Beckman Deflection Instrument,Benkelman Deflection Beam,Pavement Resilient Modulus Tester

Pavement rebound deflection tester/Pavement Benkelman deflection danda

Kuyera chiyero:

(1) Iyi nzira yakanakira kuyera kudzokororwa kwekutenderera kweakasiyana siyana migwagwa uye mapavement kuti aongorore kutakura kwavo kwese kugona uye inogona kushandiswa mukugadzirwa kwepavement zvimiro.

(2) The rebound deflection value yeroadbed uye inochinjika pavement yakayerwa neiyi nzira inogona kushandiswa pakupa uye kupedzisa kugamuchira.

(3) The rebound deflection of the pavement yakayerwa nenzira iyi inogona kupa hwaro hwedhipatimendi rekuchengetedza mugwagwa mukuru kugadzira chirongwa chekugadzirisa mugwagwa.

(4) Kutsauka kweasphalt pavement kunoenderana neyakajairwa tembiricha ye20 ℃.Paunenge uchiyedza pane dzimwe tembiricha (pamusoro pehupamhi hwe20±2 ℃), kukosha kwekutsauka kweasphalt pavement ine ukobvu hunodarika 5cm kunofanirwa kugadziriswa nekupisa.
