*3.5. Abrasive Wear Test*

Table 4 presents the thickness reduction of ENS-15 after two specimens were subjected to abrasive wear tests at two running distances, 500 and 1000 m.



For artificial stones to be applied for civil construction, there are no requirements, standards, or limits to thickness reduction in abrasive wear tests. Chiodi Filho and Rodrigues [30] proposed technological parameters for the use of artificial stones in pavements. The authors recommended that pavements with low traffic should display wear thickness reduction lower than 6 mm, medium traffic should be lower than 3 mm, and heavy traffic lower than 1.5 mm. Based on the described parameters, the novel ENS-15 (Table 4) can be used for medium traffic pavement, since it presented a thickness reduction below 3 mm on the 1000 m track.
