Umvavanyi wePavement eGuquka kwiPavement 5.4m iBeckman Beam yePavement eGuquka uMvavanyi uBuyisela uKutyeka 3.6 7.2m

Isixhobo sokuvavanya imodyuli yePavement (iBenkelman Beam)

Indlela yeBeckman beam yindlela efanelekileyo yokulinganisa ixabiso le-elastic deflection yomgangatho wendlela phantsi kokulayisha okumileyo okanye ukulayisha okucothayo kakhulu, kwaye inokubonisa kakuhle amandla onke omgangatho wendlela.

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.
