Emhlabeni wengqalasizinda, ukusungulwa kobuchwepheshe be-asphalt akuzona izindaba ezihamba phambili ngaso sonke isikhathi, nokho izinkampani ezinjengoMartin Marietta zicindezela buthule imingcele futhi zishintsha ubuso bokwakhiwa komgwaqo. Ngenkathi ukulandisa okuvamile kuvame ukuzungeza emikhakheni yezobuchwepheshe ebonakalayo kakhudlwana, ukusungulwa kwe-asphalt kubaluleke kakhulu. U-Martin Marietta, owakha phezu kwesipiliyoni samashumi eminyaka, uhola intuthuko engase ingashintshi nje kuphela indlela imigwaqo eyakhiwa ngayo kodwa nendlela esebenza ngayo ngokuhamba kwesikhathi.
Ukuqonda Okuyisisekelo
Umuntu angase acabange ukuthi itiyela liyingxube nje elula yama-aggregate ne-binder, kodwa iqiniso liyinkimbinkimbi kakhulu. U-Martin Marietta, ofana noontanga bemboni u-Taian Yueshou Mixing Equipment Co., Ltd., uyazi ukuthi ukuqanjwa kabusha kulo mkhakha kuvame ukubandakanya ukucwenga yonke ingxenye ukuze kuthuthukiswe ukusebenza kahle. Njengoba nje uTaian Yueshou asebenzise indawo yakhe enkulu nezinsiza eChina ukuze athuthukise ubuchwepheshe bemishini yokuxutshwa, uMartin Marietta usebenzisa ucwaningo olunzulu ezinqubweni zabo zokukhiqiza itiyela.
Isibonelo, bagxile ekuthuthukiseni ukuqina nokusimama. Lokhu akubandakanyi izinto zokwakha kuphela kodwa nezinqubo—ukulawula izinga lokushisa ngesikhathi sokuxutshwa, inhlanganisela enembile yamaqoqo, nezindlela ezintsha zokugaywa kabusha.
Isicelo esisodwa somhlaba wangempela lokhu okungabonakala kusekuthuthukisweni kwetiyela lengxube efudumele. Lolu hlobo lwe-asphalt lukhiqizwa emazingeni okushisa aphansi uma kuqhathaniswa ne-asphalt yendabuko eshisayo, ukonga amandla nokunciphisa ukukhishwa. Yilezi zinhlobo zemininingwane ezihlukanisa ngempela abaholi bemboni.
Ukusebenzisa Amasu Okugaya Kabusha
Ukusetshenziswa kwezinto ezigaywe kabusha ku-asphalt akukusha, kodwa u-Martin Marietta uqhubekisele phambili lokhu ngokuthuthukisa ikhwalithi namaphesenti wokuqukethwe okugaywe kabusha ngaphandle kokuphazamisa ubuqotho bezinto ezibonakalayo. Amasu abawasebenzisayo ahlanganisa ukusebenzisa i-asphalt pavement (RAP) kanye nokuhlanganisa ezinye izinto ezigaywe kabusha.
Le ndlela ayizuzisi imvelo kuphela ngokunciphisa udoti kodwa futhi inikeza ukonga izindleko. Nokho, inselele isekugcineni izinga. Ukuqinisekisa ukuthi itiyela eligaywe kabusha lifana nokusebenza kwezinto ezingakaze libonwe kuyinkimbinkimbi, kudinga ukuhlolwa nokucwengisiswa okuqhubekayo.
Njengokuzinikela kuka-Taian Yueshou ekusebenziseni izikhungo zabo ezinwebekayo ukuthuthukisa okokusebenza okuxubile okuphakeme, uMartin Marietta usebenzisa izimiso zokuhlola eziqinile ukuze aqinisekise ukuthi izinto ezigaywe kabusha ziyahlangabezana nenqubo yokusebenza eqinile. Lokhu kugcizelela ekulawuleni ikhwalithi kuyisici esibalulekile sesu labo lokusungula izinto ezintsha.
Ukuzivumelanisa Nezinselele Zesimo Sezulu
Isici esisodwa sokuqanjwa kabusha esibalulekile kodwa esivame ukubukelwa phansi ukuguquguquka kwesimo sezulu. Imigwaqo ibhekana nezinselelo ezahlukahlukene ngokuya ngesimo sezulu lapho ibekwe khona, ukusuka ekushiseni okubabazekayo kuye kwezibandayo.
Ucwaningo lukaMartin Marietta lugxile ikakhulukazi ekuthuthukiseni izingoma eziguquguqukayo ze-asphalt. Lokhu kuhilela ukulungisa izakhiwo ze-binder ukuze zimelane namazinga okushisa aphezulu kanye nokuqonda umthelela wesikhathi eside wokushintsha kwesimo sezulu ezindaweni zomgwaqo.
Imithelela yalolu cwaningo mikhulu, imigwaqo ethembisayo hhayi nje kuphela eqinile kodwa futhi ephephile. Ngokuthuthuka kwemithetho yezemvelo kanye nemvamisa ekhulayo yezehlakalo zesimo sezulu esibi kakhulu, ukuzivumelanisa nezimo kubaluleke kakhulu kunangaphambili.
Ukutshala imali Ocwaningweni Nentuthuko
Ukuqamba okusha okuqhubekayo kudinga ukuzibophezela okuqinile kwe-R&D. UMartin Marietta, ngokutshala imali eningi emizamweni yabo yocwaningo, ubeka izinga eliphezulu embonini. Ngokufana nabasebenzi abaningi baka-Taian Yueshou abasetshenziselwa ukuqhubekisela phambili ukuthuthukiswa kwemishini, inkampani isebenzisa ithalente nezinsiza zabo ukuhlola ukwakheka nobuchwepheshe obusha.
Lokhu kungase kuhlanganise ukuhlola ngezibophezelo ezintsha noma ukuhlanganisa ubuchwepheshe obuhlakaniphile ku-asphalt ngokwayo ukuze kuthuthukiswe ukuqapha ukusebenza. Amandla okuxhuma izinto zomgwaqo ezinhlelweni zengqalasizinda ehlakaniphile kumelela umngcele othakazelisayo.
Ngaphezu kwalokho, ukusebenzisana namanyuvesi nezikhungo zocwaningo kuvumela indlela eguquguqukayo yokuqamba izinto ezintsha, ingene ocwaningweni lwezemfundo olusezingeni eliphezulu futhi iluhlanganise nezinhlelo zokusebenza ezisebenzayo.
Ukusebenzisana Kwekusasa Elisimeme
Ukwakhela phezu kwale mizamo ye-R&D, ukusebenzisana nozakwethu njenge Taian Yueshou I-Mixing Equipment Co., Ltd. nabanye embonini bangakha ama-synergies aqhubekisela phambili ukuqamba okusha nakakhulu. Izinsiza zokufunda nokwabelana zingasheshisa impumelelo kubuchwepheshe be-asphalt.
Ubambiswano olunjalo lubalulekile ekubhekaneni nezinselelo ezinkulu ezibhekene nemboni namuhla. Ukusimama akukhona nje ngezinto zokwakha kodwa futhi mayelana nokugqugquzela isiko lokuthuthuka okuqhubekayo kanye nomthwalo wemfanelo wemvelo.
Kafushane, indlela kaMartin Marietta yoku innovating asphalt tech akukhona mayelana nempumelelo ewubukhazikhazi kodwa kunalokho umzamo ozinzile, ozibophezele wokuthuthukisa zonke izici zomkhiqizo. Njengomsebenzi wokucophelela e-Taian Yueshou, kuhilela ukuqonda okujulile kwezinto, izinqubo, nokusebenzisana komkhiqizo wokugcina nemvelo. Lokhu kuzibophezela yikho okubahlukanisayo njengomholi wemboni.
