Isebenza Kanjani Isitshalo Sokuxuba I-Asphalt Esiphinda Sisetshenziswe?

Abakhi bemigwaqo bangabuyisa i-aggregate kanye ne-binder endala emgwaqweni oqoshiwe esikhundleni sokuyiphatha njengemfucuza. Inselele ukucubungula leyo nto ngaphandle kokulahlekelwa ukulawula ukwakheka kwe-gradiation, izinga lokushisa, noma ukuhambisana kwe-mix.

Lo mhlahlandlela ulandela indlela yokuvuselela kabusha kusukela ekulungiseleleni nasekufudumaleni kwe-RAP kuya ekulinganisweni, ekuxubeni, ekulawuleni ikhwalithi, kanye nokusebenza kwesitshalo sonke. Qhubeka ufunda ukuze ufunde kabanzi mayelana isitshalo sokuxuba i-asphalt kabusha .

Iyini Isitshalo Sokuxuba I-Asphalt Esiphinda Sisetshenziswe?

Isitshalo se-asphalt esiphinda sisetshenziswe sikhiqiza ingxube ye-asphalt eshisayo ene-asphalt pavement ephinde yasetshenziswa, ebizwa ngokuthi i-RAP. I-RAP iqukethe i-aggregate embozwe nge-asphalt binder endala.

Isitshalo kumele sibe nosayizi, silinganise, sifudumale, futhi sihlanganise i-RAP. Umgomo ingxube eqinile ehlangabezana neresiphi yephrojekthi ngenkathi kusetshenziswa izinto ezibuyiselwe. Ukuvuselelwa okushisayo kungafakwa esitshalweni noma kwengezwe ngohlelo lokuvuselela. Abathengi bangakwazi buyekeza ukucushwa kwesitshalo sokuvuselela kabusha esihlanganisiwe uma uqhathanisa izakhiwo.

Indlela i-RAP elungiselelwa ngayo ukuphinda isetshenziswe

Ikhwalithi ye-RAP iqala ngaphambi kokuba izinto zingene embhoshongweni wokuxuba. Ukulungiselela okungekuhle kudala amazinga okuphakelwa angazinzile futhi kwenza ukulawula ukuxuba kube nzima.

◆ Ukuchoboza Nokuhlola i-RAP:

Indlela egayiwe ingafika ngobukhulu obuxubile futhi ingaba nezingcezu ezinkulu kakhulu. Ukuchoboza kunciphisa izingcezu ezinkulu, kuyilapho ukuchoboza kuhlukanisa izingxenyana ezisebenzisekayo. Ukuhlukanisa i-RAP ibe ngosayizi olawulwayo kuthuthukisa ukuhambisana kokudla. Kuphinde kunikeze abaklami bengxube ukulawula ukuhlelwa kwezingxenye kanye nomnikelo we-binder obuyiselwe. Uhlelo oluzinikele lokuchoboza nokuhlola i-RAP lungalungisa izinto ezibuyiselwe ngaphambi kokudla izitshalo.

◆ Ukugcinwa Nokuphakelwa Kwezinto:

I-RAP kufanele igcinwe ngokomthombo noma usayizi lapho izakhiwo zihluka. Lokhu kunciphisa izinguquko ekulinganisweni noma kokuqukethwe kwe-binder. Ama-feed bin abese elinganisa umgwaqo we-asphalt obuyiselwe ngesivinini esibekiwe. Ukugeleza okungajwayelekile kushintsha iphesenti eliphinde lasetshenziswa kusuka kwelinye ibhetshi kuya kwelinye.

Indlela i-RAP efudunyezwa ngayo esitshalweni sokuxuba

I-RAP yokushisa idinga ukwelashwa okuhlukile kune-clean virgin aggregate. I-binder endala isivele igugile, ngakho ukushisa ngokweqile kungayonakalisa kakhulu.

✔ Ukushisa kwe-RAP okulawulwayo:

Uhlelo lokusebenzisa kabusha ludlulisela ukushisa okwanele ku-RAP ukuze kususwe umswakama futhi kufinyelele esimweni sokuxuba esidingekayo. Ukuvezwa komlilo oqondile kufanele kukhawulelwe ezinhlelweni ezenzelwe izinto ezibuyiselwe. Ezinye izitshalo zifudumeza i-RAP ngesigubhu esihlukile sokusebenzisa kabusha. Ezinye zisebenzisa i-hot virgin aggregate ukudlulisa ukushisa ngesikhathi sokuxuba.

✔ Ukuphathwa Kwezinga Lokushisa:

Umswakama we-RAP uthinta ukuthi uhlelo ludinga amandla angakanani. Izinto ezimanzi zithatha isikhathi eside ukoma futhi zinganciphisa umkhiqizo wesitshalo. Abasebenzi babheka izinga lokushisa le-RAP, izinga lokushisa elihlanganisiwe, kanye nezinga lokushisa lokugcina lengxube ndawonye. Ibhalansi incike kuresiphu kanye nomklamo wesitshalo.

Indlela I-Asphalt Ephinde Yasetshenziswa Exutshwa Ngayo

Uma isilungisiwe futhi ifudunyeziwe, i-RAP kumele ifake iresiphi ngesilinganiso esifanele. Uhlelo lokulawula luhlanganisa izinto ezibuyiselwe nezinto ezintsha.

▶ Ukulinganisa kwe-RAP:

Iphesenti le-RAP kufanele lilandele ukwakheka kwengxube okuvunyelwe. Ukunemba kokuphakelwa kubalulekile ngoba i-RAP inikela kokubili i-aggregate kanye ne-aged binder.

▶ Izinto Eziyi-Virgin kanye Ne-Binder:

I-aggregate entsha ilungisa ukuhlelwa kwe-gradation lapho kudingeka khona. I-asphalt binder entsha ibuyisela okuqukethwe kwe-binder okudingekayo ngeresiphi. Ezinye izingxube zingasebenzisa futhi i-ejenti yokuvuselela noma yokuvuselela. Ukusetshenziswa kwayo kuncike esimweni se-binder kanye nezidingo zokwakheka kwengxube.

▶ Ukuxuba Nokukhipha Igesi:

Umxubi kumele asakaze izinto ezibuyiselwe kanye nezingasebenzi ngokulinganayo ngaphambi kokukhipha. Isikhathi sokuxuba kufanele sisekele ukumbozwa okufanayo ngaphandle kokunciphisa ukukhiqizwa ngokungadingekile. I-asphalt esetshenzisiwe eseqediwe bese idluliselwa esibayeni sokugcina noma emalolini ukuze kugaywe.

Ithebula Lenqubo Yokuxuba I-Asphalt Kabusha

Indlela Isitshalo Esigcina Ngayo Ikhwalithi Ehlanganisiwe

Inqubo enhle yokuvuselela kabusha incike ekufakweni okuphindaphindwayo kanye nokulawula okunembile. Izinguquko ezincane zezinto zingathinta ingxube yokugcina ngokushesha.

◇ Ukuvumelana Kwezinto Ezibonakalayo:

Abaqhubi kufanele baqaphe ukuhlelwa kwe-RAP, umswakama, kanye nokuqukethwe kwe-binder. Izinqwaba ezihlukene ziyasiza lapho izinto ezibuyiselwe zivela emithonjeni ehlukene. Ukufakwa okuqhubekayo kwenza i-asphalt ye-RAP ibe lula ukuyilinganisa futhi kunciphisa ukulungiswa ngesikhathi sokukhiqiza.

◇ Ukulawula Izinga Lokushisa:

Izinga lokushisa kumele libe phezulu ngokwanele ukuze kuhlanganiswe kahle, kodwa ukushisa ngokweqile okungadingekile kufanele kugwenywe. Lokhu kuvikela i-binder endala futhi kunciphise ukukhishwa okungafuneki.

◇ Ukulawulwa Kwenqubo Okuzenzakalelayo:

Izilawuli zesimanje zixhumanisa iziphakeli, izinhlelo zokulinganisa, amazinga okushisa, isikhathi sokuxuba, kanye namarekhodi okukhiqiza. Ama-alamu angabonisa izimo ezingavamile ngaphambi kokuba inani lithinteke.

Yini Ethinta Ukusebenza Kwezitshalo Zokusebenzisa Kabusha?

Umkhiqizo wesitshalo uncike kumthamo ongaphezu kolinganiselwe. Isimo sendlela ye-asphalt ebuyiselwe kanye nephesenti lokusebenzisa kabusha kungashintsha isivinini sangempela sokukhiqiza.

☀ Ikhwalithi ye-RAP kanye nomswakama:

I-Wet RAP idla ukushisa okwengeziwe futhi inganciphisa ukuphuma kwayo. Ukungcola, imithombo exubile, kanye nosayizi ongazinzile nakho kwenza umkhiqizo ungabikezeleki. Indlela ye-asphalt ebuyiselwe ingagcina umswakama omningi ngesikhathi sokugcina.

☀ Isilinganiso Sokusebenzisa Kabusha:

Amaphesenti aphezulu e-RAP andisa umthwalo wezinto ezibuyiselwe ezinhlelweni zokushisa nokulawula. Isilinganiso esisebenzayo sincike ekucushweni kwesitshalo kanye nomklamo wokuxuba.

☀ Izidingo Zokukhiqiza:

Umkhiqizo odingekayo, izinguquko zeresiphi, umthamo wokugcina, kanye nezincazelo zephrojekthi konke kuthinta ukukhethwa kwesitshalo. Qondanisa imishini nezimo zokusebenza, hhayi nje umthamo wepuleti legama.

Isiphetho :

Ukulungiswa kwe-RAP okuhlelekile, ukufudumeza, ukulinganisa kanye nokulawula kuyadingeka esitshalweni sokuxuba i-asphalt esiphinde sasetshenziswa. Ukuphathwa kwezinto kanye nokuphindaphindwa kwazo kubaluleke kakhulu kunephesenti lokuvuselela eliyinhloko.

Kwabonkontileka abahlela ukutshalwa kwezimali, Isitshalo se-Asphalt se-TTM   inikeza indlela ewusizo yokuqhubekela phambili. Sigxile emishinini yokuxuba i-asphalt kanye nokuvuselela kusukela ngo-2004. Isayithi lethu libika amalungelo obunikazi angu-562 kanye nokuthengiswa emazweni nasezifundeni ezingaphezu kuka-60.

Njengomkhiqizi kanye nomhlinzeki wefektri yokuxuba i-asphalt kabusha, sisekela ukukhethwa kwemishini, ukuqaliswa kokusebenza, isevisi ekude, kanye nezidingo zezingxenye ezisele. Sithumelele isimo sakho se-RAP, isilinganiso sokusetshenziswa kabusha okuqondiwe, umkhiqizo odingekayo, kanye nemininingwane yephrojekthi. Singabuyekeza futhi sincome ukusethwa komkhiqizo kwezimo zakho zokusebenza.

Imibuzo Evame Ukubuzwa

Umbuzo 1. I-RAP kufanele igcinwe kanjani ngaphambi kokuba ingene esitshalweni se-asphalt se-RAP?

Impendulo: Gcina izinqwaba ze-RAP zihlanzekile futhi zihlukene lapho imithombo noma osayizi behlukile. Nciphisa ukuvezwa komswakama futhi ugweme imikhuba ehlanganisa izinto zibe amaqoqo aqinile.

Umbuzo 2. Ingabe isitshalo se-asphalt esikhona singathuthukiswa ngohlelo lwesitshalo se-asphalt esiphinde sisetshenziswe?

Impendulo: Yebo, ezinye izitshalo zingayamukela imishini yokuvuselela kabusha ye-modular. Ukuhambisana kuncike ekuhleleni, ekulawuleni, kumthamo wokuxuba, ekuhleleni kokushisa, kanye namaphesenti e-RAP aqondiwe. I-TTM ibala kokubili imishini yokuvuselela kabusha ehlanganisiwe kanye neyengeziwe ohlelweni lwayo lomkhiqizo lwamanje.

Umbuzo 3. Yiziphi izindawo zokulungisa ezidinga ukunakwa okwengeziwe lapho kucutshungulwa i-asphalt ephinde yasetshenziswa?

Impendulo: Bukela iziphakeli ze-RAP, izikrini, ama-conveyor, ama-drum, izinzwa zokushisa, ukuqoqwa kothuli, kanye nokuguguleka kwe-mixer. Izinto ezinamathelayo ezibuyiselwe zingandisa ukwakheka ezindaweni zokudlulisa.
