Técnicas de conservação e restauração de pavimentos flexíveis

Abstract

Over time, asphalt paving loses quality on the running surface, requiring intervention with an adequate maintenance and conservation solution to recover its state of usefulness. Throughout its life cycle, a road pavement has weather and traffic actions, which contribute to a progressive decrease in the quality of the mechanical and functional characteristics of the materials. Usually these requests contribute to pathologies, which affect road traffic safety. The objective of this work is to demonstrate the importance of management in the maintenance and conservation of the asphalt pavement through a survey with a concessionaire responsible for the maintenance and conservation of the Raposo Tavares Highway in SP. The most common pathological manifestations on flexible pavements and the appropriate restoration measures employed by the highway administrator were recorded, and it can be observed that it is possible to carry out the appropriate interventions for each type of irregularity on the pavement as long as there is a team prepared to carry out each stage, in addition to equipment in good condition and prior analysis of the characteristics of the stretch and vehicle traffic. It is considered that technical knowledge about pathological manifestations in flexible pavements and efficient and responsible corrective activities can offer a longer useful life to paved access roads, bringing greater comfort, safety and economy to users, in addition to avoiding ineffective actions, bringing costs and rework, contributing to poor traffic conditions.
