Abstract

The evaluation of the roughness through the determination of the International Roughness Index (IR) by the MERLIN rugosimeter, is currently one of the most important receptive controls related to the quality of pavement finishing, which is reflected in the Level of comfort, safety and operating costs for users. The correct completion of pavements is of great importance for the comfort, safety and cost of operation of road users, a factor that in addition to having a great influence on the duration of these, has an impact on road maintenance costs. In the present investigation it is necessary to analyze the quality of the pavement by determining the surface regularity, which has to do with the vertical irregularities accumulated over a kilometer, with respect to a horizontal plane in a pavement. These are mainly due to two causes: the first, the construction procedure, and the second to the damage to the road itself by vehicular traffic. Sometimes such irregularities are a combination of both; For example, the different layers that constitute a pavement usually present affectations due to settlements or accommodations of the materials that constitute them, and are a function of the loads that circulate on the pavement. They can also have their origin in a deficient construction process.
