Ngaba isityalo se-Asphalt esiphathwayo esixutywe ne-Hot Mix sinokunciphisa iindleko zakho zokuhombisa ngesiqingatha?
Kutheni Abakhi Betshintsha Besiya Kwisityalo Esiphathwayo Se-Asphalt Esixutywe Ngobushushu—Nawe Usenokuthi Ube Naso
Yonke intwasahlobo, amasebe eendlela ezinkulu kunye neepavu zabucala zijongene nentloko efanayo: iindleko zokuthutha ziyaqhubeka zinyuka ngelixa iifestile zomsebenzi ziqhubeka zincipha. Ngena kwisityalo se-asphalt esiphathwayo esinomxube oshushu , iyunithi ekwaziyo ukutsalwa, ezakha ngokwayo ethembisa umxube omtsha kwimizuzu engama-20 yokufika. Ivakala inesibindi, akunjalo? Kodwa idatha ye-DOT karhulumente evela eTexas naseGeorgia ibonisa ukuba abakhi banciphisa isaphulelo se-18-24% kwinkcitho yezinto emva kwexesha lokuqala. Imfihlo ayikobugqi; kukususa uhambo oluya nokubuya lweemayile ezingama-60 ukuya kwindawo yokomisa ekufutshane. Zimbalwa iilori endleleni, idizili engasetyenziswanga kangako, kwaye—nantsi eyona nto ibalulekileyo—akukho mxube “othambileyo” wobusuku omele ufudunyezwe kusasa olulandelayo.
Isebenza Njani Itekhnoloji Xa Uhamba?
Khawucinge ngetreyila engama-40-ft eneebhini ezintathu ezisongwayo: i-virgin aggregate, i-RAP, kunye nothuli lwebhegi. I-feeder eguquguqukayo ilinganisa umlambo ngamnye kwiscreen esineedekhi ezintathu, ize iwise iinxalenye ezilinganiswe ngokuchanekileyo kwidramu ejikelezayo engama-6-ft. I-burner inyuka iye kwi-1,600 °F ngaphantsi kwemizuzu emithathu ngenxa ye-atomizer enoxinzelelo oluphezulu. Ngelixa idramu ijikeleza, i-PLC ilandelela umswakama ongqongileyo kwaye ilungisa ngokuzenzekelayo i-injection ye-bitumen. I-shebang yonke inikwe amandla yi-genset engama-350-kW edibana ne-Tier-4 Final—ukuze ukwazi ukubhida imisebenzi yaseCalifornia ngaphandle kokuphazamiseka kwamaphepha. Ngamafutshane, ufumana ukuchaneka kwesityalo esingashukumiyo kunye nomfanekiso wohambo lwe-carnival.
Linda, Kuthekani Ngeemvume ze-EPA?
Hayi, umbuzo oxabisa izigidi zeerandi. Uninzi lweemodeli zezityalo ze-asphalt ezishushu eziphathwayo zithunyelwa nge- EPA "Imvume yoMgangatho woMoya oQhelekileyo kwiMithombo emincinci" epakishwe kwangaphambili. Inguqulelo: ukuba imveliso yakho ihlala ingaphantsi kweetoni ezili-100,000 ngonyaka kwaye utshisa igesi yombhobho okanye idizili yesulfure ephantsi kakhulu, ngokusisiseko usendleleni ekhawulezayo. Ezinye izithili zisafuna isaziso sikawonke-wonke seentsuku ezingama-30, kodwa oko kuyoyisa isaga yeenyanga ezili-18 efunekayo kwisakhiwo esisisigxina se-400-tph. Icebiso lobuchule: gcina ikopi yesiqinisekiso sokukhutshwa komoya ngumvelisi kwibhokisi yeglavu; abahloli bayakuthanda ukubona "≤0.04 lb PM-10 ngetoni" ebhalwe ngqindilili i-Arial.
Ukunciphisa Amanani: I-ROI kwiXesha elinye
Masibale ngokukhawuleza kwiprojekthi yokulungisa umphezulu wendlela yesithili esiziikhilomitha ezimbini:
- Umthamo oqhelekileyo wokuthutha (isityalo esingashukumiyo): Iimayile ezingama-42 → $11.30 ngetoni nganye kwiilori.
- Umthamo ofunekayo: iitoni ezili-18,000.
- Ukutsha kakhulu ngenxa yokulibaziseka kweempelaveki: 3%.
Ixabiso elongezelelweyo lilonke: ≈ $230,000. Isityalo se-asphalt esiphathwayo esinomxube oshushu ophakathi siqesha i-$35,000 ngenyanga, kuquka nokulinganisa. Nokuba usigcina iinyanga ezintathu, usene-$125,000 emnyama—ngaphambi kokuba ubale iibhonasi ze-night shift okanye izohlwayo zokuzifudumeza. Owu, kwaye ndikhankanyile ukuba ungayifudusela kwisithili esilandelayo ngaphantsi kweeyure ezisibhozo? Ewe, oko kuyatshintsha umdlalo .
Ukuphelisa iintsomi: "Into ephathekayo ithetha umgangatho ophantsi"
Iingcali zakudala zifunga ukuba udinga inqaba engashukumiyo eyi-150-ft ukuze ufikelele kwi-96% yoxinano lweMarshall. Uvavanyo lokwenyani: abaxubi beedrama banamhlanje bafikelela kwi-98% ngaphakathi kwe-±0.3% yebhitumen deviation, eqinisekiswe ziigeyiji zenyukliya ezikwibhodi. Icebo lizii-paddles zesantya esiguquguqukayo ezandisa ixesha lokuhlala ngemizuzwana eli-12—zinde ngokwaneleyo ukuba zigqunywe ngokupheleleyo, zimfutshane ngokwaneleyo ukuthintela umsi oluhlaza okwesibhakabhaka. Ukuba kukho nantoni na, umxube utsha kuba akukho silo hold yemizuzu engama-45. Ngoko ke kwixesha elizayo umntu ekuxelela ukuba i-portable ilingana ne-"lukewarm tar," mcele ukuba aye kumhla wakho olandelayo wesampulu. I-Spoiler: ii-cores ziya kuthetha kakhulu kunezithuko zakho.
Iinkcukacha ezi-3 ongafanele uzijongele phantsi
- Indlela yokufudumeza: Izitshisi zepetroli ezimbini zonga i-$1.10 ngetoni xa utshintshela kwi-LNG phakathi kwexesha lokutshintsha.
- Indlu yeebhegi idelta-P:
- Ubukhulu be-drag slat: Ii-liner ze-chromium-carbide ze-⅜-intshi zinciphisa ixesha lokungasebenzi kokutshintshwa ngama-40%.
Umda we-5.5-in wc ugcina iingxowa ziphila iiyure ezingama-3,000 zokusebenza, hayi ezili-1,800.
Ukusuka kwiindlela zasezidolophini ukuya kwiindawo zomoya-ifama: Amatyala okusetyenziswa kwehlabathi lokwenyani
NgoJulayi ophelileyo, inkampani yaseColorado yayifuna iitoni ezili-11,000 ze-asphalt ene-modulus ephezulu kwindlela yokufikelela kwifama yomoya enyuke nge-11% yamanqanaba. Isityalo esinye se-asphalt esinomxube oshushu esiphathwayo sivelise umxube kwi-340 °F, iimayile ezingama-20 ukusuka kumgca wombane okufutshane. Abasebenzi bahamba ngeenyawo ezingama-2,300 iinyawo ngeshifti nganye, boyisa ixesha lemvula, kwaye babesenexesha lokuhlola amashishini okwenziwa utywala asekuhlaleni—kuba, heyi, ulungelelwaniso lomsebenzi nobomi, bantu. Amabali afanayo ayavela kwiindlela zokugawula imithi zase-Ontario nakwiindawo ze-oyile zaseTexas. Ingxoxo efanayo? Iishedyuli ezixineneyo, iindawo ezikude, kunye nokunganyamezelani kwamalungu abandayo.
Ukuthenga vs. Ukuqeshisa: Yeyiphi indlela ofanele uyithathe?
Ukuba umthamo wakho wonyaka udlula iitoni ezingama-80,000 kwaye uneminyaka emihlanu ubuncinci usemva, ukuthenga ngokuthe ngqo kubiza ngaphantsi kwe-$2.80 ngetoni nganye. Amaxabiso emali alungile ngoku—cinga nge-5.9% ye-APR kwiinyanga ezingama-72. Ukuqeshisa, kwelinye icala, kugcina imali yokusebenza kwaye kukuvumela ukuba uvavanye itekhnoloji entsha yokutshisa rhoqo ngexesha lonyaka. Izivumelwano ze-hybrid—ukuqeshisa-ukuba-ngowakho ngokuthenga kwe-30%—nazo ziyathandwa. Nokuba yeyiphi na indlela oyikhethayo, gxininisa kuqeqesho lokuqala kwifektri; ikhosi yesiqinisekiso seentsuku ezimbini inokuthintela ibango le-$40,000 lokutshisa ubushushu emgceni.
Iingxaki Zokugcinwa Kwezinto Eziqhelekileyo—Nendlela Yokuziphepha
Ewe, incwadana yokuthengisa ithi “abangasebenziyo bokuthambisa,” kodwa kuya kufuneka uthambise iirola zedrama rhoqo emva kweeyure ezingama-250. Yitsibe kube kanye, kwaye idrama iyarhubuluza njengomntwana okwi-espresso. Ngaba kukho enye impazamo entsha? Ukungayinaki i-DEF filter ye-genset; i-SCR evalekileyo inokuphazamisa isityalo sonke, ikushiye ne-50 tph endaweni ye-120 tph. Gcina i-filtration ye-$28 kwi-parts tote, uyitshintshe ngemini yemvula, kwaye uya kuba mhle. Ndikholelwe, umphathi weprojekthi yakho uya kubulela xa ishedyuli ingangeni kwiveki ezayo.
Into ephambili ekufuneka iqwalaselwe: Ukuhambahamba Kuyinzuzo
Nokuba ulungisa imingxuma embindini wedolophu okanye uphinda wakhe iindlela zesibini ezintini, isityalo se-asphalt esiphathwayo esixutywe ne-hot mix sinciphisa iindleko zothutho, sinciphise amaxesha, kwaye sigcina umgangatho uhambelana. Umothuko wesitikha ongaphambili uyaphela xa uqonda ukuba usandul' ukufumana imali yokufunda ekholejini kwisemester ngexesha elinye. Ngoko ke, ngaba umatshini omnye unganciphisa iindleko zakho zokuhombisa ngesiqingatha? Izibalo—kunye neemayile—zithi ewe. Okuseleyo kukulungisa, ujike iswitshi, kwaye ubukele ukonga kuphuma ngetoni nganye yegolide emnyama eshushu.
