La caracterización geotécnica de materiales granulares gruesos tales como suelos de granulometría muy gruesa, enrocados, lastres de mina y otros materiales semejantes, es uno de los temas clave, pero menos abordados y estudiados en ingeniería geotécnica. Aunque existen algunas normas y cierta práctica geotécnica aceptada, no hay normativa de escalamiento de tamaño, lo cual representa un punto crítico en el avance de la ingeniería (diseño de detalle) en estructuras grandes que involucran este tipo de materiales. Varias técnicas de escalamiento de tamaño están disponibles, las cuales tienen ventajas y desventajas. Entre estas técnicas, el método de granulometría paralela (también conocido como granulometrías homotéticas), es uno de los usados actualmente en la práctica por más de 50 años, pero sorpresivamente solo unos pocos estudios han corroborado su capacidad y usando materiales específicos. Este trabajo examina una base de datos detallada abarcando el desarrollo de este método desde sus primeros usos hasta ahora. La aplicación de este método se analiza basándose principalmente en el ángulo de fricción interna máximo y el parámetro de rotura de partículas de Marsal (Bg).
