SPJ kata 'screened crushed hard rock', dan mesti comply dengan physical and mechanical quality requirements (seperti LA abrasion value, flakiness index etc). Tidak disebut mesti guna granite sahaja. Apa jua aggregate boleh dipakai asalkan ia comply dengan quality requirements. Namun, SPJ ada nyatakan secara khusus 'limestone aggregate shall not be permitted for use in wearing course'.
