The pavement can be defined with a semi-infinite multilayer structure whose function is to transmit the stresses caused by traffic on the foundation ground (subgrade), besides providing the users with good conditions of comfort and safety. We know that death in traffic is responsible for generating large expenses for the government, so road safety is crucial for the country's development. The surface texture of the pavements affects several aspects related to the comfort and safety of users, especially the effect of tire / pavement adhesion and hydroplaning. The present study evaluates the main characteristics of the pavement macrostructure along the NS-15 Avenue layout between Juscelino Kubitscheck and LO-08 avenues and verifies that these values ​​are in accordance with the ASTM E 965-96 and ASTM E 2380 regulatory standards. To this end, the Sandblot and Drainability tests were performed according to the reference values ​​in Brazil.
