. Analyzing the results that are on the road is in very good condition and mostly the road that needs periodic maintenance and rehabilitation is deduced according to the current regulations of the Ministry of Transportation and Public Works (MTOP), American State Highway Association Standard and Transportation (AASHTO), American Materials Testing Association (ASTM) and National Institute for Standardization (INEN).
