EVALUATION OF PAVEMENT IRREGULARITIES USING A MOBILE APPLICATION

Abstract

The research evaluated the surface conditions of the TA-642 road in Tacna, Peru, using the TotalPave application on smartphones to measure the roughness and passability of the pavement. Descriptive-exploratory analysis methods with a quantitative approach were employed, collecting data every 400 meters over a distance of 12.8 km at speeds of 80 km/h, utilizing the sensors and GPS of the mobile device. The results showed an International Roughness Index (IRI) of 3.78 m/km and a passability score of 2.58, both classified as "Regular" according to Peruvian standards. These values indicate that the road has surface irregularities that may cause discomfort and damage to vehicles during transit. The study confirms the potential of TotalPave to effectively assess pavement roughness in a versatile, economical, and reliable manner compared to traditional methods. This mobile application uses smartphone sensors to measure the vehicle's vertical acceleration and accurately estimate the IRI.In conclusion, the use of mobile applications enables the assessment of road conditions and the planning of timely maintenance interventions, optimizing resources and improving transportation quality. This is particularly relevant in countries with budget constraints for road construction and maintenance.
