Isixhobo sokuDeflection sikaBeckman, iBenkelman Deflection Beam, iPavement Resilient Modulus Tester

I-Pavement rebound tester ephambukayo/iPavement ye-Benkelman yokutyekisa umqadi

Uluhlu lokulinganisa:

(1) Le ndlela ikulungele ukulinganisa ukuchezuka okubuyela umva kwiibhedi zendlela ezahlukeneyo kunye neepavumente ukuvavanya ukuthwala kwazo zonke kwaye zinokusetyenziswa kuyilo lwezakhiwo zepavumente.

(2) Ixabiso lokuphambuka kwi-rebound ye-roadbed kunye ne-flexible pavement elinganiswe ngale ndlela ingasetyenziselwa ukunikezelwa kunye nokwamkelwa kokugqiba.

(3) Ujikelo lokubuyela umva kwendlela yabahambi ngeenyawo elinganiswe yile ndlela inokubonelela ngesiseko kwisebe lolawulo lokulungiswa kohola wendlela ukwenza isicwangciso solondolozo lwendlela.

(4) Ukuphambukiswa kwendlela ye-asphalt isekelwe kubushushu obuqhelekileyo obuyi-20℃.Xa kuvavanywa kwamanye amaqondo obushushu (ngaphezu koluhlu lwe-20±2℃), ixabiso lokuphambuka kwendlela ye-asphalt enobunzima obungaphezulu kwe-5cm kufuneka ilungiswe bubushushu.

Izinto eziphathekayo: ingxubevange yealuminiyam, ubude: 3.6m, 5.4m, 7.2m
