Kunomehluko omncane esakhiweni sokusebenza samaloli okuvala amatshe e-asphalt gravel synchronous emakethe, kodwa kuzoba nomehluko othile esakhiweni semishini. Amaloli ahlanganisa i-asphalt gravel synchronous sealing asetshenziselwa ikakhulukazi izindawo zomgwaqo, ukuvikela amanzi kwebhuloho, kanye nezingqimba eziphansi zokuvala. Inqubo yokuvala amatshe. Le mishini ibona ukuvumelanisa kokusakazwa kwe-asphalt binder kanye nokusabalalisa kwamatshe, ukuze i-asphalt binder namatshe abe nokuxhumana okugcwele kwendawo ngesikhathi esifushane futhi afinyelele ukunamathela okuphezulu phakathi kwawo. Imishini ifaneleka ngokukhethekile ukusabalalisa izibophezelo ze-asphalt ezidinga ukusetshenziswa kwe-asphalt eguquliwe noma i-asphalt yenjoloba. Umsebenzi ophelele uwukuqedela ukusabalala kwetiyela kanye nokusabalalisa amatshe ngasikhathi sinye.
Iloli le-asphalt gravel synchronous sealing iloli limunca itiyela ethangini letiyela ngokusebenzisa iphampu yetiyela, bese liyifafaza liphuma entweni yokusabalalisa itiyela ngochungechunge lwamavalvu namapayipi; ngesikhathi esifanayo, uhlelo lokusabalalisa amatshe lusebenza ngokuhambisanayo. Isilayishi silayisha isamba emgqonyeni weloli elivalwayo kusenesikhathi. Ngesikhathi sokusebenza, i-hydraulic motor ishayela amabhande okuhambisa (amabili) ukuthumela amatshe ku-hopper esakazayo. Uhlelo lwe-pneumatic lulawula isilinda ukuvula umnyango wezinto ezibonakalayo, futhi ama-rollers asakazayo aqhutshwa yi-hydraulic motor. Ngaphansi kwe-drive, ama-aggregate agelezayo ayahlukaniswa futhi aphonswe emgodini wokuqondisa. Itshe lisakazwa ngokulinganayo endaweni egandaywe yitiyela ngokusebenzisa umkhombe womhlahlandlela, ngaleyo ndlela kuqedelwa umsebenzi wokuvala ohambisanayo wetshe le-asphalt.
Iphampu ye-hydraulic ishayela i-hydraulic motor ukuthi ijikeleze, okushayela isithuthi sebhande ukuthi sisebenze, sithuthe igravel ohlelweni lokusabalalisa amatshe. Umnyango wezinto ezibonakalayo uvulwa ngesistimu ye-pneumatic, futhi i-gravel isakazwa ngaphansi kwesenzo sesisindo setshe kanye nokujikeleza kwe-roller yokusabalalisa. Kunezinzwa zezinga lezinto ezimbili ohlelweni lokusabalalisa. Isistimu yokulawula ye-elekthronikhi isebenzisa lezi zinzwa ezimbili ukuqapha izinga lempahla ku-hopper eyi-axiliary futhi ilawula ukuthi ama-valve amabili e-solenoid anamandla, ngaleyo ndlela ilawula ukuthi ingabe injini edlulisayo iyasebenza futhi ibona ukuthunyelwa kwe-aggregate. Ukulawula kwesikhathi sangempela. Ngesikhathi sokulungisa iphutha, isivinini se-motor feed silungiswa ngokulawula usayizi wokuvuleka kwe-throttle valve. Ngokuvamile, isivinini sokuqala senjini sisethelwe cishe ku-260r·min-1. Ijubane lemoto lingashintshwa ngokuya ngezimo zangempela zokusebenza ukuze kuhlangatshezwane nezidingo zokwakha.
Umgomo wawo uhambisana nomgomo wohlelo lwe-hydraulic olusabalalisa amatshe. Ijubane lokusabalalisa i-roller motor lilawulwa ngokulungisa i-valve ye-throttle, futhi ukuqala nokumiswa kwe-roller yokusabalalisa kubonakala ngokulawula ukuthi i-valve ye-solenoid inamandla noma cha.

Iqhaza elibalulekile lobuchwepheshe bokuvalwa kwe-slurry ekulungisweni komgwaqo omkhulu
