This paper presents a methodology for the rockfall hazard assessment along roads. The main contribution of this work is to measure and analyze the marks that have been printed on the asphalt pavement, product of previous impacts of rock blocks, and take this information to assess the historical threat , once consolidated the historic threat, from the marks study, we obtained the current threat, using conventional techniques of rock mechanics and finally by integrating the two sources of information, obtain a more accurately knowledge of the magnitude and location of the threat along the road section under study. As a case study is presented the area known as "La Volcana", located on K 16+300 of the Guillermo Gaviria Correa road, which connects the city of Medellín with the municipality of Santa Fé de Antioquia in Antioquia Department - Colombia.
