Lapho isikhathi sifika sokuba usomabhizinisi enze isinqumo sakhe sokuthenga isitshalo setiyela, angase akushiyele kubahlinzeki bempahla ukuze bamsize banqume indlela engcono kakhulu yokuhlela nokumisa. Njengomholi wezobuchwepheshe wezitshalo zokuxuba i-asphalt, singanikeza amakhasimende ethu izixazululo zomshini weselula wokwakhiwa komgwaqo nokulungiswa komgwaqo, kanye nokukhiqizwa kwe-asphalt.

Ku-batch mix izitshalo ze-asphalt isisindo se-aggregates sibhekwa ngemva kokoma, ngaphambi kokuba zifakwe ku-mixer. Ngakho-ke, ukukala ku-hopper yesisindo akuthonywa umswakama noma izici eziguquguqukayo, njengezimo zezulu ezishintshayo.

Ezitshalweni ze-asphalt ze-batch, i-mixer enezingalo ezimbili nama-paddles isho ikhwalithi yokuxuba ngokungangabazeki ukuthi ingcono uma iqhathaniswa nezitshalo eziqhubekayo ngoba iphoqelelwe. Lesi sici sibaluleke kakhulu uma usebenzisana ‘nemikhiqizo ekhethekile’ (i-asphalt enembobo, i-splitmastik, okuqukethwe okuphezulu kwe-RAP, njll), edinga izinga eliphezulu lokulawula ikhwalithi. Ukwengeza, ngezindlela ‘zokuxuba ngempoqo’, isikhathi sokuxuba singanwetshwa noma sifinyezwe futhi ngalokho izinga lokuxuba lingahlukahluka, kuye ngohlobo lwezinto ezikhiqizwayo. Ngakolunye uhlangothi, ezitshalweni eziqhubekayo ubude besenzo sokuxuba kufanele buhlale buhlala njalo.

Izitshalo zokuxuba iqoqo le-asphalt le-Sinoroader aziqhubeki zixuba izingxenye ezikalwe ngokunembile (amaminerali, itiyela, isigcwalisi) zengxube yetiyela ngamaqoqo njengokusho kweresiphi kumxube wetiyela. Le nqubo iguquguquka kakhulu ngoba iresiphi yengxube ingashintshwa ngenqwaba ngayinye. Ngaphezu kwalokho, izinga eliphezulu lokuxuba lingafinyelelwa ngenxa yobuningi obunembe kakhulu kanye nezikhathi zokuxutshwa eziguquliwe noma imijikelezo yokuxuba.

Itiyela elishisayo kufanele libe nezinga lokushisa lokucubungula okungenani elingu-60 °C. Njengoba ingxube ye-asphaltic akufanele iphole endleleni esuka esitshalweni se-asphalt eya endaweni oya kuyo, iketango lezokuthutha elihambisanayo eliyinkimbinkimbi elinezimoto ezinenhloso ekhethekile liyadingeka. Ukusetshenziswa kwezimoto ezinenhloso ekhethekile kunomthelela wokuthi itiyela elishisayo ngokuvamile alisebenzi ngokwezomnotho futhi alikwazi ukulungiswa okuncane.

ngobuchwepheshe beSinoroader, wonke amakhasimende angathola isisombululo esifanele ngendawo yawo, ngokuya ngezidingo nezimo ezithile.
