Munyika yezvivakwa, iyo innovation muasphalt tekinoroji haisi nguva dzese-peji nhau, asi makambani akaita saMartin Marietta ari kupinza chinyararire miganhu uye achichinja chiso chekugadzirwa kwemigwagwa. Nepo rondedzero yakajairika ichiwanzo tenderera kune anooneka tech zvikamu, iyo innovation muasphalt yakakoshawo. Martin Marietta, achivaka pamakumi emakore echiitiko, ari kutungamira budiriro dzinogona kusangoshandura mavakirwo emigwagwa asiwo maitiro aanoita mukufamba kwenguva.
Kunzwisisa Zvinokosha
Mumwe anogona kufunga kuti asphalt ingori musanganiswa wakapusa weaggregates uye binder, asi chokwadi chakanyanya kuoma. Martin Marietta, senge indasitiri wezera Taian Yueshou Mixing Equipment Co., Ltd., anoziva kuti hunyanzvi mundima iyi kazhinji hunosanganisira kunatsa chikamu chese kuti ugone kuita. Semashandisiro akaita Taian Yueshou nzvimbo yavo yakakura uye zviwanikwa muChina kufambisira mberi matekinoroji ekusanganisa michina, Martin Marietta anoshandisa tsvakiridzo yakakura kune yavo yekugadzira asphalt maitiro.
Semuenzaniso, vanotarisa pakuvandudza kusimba uye kusimba. Izvi zvinosanganisira kwete chete zvigadzirwa asiwo maitiro-kudzora tembiricha panguva yekusanganiswa, musanganiswa chaiwo wezviunganidzwa, uye nzira itsva dzekudzokorora.
Imwe chaiyo-yepasirese application iyi inogona kuoneka iri mukuvandudza inodziya-musanganiswa asphalt. Rudzi urwu rweasphalt runogadzirwa pamatembiricha akadzikira kana ichienzaniswa neyechinyakare inopisa-musanganiswa asphalt, kuchengetedza simba uye kuderedza kuburitswa. Idzi ndidzo mhando dzeruzivo dzinonyatso siyanisa vatungamiriri veindasitiri.
Kushandisa Nzira Dzokudzokorodza
Kushandiswa kwezvinhu zvakadzokororwa muasphalt hakusi kutsva, asi Martin Marietta akasundira izvi mberi nekusimudzira mhando uye muzana yezvakadzokororwa zvemukati pasina kukanganisa kutendeseka kwezvinhu. Matekiniki avanoshandisa anosanganisira kushandisa yakadzoserwa asphalt pavement (RAP) uye kubatanidza zvimwe zvinogadzirwazve.
Iyi nzira haingobatsiri zvakatipoteredza nekuderedza tsvina chete asiwo inopa kuchengetedza mari. Zvisinei, dambudziko riri pakuchengeta unhu hwakanaka. Kuve nechokwadi chekuti asphalt yakadzokororwa inoenderana nekushanda kwezvinhu zvemhandara yakaoma, inoda kuenderera kuedzwa uye kugadziridzwa.
Kufanana nekuzvipira kwaTaian Yueshou pakushandisa zvivakwa zvavo zvakakura kugadzira michina yekusanganisa yepamusoro, Martin Marietta anoshandisa mapuroteni ekuyedza akasimba kuti ave nechokwadi chekuti zvinhu zvakadzokororwa zvinosangana nemaitiro akasimba ekuita. Uku kukoshesa kutonga kwemhando chinhu chakakosha chehurongwa hwavo hwekuvandudza.
Kuchinjira kuMatambudziko Emamiriro ekunze
Chimwe chinhu chekuvandudza icho chakakosha asi chinowanzo tarisirwa pasi ndechekuenderana nemamiriro ekunze. Migwagwa inotarisana nematambudziko akasiyana-siyana zvichienderana nemamiriro ekunze kwayakaradzikwa, kubva pakupisa kwakanyanya kusvika kuchando.
Martin Marietta's research division yanga yakatarisana zvakanyanya nekugadzira inochinjika asphalt nziyo. Izvi zvinosanganisira kushandura zvivakwa zvebhainda kuti zvimire kutonhora kwakanyanya uye kunzwisisa kukanganiswa kwenguva refu kwekushanduka kwemamiriro ekunze pamigwagwa.
Zvinorehwa netsvagiridzo iyi zvakakura, migwagwa inovimbisa iyo isiri chete kusimba asi zvakare yakachengeteka. Nekushanduka kwemitemo yezvakatipoteredza uye kuwedzera kuwanda kwezviitiko zvemamiriro ekunze zvakanyanya, kuchinjika kwakakosha kupfuura kare.
Kuisa mari muKutsvakurudza uye Kubudirira
Kuenderera mberi kwekuvandudza kunoda kuzvipira kwakasimba kweR&D. Martin Marietta, nekudyara zvakanyanya mumabasa avo ekutsvagisa, ari kuseta mwero wepamusoro muindasitiri iyi. Zvakafanana nevashandi veTaian Yueshou vakawandisa vanoshandiswa kusundira mberi zvigadzirwa zvemichina, kambani inoshandisa tarenda ravo nezviwanikwa kuti vaongorore magadzirirwo matsva uye matekinoroji.
Izvi zvinogona kusanganisira kuyedza nemabhainda matsva kana kubatanidza tekinoroji yakangwara muasphalt pachayo kuvandudza mashandiro ekutarisa. Iko kugona kwekubatanidza zvinhu zvemumugwagwa kune akangwara masisitimu ezvivakwa inomiririra muganhu unonakidza.
Uyezve, kushandira pamwe nemayunivhesiti uye masangano ekutsvagisa kunobvumira nzira ine simba yekuvandudza, kubata mukutsvagisa kwepamusoro-soro kwedzidzo uye kuibatanidza mukushandisa zvinoshanda.
Kudyidzana Kweramangwana Rakasimba
Kuvaka pane izvi R&D kuedza, kushandira pamwe nevabatsiri vakaita Taian Yueshou Mixing Equipment Co., Ltd. nevamwe vari muindastiri vanogona kugadzira kuwirirana kunosimudzira hunyanzvi zvakanyanya. Kudzidza pamwe chete uye zviwanikwa zvakagovaniswa zvinogona kukurumidzira kubudirira muasphalt tekinoroji.
Kudyidzana kwakadaro kwakakosha pakugadzirisa mamwe matambudziko makuru akatarisana neindasitiri nhasi. Sustainability haisi yezvishandiso chete asiwo nezvekusimudzira tsika yekuenderera mberi kwekuvandudza uye mutoro wezvakatipoteredza.
Muchidimbu, maitiro aMartin Marietta kune innovating asphalt tech haisi yezvinoshamisira asi kungoyedza, yakazvipira kuedza kuvandudza chikamu chose chechigadzirwa. Kufanana nebasa rekuchenjera paTaian Yueshou, rinosanganisira kunzwisisa kwakadzama kwezvinhu, maitiro, uye kusangana kwechigadzirwa chekupedzisira nenharaunda. Kuzvipira uku ndiko kunovasiyanisa semutungamiri weindasitiri.
