Isihloli sokuchezuka kwe-Pavement 5.4m I-Beckman Beam Pavement Deflection Tester Rebound Deflection Tester 3.6 7.2m

Imishini yokuhlola i-Pavement resilient modulus(Benkelman Beam)

Indlela ye-Beckman beam iyindlela efanelekile yokulinganisa inani lokuchezuka elinwebekayo lendawo yomgwaqo ngaphansi kokulayisha okumile noma ukulayisha okuhamba kancane kakhulu, futhi ingabonisa kahle wonke amandla omgwaqo.

Ibanga lokulinganisa:

(1) Le ndlela ifaneleka ukulinganisa ukuchezuka kokubuyela emuva kwemibhede yomgwaqo ehlukahlukene kanye ne-pavement ukuze kuhlolwe umthamo wazo wonke wokuthwala futhi ingasetshenziswa ekwakhiweni kwezakhiwo zomgandaya.

(2) Inani lokuchezuka elibuyela emuva lombhede womgwaqo kanye nendawo egandaywayo eguquguqukayo elinganiswa ngale ndlela ingasetshenziselwa ukunikezela nokwamukela ukuqedwa.

(3) Ukuchezukiswa kokubuyela emuva komgandayo okalwa ngale ndlela kunganikeza isisekelo somnyango olawula ukugcinwa komgwaqo omkhulu ukuze wenze uhlelo lokulungisa umgwaqo.

(4) Ukuchezuka kokugandaywa kwetiyela kusekelwe ekushiseni okujwayelekile okungu-20℃.Lapho kuhlolwa kwamanye amazinga okushisa (ngaphezu kwebanga elingu-20±2℃), inani lokuchezuka kwendlela egandaywe yitiyela enogqinsi olungaphezu kuka-5cm kufanele lilungiswe izinga lokushisa.
