Ehlabathini leziseko ezingundoqo, ukutsha kwitekhnoloji ye-asphalt akusoloko kuyindaba yephepha eliphambili, kodwa iinkampani ezifana noMartin Marietta zithe cwaka zityhala imida kwaye zitshintsha ubuso bokwakhiwa kweendlela. Ngelixa ibali eliqhelekileyo lihlala lijikeleza kumacandelo etekhnoloji abonakalayo, ukuveliswa kwe-asphalt kubaluleke kakhulu. UMartin Marietta, ukwakha kumashumi eminyaka yamava, ukhokela inkqubela phambili enokuthi ingatshintshi nje indlela ezakhiwe ngayo kodwa nendlela ezisebenza ngayo ekuhambeni kwexesha.
Ukuqonda iSiseko
Omnye unokucinga ukuba i-asphalt ngumxube olula we-aggregates kunye ne-binder, kodwa inyaniso inzima kakhulu. UMartin Marietta, njengentanga yeshishini uTaian Yueshou Mixing Equipment Co., Ltd., uyazi ukuba into entsha kule ntsimi ihlala ibandakanya ukucokisa onke amacandelo ukuze kuphuculwe ukusebenza kakuhle. Kanye ngendlela uTaian Yueshou asebenzise ngayo indawo yabo enkulu yomhlaba kunye nezixhobo eTshayina ukuqhubela phambili itekhnoloji yezixhobo zokuxuba, uMartin Marietta usebenzisa uphando olubanzi kwiinkqubo zabo zokuvelisa i-asphalt.
Ngokomzekelo, bajolise ekuphuculeni ukuqina kunye nokuzinza. Oku akubandakanyi izixhobo kuphela kodwa neenkqubo-ulawulo lobushushu ngexesha lokuxuba, ukudityaniswa okuchanekileyo kwee-aggregates, kunye neendlela ezintsha zokurisayikilisha.
Ukusetyenziswa kwehlabathi lokwenyani oku kunokubonwa kuphuhliso lwe-asphalt yomxube ofudumeleyo. Olu hlobo lwe-asphalt luveliswa kumaqondo okushisa aphantsi xa kuthelekiswa ne-asphalt yendabuko eshushu, ukonga amandla kunye nokunciphisa ukukhutshwa. Zezi ntlobo zeenkcukacha ezibeka ngokwenene iinkokeli zeshishini.
Ukuphumeza ubuChwephesha bokuRisayikilishwa
Ukusetyenziswa kwezinto ezisetyenzisiweyo kwi-asphalt akuyona into entsha, kodwa uMartin Marietta uye waqhubela phambili oku ngokunyusa umgangatho kunye nepesenti yezinto ezihlaziyiweyo ngaphandle kokuphazamisa ingqibelelo yezinto. Ubuchule ababusebenzisayo bubandakanya ukusebenzisa i-asphalt pavement ebuyiselweyo (RAP) kunye nokubandakanya ezinye izinto ezihlaziyiweyo.
Le ndlela ayincedi nje kuphela indalo esingqongileyo ngokunciphisa inkunkuma kodwa ikwabonelela ngogcino lweendleko. Noko ke, ucelomngeni lusekugcineni umgangatho. Ukuqinisekisa ukuba i-asphalt ehlaziyiweyo ihambelana nokusebenza kwezixhobo ezinyulu kuyinkimbinkimbi, ifuna uvavanyo oluqhubekayo kunye nokulungiswa.
Njengokuzinikela kukaTaian Yueshou ekusebenziseni amaziko abo abanzi ukuphuhlisa izixhobo zokuxuba ezikumgangatho ophezulu, uMartin Marietta usebenzisa iiprothokholi zovavanyo olungqongqo ukuqinisekisa ukuba imathiriyeli ehlaziyiweyo iyahlangabezana neendlela ezingqongqo zokusebenza. Olu gxininiso kulawulo lomgangatho yinkalo ebalulekileyo yesicwangciso sabo sokuqalisa izinto ezintsha.
Ukuziqhelanisa nemingeni yeMozulu
Enye inkalo yokutsha ebalulekileyo kodwa ehlala ijongelwa phantsi kukuziqhelanisa nemozulu. Iindlela zijongene nemiceli mngeni eyahluka-hlukeneyo ngokuxhomekeke kwimozulu apho zibekwe khona, ukusuka kubushushu obugqithisileyo ukuya kwiimeko eziqhaqhazelisa amazinyo.
Uluhlu lophando lukaMartin Marietta lugxininise ngakumbi ekuphuhliseni iingoma ze-asphalt eziguquguqukayo. Oku kubandakanya ukulungiswa kweempawu zokubopha ukuze zimelane nobushushu obugqithisileyo kunye nokuqonda ifuthe lexesha elide lokutshintsha kwemozulu kumphezulu wendlela.
Iimpembelelo zolu phando zinkulu, iindlela ezithembisayo ezinganeli nje ukomelela kodwa nezikhuselekileyo. Ngokuguquguquka kwemimiselo yokusingqongileyo kunye nokunyuka kwamaxesha okunyuka kweziganeko zemozulu ezibi kakhulu, ukulungelelanisa kubaluleke kakhulu kunangaphambili.
Utyalo-mali kuPhando noPhuhliso
Utshintsho oluqhubekayo lufuna ukuzibophelela okuqinileyo kwe-R&D. UMartin Marietta, ngokutyala imali eninzi kwiinzame zabo zophando, ubeka umgangatho ophezulu kwishishini. Ngokufana nabasebenzi abaninzi bakaTaian Yueshou abasetyenziselwa ukuqhubela phambili ukuveliswa kwezixhobo, inkampani iphakamisa italente yabo kunye nezixhobo zokuphonononga iindlela ezintsha kunye nobuchwepheshe.
Oku kunokubandakanya ukuzama izibophelelo ezintsha okanye ukudibanisa itekhnoloji ehlakaniphile kwi-asphalt ngokwayo ukuphucula ukujonga ukusebenza. Amandla okudibanisa izixhobo zendlela kwiinkqubo zeziseko ezihlakaniphileyo kubonisa umda othakazelisayo.
Ngaphaya koko, ukusebenzisana neeyunivesithi kunye namaziko ophando kuvumela indlela eguquguqukayo ngakumbi yokusungula izinto ezintsha, ukungena kuphando oluphezulu lwezemfundo kunye nokuludibanisa kwizicelo ezisebenzayo.
Ukusebenzisana kwiKamva eliZinzileyo
Ukwakha kwezi nzame ze-R&D, intsebenziswano namahlakani afana Taian Yueshou Mixing Equipment Co., Ltd. kunye nabanye kwishishini banokudala ii-synergies eziqhubela ukuqamba izinto ezintsha nangakumbi. Ukufunda ngokudibeneyo kunye nezibonelelo ekwabelwana ngazo kunokukhawulezisa impumelelo kwitekhnoloji ye-asphalt.
Ubudlelwane obunjalo bubalulekile ekujonganeni neminye imingeni emikhulu ejongene neshishini namhlanje. Uzinzo alukho malunga nemathiriyeli kuphela kodwa malunga nokukhuthaza inkcubeko yophuculo oluqhubekayo kunye noxanduva lwendalo.
Isishwankathelo, indlela kaMartin Marietta yoku iteknoloji ye-asphalt entsha Ayithethi malunga neempumelelo eziqaqambileyo kodwa ngumzamo ozinzileyo, ozinikeleyo wokuphucula yonke inkalo yemveliso. Njengomsebenzi ocokisekileyo eTaian Yueshou, kubandakanya ukuqonda okunzulu kwezinto, iinkqubo, kunye nokusebenzisana kwemveliso yokugqibela kunye nokusingqongileyo. Oku kuzibophelela kuko okubenza bahluke njengenkokeli yoshishino.
