This research evaluates the structural condition of the flexible pavement of the Cusco-Sicuani highway Tinta-San Pedro section 2019, which presents superficial and structural failures in the flexible pavement, therefore a structural evaluation of the pavement was carried out, which allowed obtaining results of how is the pavement of the road. The population includes the PE 3S national highway that connects the province of Cusco and Sicuani, section: Tinta (Km 10 + 910 Km) - San Pedro (13 + 430 Km), section located in the districts of Tinta and San Pedro, Canchis province, Cusco department. The sample has sixteen (16) holes in the tread binder, then seven (7) CBR tests for base, seven (7) CBR tests for subbase, sixteen (16) samples for quantitative asphalt extraction, sixteen (16) samples for specific gravity bulk, eighty (80) sample units for PCI determination and two (2) roadside test pits to verify the thickness of the structural package. The sampling method used is non-probabilistic, this sampling is suitable for the type of evaluation due to the cost and ease of availability of the sample. Regarding the results, the following is verified, for the rolling surface, 10 failures of the 19 specified in the methodology were found, the most frequent failures are longitudinal and transverse cracks with 38.6% and 1735.07 m this affects the pavement more on this road, followed by crocodile skin faults with 26.5% of the total faults that exist on the road. The average Pavement Condition Index (PCI) is 30.69 rating “BAD”. As for the Marshall test, cores were extracted to determine the stability and Marshall flow, obtaining the average of the stabilities of the nuclei of 21 120 N since these values resist a constant load ratio, the average of the flow values is 9.40 mm being optimal and in relation to the percentages of asphalt, these are stable and meet the ranges of the Asphalt Institute. Regarding the average CBR of the base of 49.85% and the average of the sub base of 26.37%, they do not meet the minimum vehicle load capacity established in the highway manual and the Asphalt Institute Guide, which indicate a minimum value of 80 % for the base and a minimum of 40% for the sub base, through the vehicle count it was determined that the vehicles that transit more frequently are rural combis with 23.80% followed by cars with 15.34% of total vehicles. Using the number of equivalent axes of 10006.64, a minimum asphalt concrete thickness of 2.5 cm and a granular base of 10 cm was verified.
