Oomatshini bokugaya be-DY-300: Isisombululo esigqibeleleyo sokuvuselelwa komphezulu we-Asphalt ngokufanelekileyo

Ukungxamiseka koHlaziyo lweAsphalt oluSebenzayo: Imingeni yoShishino​

Ngaphambi kokuba sihlolisise amandla e-DY-300, kubalulekile ukuqonda imingeni enzima ejongene namaqela okulungisa i-asphalt kwihlabathi liphela. Ngokutsho kwe-International Road Federation (IRF), ngaphezulu kwama-40% eendlela ze-asphalt zehlabathi zifuna ukuhlaziywa kwiminyaka emi-5-7 yokwakhiwa, kodwa iindlela eziqhelekileyo ziyasokola ukuhlangabezana nale mfuno. Umzekelo, ukugaya ngesandla—ukuxhomekeka kwizixhobo eziphathwayo—kunokucubungula kuphela iimitha zesikwere ezingama-20-30 zomphezulu ngeyure, ngelixa oomatshini bokugaya abadala behlala beshiya iindawo ezingalinganiyo ezifuna ukuthambisa okongeziweyo, okwandisa ixesha kunye neendleko zeprojekthi.​

Ngaphezu koko, inkunkuma yezinto ezibonakalayo yingxaki enkulu. Ukulungiswa komphezulu ngokwesiko kususa zonke iileya ze-asphalt (ngokuqhelekileyo i-5-10 cm) nokuba kuphela yi-1-2 cm ephezulu eyonakeleyo, nto leyo ekhokelela ekubeni izinto ezilahliweyo zibe ngaphezulu kwama-30-40%, nto leyo ekhokelela ekukhutshweni kwenkunkuma ngama-30-40% kuphela. Oku akunyusi nje iindleko zokusingqongileyo kodwa kukwanyusa neendleko zokuveliswa kwe-asphalt entsha. Ukuvalwa kweendlela kuyayiqinisa le ngxaki: ukuvalwa kwendlela enye kwindlela exakekileyo kunokubangela ukulibaziseka kweendleko zezithuthi.

I-1,200–3,000 ngeyure, ngokutsho kwe-American Association of State Highway and Transportation Officials (AASHTO). Le mingeni igxininisa imfuneko yesisombululo esilinganisela isantya, ukuchaneka, kunye nokuzinza—kanye oko kunikezelwa ngumatshini wokugaya we-DY-300.​

Amandla angundoqo e-DY-300: Ubuchule boBunjineli bokuHlaziywa​

I-DY-300 yenzelwe ukujongana nemida yeendlela zemveli ngokusebenzisa uluhlu lweempawu eziphambili ezibeka phambili ukusebenza kakuhle, ukuchaneka, kunye nokulungelelana komsebenzisi. Eyona nto iphambili, umatshini usebenzisa inkqubo ye-hydraulic ene-torque ephezulu edityaniswe ne-drum yokusila eyi-1.8-meter ububanzi—ebanzi kakhulu kune-drum ye-1.2-1.5-meter yeenkampani ezininzi ezikhuphisana nazo. Le drum ebanzi ivumela i-DY-300 ukuba igubungele ukuya kuthi ga kwi-120 square metres yomphezulu we-asphalt ngeyure, ukwanda kwemveliso ngama-40-60% xa kuthelekiswa neematshini zokusila eziqhelekileyo. Umzekelo, umgama wekhilomitha e-1 wendlela eneendlela ezimbini (efuna i-4,000 square metres yokusila) unokugqitywa kwiiyure ezingama-34 kuphela nge-DY-300, xa kuthelekiswa neeyure ezingama-50-60 ngeemodeli ezindala.​

Ukuchaneka lolunye uphawu lwe-DY-300. Ixhotyiswe nge-GPS-guided deep control kunye ne-laser leveling technology, umatshini ugcina ukuchaneka kobunzulu bokugaya obuyi-±1 mm—okubalulekileyo ekuqinisekiseni ukulungiswa komphezulu okufanayo ngaphambi kokuphinda ubekwe kwakhona. Oku kususa isidingo sokuthambisa okwesibini, ukunciphisa amanyathelo eprojekthi kunye nokunciphisa inkunkuma yezinto. Idrama yokugaya ngokwayo ifakwe amazinyo e-tungsten carbide angama-80, acwangciswe ngendlela ejikelezayo ukuqinisekisa ukusika rhoqo kunye nokuthintela ukukrazuka komphezulu. La mazinyo anokutshintshwa, kunye nobomi bokusetyenziswa rhoqo beeyure ezingama-50-80—ubude obuphindwe kabini kunamazinyo entsimbi aqhelekileyo—okunciphisa iindleko zokulungisa kunye nexesha lokungasebenzi.​

Amava omsebenzisi awajongwa. I-DY-300 inoyilo lwekhabhathi olune-ergonomic controls, isikrini sesikrini esichukumisayo esiyi-intshi ezili-10, kunye nokubonakala kwama-degree angama-360—okunciphisa ukudinwa komqhubi ngexesha lokutshintshana okude. Lo matshini uncinci (ubude beemitha eziyi-6.2, ububanzi beemitha eziyi-2.5) kwaye unomda wokujika weemitha eziyi-4.8, okwenza ukuba ufaneleke kwiindawo zasezidolophini ezineendlela ezimxinwa okanye iikona ezixineneyo. Kwiiprojekthi ezinkulu, i-DY-300 inokudityaniswa nenkqubo yokuhambisa izinto ezizinikeleyo elayisha ngokuthe ngqo i-asphalt egayiweyo kwiilori, isusa isidingo sokugcina esiphakathi kunye nokuphucula imisebenzi.​

Izicelo zeHlabathi lokwenyani: Ukubonisa ukusebenza kakuhle​

Ukusebenza kwe-DY-300 akupheleli nje kwingcamango—kuye kwaqinisekiswa kwiiprojekthi ezininzi zokuvuselela ezidumileyo kumazwekazi. Ngo-2023, isixeko saseBerlin, eJamani, sasebenzisa oomatshini abali-12 be-DY-300 ukuvuselela iikhilomitha ezili-15 zeendlela zasezidolophini ngaphambi komsitho omkhulu wamazwe ngamazwe. Le projekthi yayifuna ukugawula iimitha zesikwere ezingama-60,000 zomphezulu we-asphalt kunye nobunzulu obujoliswe kubo obuyi-2 cm (ukulungisa iintambo kunye nokuqhekeka). Besebenzisa itekhnoloji ye-GPS ye-DY-300, iqela lifikelele kubunzulu obufanayo kwi-98% yendawo, benciphisa inkunkuma yezinto ezibonakalayo ngama-35% xa kuthelekiswa neprojekthi yabo ka-2021 (eyayisebenzisa oomatshini abadala bokugaya). Le projekthi yagqitywa kwiintsuku ezingama-28—iiveki ezimbini ngaphambi kwexesha elicwangcisiweyo—ukunciphisa ukuphazamiseka kwezithuthi embindini wesixeko.​

E-United States, iSebe lezoThutho laseTexas (i-TxDOT) lithumele oomatshini be-DY-300 ukulungisa indawo engama-20 eekhilomitha ye-Interstate 35, eyayinemingxuma enzima kunye nemingxunya ngenxa yezithuthi ezininzi zeelori. Inkqubo ye-DY-300 ene-torque ephezulu yayivumela ukuba ikwazi ukugaya kwi-asphalt eqinileyo (exineneyo kangangeminyaka eli-10) ngaphandle kokunciphisa isantya, ngelixa inkqubo yokuhambisa ivumela ukulayisha okuqhubekayo kwezinto ezigayiweyo. I-TxDOT ibike ukwanda kwemveliso yemihla ngemihla ngama-42% xa kuthelekiswa nezixhobo zayo zangaphambili, kwaye i-asphalt egayiweyo yaphinda yasetyenziswa kwindawo (ixutywe ne-aggregate entsha) ukuvelisa i-30% ye-asphalt entsha esetyenziselwa ukuvuselela umphezulu—ukunciphisa iindleko zezinto nge-$120,000.​

Ezi meko zibonisa inzuzo ephambili ye-DY-300: ukukwazi kwayo ukuziqhelanisa neemfuno ezahlukeneyo zeprojekthi, ukusuka kwiindlela zasezidolophini ukuya kwiindlela ezinkulu, kunye nokubonelela ngeziphumo ezihambelanayo ngokubhekiselele kwisantya, ukuchaneka, kunye nokonga iindleko.​

Uzinzo: Ukuhambelana neenjongo zeHlabathi zeNdalo​

Kwixesha lokugxila ngakumbi ekuzinzeni, i-DY-300 ivelele ngoyilo lwayo olunobuhlobo nokusingqongileyo. Njengoko kukhankanyiwe, ukugaywa ngokuchanekileyo komatshini kunciphisa inkunkuma yezinto nge-30-40% xa kuthelekiswa neendlela zemveli. Ngaphezu koko, i-asphalt egayiweyo (eyaziwa ngokuba yi-recycled asphalt pavement, okanye i-RAP) ayilahlwa nje kuphela—ingaphinda isetyenziswe ibe yi-asphalt mixes entsha. Inkqubo yokugaywa kwe-DY-300 ivelisa i-RAP enobukhulu obufanayo be-particle, okwenza kube lula ukuyidibanisa kwi-mixes emitsha (ukuya kuthi ga kwi-50% ye-RAP kwezinye iimeko), kunciphisa imfuneko yee-aggregates kunye ne-bitumen.​

Ukusebenza kakuhle kwamandla yenye indlela enamandla ngayo. I-DY-300 isebenzisa ipompo ye-hydraulic eguquguqukayo elungisa amandla aphumayo ngokusekelwe kumthwalo, endaweni yokusebenza ngamandla apheleleyo rhoqo. Oku kunciphisa ukusetyenziswa kwepetroli nge-15–20% (xa kuthelekiswa neepompo ezifudukayo ezisisigxina), kunciphisa ukukhutshwa kwekhabhoni malunga neetoni eziyi-0.8 kwiiyure ezili-100 zokusebenza. Lo matshini ukwahlangabezana nemigangatho ye-Euro Stage V kunye ne-EPA Tier 4 Final emissions, ukuqinisekisa ukuthotyelwa kwemigaqo engqongqo yokusingqongileyo yehlabathi.​

Isiphelo: I-DY-300 njengesixhobo sokuvuselela i-Asphalt enobuchule​

Umatshini wokugaya i-DY-300 awuyonto nje yesixhobo—sisisombululo esibanzi esijongana nemingeni ephambili yokuvuselelwa komphezulu we-asphalt: ukungasebenzi kakuhle, ukungachaneki, inkunkuma, kunye nempembelelo yokusingqongileyo. Ngokudibanisa imveliso ephezulu (iimitha zesikwere ezili-120 ngeyure), ukuchaneka okugqwesileyo (±1 mm ulawulo lobunzulu), kunye noyilo oluzinzileyo (inkunkuma encitshisiweyo kunye nokukhutshwa komoya), i-DY-300 ivumela ii-arhente zothutho kunye nabakhi ukuba bagqibezele iiprojekthi ngokukhawuleza, ngexabiso eliphantsi, kwaye ngomgangatho omncinci wokusingqongileyo.​

Njengoko iziseko zophuhliso zehlabathi zikhula kwaye imfuno yokugcinwa ngokufanelekileyo ikhula, i-DY-300 imele ikamva lokuvuselelwa kwe-asphalt—ikamva apho iindlela zilungiswa ngokukhawuleza, ngokukhuselekileyo, nangokuzinzileyo, kuqinisekiswa ukuba uthungelwano lwezothutho luhlala luthembekile kangangeminyaka emininzi ezayo. Kuyo nayiphi na intlangano efuna ukuphucula iinkqubo zayo zokulungiswa kwe-asphalt, i-DY-300 ayilulo ukhetho nje kuphela—yisisombululo esiphezulu.
