In　order　to　investigate　the　influence　of　basalt　fibers　(BFs)　on　the　mechanical　performance　of　recycled　aggregate　concrete　(RAC),　some　groups　of　RAC　specimens　were　first　tested　involving　different　types　of　fibers　such　as　carbon　fibers,　steel　fibers,　polypropylene　fibers　and　hybrid　fibers.　The　main　four　indices　for　the　investigation　consisted　of　cube　compressive　strengths,　axial　compressive　strengths,　splitting　tensile　strengths　and　Young＇s　modulus.　The　effects　of　fiber　volume　fractions　on　the　RAC　slumps　were　also　discussed.　Meanwhile,　the　mechanical　properties　and　failure　modes　of　the　BF-reinforced　RAC　were　compared　with　those　of　other　fiber-reinforced　RAC　and　common　concrete　(CC).　Subsequently　the　optimal　volume　fractions　of　BFs　were　explored　for　different　mechanical　properties　within　the　volume　fraction　range　of　0-0.2%.　The　back　propagation　neural　networks　were　further　applied　to　predict　and　validate　the　optimal　BF　fractions.　Lastly,　the　general　strength　formulas,　as　well　as　the　elastic　modulus　formula,　for　BF-reinforced　RAC　were　deducted　based　on　the　specimen　test　results.　It　is　found　that　the　addition　of　fibers　may　improve　the　failure　modes　of　RAC　and　different　fibers　present　positive　or　negative　effects　on　the　mechanical　properties.　The　optimal　volume　fractions　of　BF　with　respect　to　the　four　mechanical　indices　are　0.1%,　0.15%,　0.1%　and　0.2%　respectively.　The　proposed　strength　and　elastic　modulus　formulas　of　BF-reinforced　RAC　provide　satisfactory　predictions　with　the　test　results　and　thus　can　be　used　as　a　reference　in　practice.
