Itekhnoloji ye-synchronous gravel yokutywinwa isetyenziswe ngokuthe ngcembe ekhaya nakwamanye amazwe. Bubuchwephesha obunoqoqosho kunye nokugcinwa ngokufanelekileyo. Iloli yokutywina ye-synchronous gravel isetyenziselwa ukusasaza i-asphalt binder (i-asphalt elungisiweyo, i-asphalt emulsified, njl.) kunye namatye obungakanani beqhekeza elinye (elihlala lisetyenziswa kwi-4 ukuya kwi-6 mm, 6 ukuya kwi-10 mm) kumphezulu wendlela ngaxeshanye, kwaye emva koko udlule. umatshini wokuqengqeleka kwamatayara erabha Okanye ukuqengqeleka kwendalo kwezithuthi kwenza umaleko wokunxiba wepavement ye-asphalt yegrabile. Inokulungisa iintanda zendlela, inciphise iintanda ezibonisa indlela yendlela, kwaye iphucule ukuguga. Ifilimu ye-asphalt eyenziwe kwindlela yomgwaqo ingakwazi ukumelana nokungena kwamanzi angaphezulu. Inexesha elifutshane lokwakha, iteknoloji elula, kunye nokusebenza okunamandla. Okwangoku, umaleko we-synchronous gravel seal isetyenziswa kugcino lothintelo koohola bendlela, oohola beendlela eziqhelekileyo, iindlela zedolophu nezelokishi, kwaye zingasetyenziswa kwisiseko sokunxiba umaleko weendlela ezintsha kunye nomaleko wetywina osezantsi wemigangatho yendlela eyomeleziweyo. Xa iimali zokwakha zixinene, zinokusetyenziswa njengendlela yenguqu koohola bendlela abakumgangatho ophantsi.
Ngexesha lenkqubo ethile yokwakha, le teknoloji igxile kakhulu kumaleko angaphezulu, ngelixa umgca wokutywina ophezulu kunye nomgangatho wokunxiba zihlala zingahoywa, okukhokelela ekulahlekeni kwezixhobo. Kwiminyaka yakutshanje, iitekhnoloji ezifana ne-micro-surfacing kunye ne-ultrasonic abrasion ziye zaqhubeka zivela. Kwinkqubo yokukhusela ukukhusela iindlela ze-asphalt, iteknoloji yokutywina isoloko isetyenziswa. Ubuchwephesha obusetyenziswa ngokuqhelekileyo bubandakanya ukugquma okushushu kunye nokubanda okubhityileyo kunye nokutywinwa kokuqhekeka. iileya kunye nezinye iintlobo ezininzi. Olona khetho luphambili lwetekhnoloji yokutywina yomaleko wokuhamba nge-asphalt ngumaleko wokutywina we-asphalt ngaxeshanye. Le teknoloji inokugcina ngokufanelekileyo iindleko zeprojekthi. Ukongezelela, ekubeni obu bugcisa babusetyenziswa eFransi ekupheleni kwenkulungwane yama-20, buye banda ngokukhawuleza ukuya kutsho eUnited States naseYurophu. Amazwe, kuquka ambalwa aseAsia, eAfrika naseOstreliya, nawo aqalisile ukusebenzisa obu bugcisa kwiiprojekthi ezithile. Izibalo zibonisa ukuba kuphela malunga ne-5% yeeprojekthi eYurophu ayisebenzisi le teknoloji yokukhusela ukugcinwa kweendlela. Okwangoku, xa usebenzisa le teknoloji yokutywinwa kwilizwe lethu, ezi mfuno zilandelayo kufuneka zifezekiswe.
(1) Iimfuno ezidityanisiweyo. Ukuze ukwazi ukuxhathisa ukuguga kunye nokukrazuka kwezithuthi ngexesha lokusebenza kohola wendlela, iiaggregates zepavumente kufuneka zibe nobunzima obaneleyo. Ngokukodwa kwimeko yokuhamba kwetrafikhi enzima kunye nomthwalo wesithuthi, ukukhethwa kobunzima obudibeneyo buba bukhulu ngakumbi; I-gradation ayiqhelekanga ukuxutywa nomgubo. Sebenzisa uhlobo olunye lohlelo; xa ukhetha i-aggregates, ukwenzela ukukhusela ukubonakala kweentlobo ze-pin-flake, sebenzisa i-cubic shape ukuze uqinisekise ukufakwa ngokupheleleyo kwee-aggregates kwi-asphalt.
(2) I-asphalt. Ukukhethwa kwe-asphalt kufuneka kuqala kuhlangabezane neemfuno ezifanelekileyo zokhetho lwe-asphalt olusetwe lisebe lohola wendlela. Ngokwesiseko sokuhlangabezana nemigaqo, i-emulsified, modified, irabha, okanye iasphalt yepetroleum eqhelekileyo inokukhethwa.
(3) Ukusetyenziswa kwezinto eziphathekayo. Xa usebenzisa iteknoloji yokutywina i-gravel yokugcinwa kwendlela, amatye kufuneka adibaniswe ngokuqinileyo, kwaye ilitye kufuneka ligutyungelwe ngokupheleleyo nge-asphalt ukuxhathisa ukugqoka kunye nokukrazula kwindlela ehamba ngayo ngamavili. Emva kokuba isixa esisasazekayo sininzi, i-asphalt binder iya kucinywa ngaphandle kwezithuba zamatye xa isithuthi sihamba phezu kwendlela, kwaye i-oil surface iya kubonakala, ngaloo ndlela inciphisa i-anti-skid kunye ne-friction index yendlela; Noko ke, ukuba ubungakanani bamatye buncinane kakhulu, amatye akanako ukubotshelelwa ngokufanelekileyo, aze amatye aphoswe ngaphandle kwendlela.
Isishwankathelo, ukusetyenziswa kwetekhnoloji yokutywinwa kwe-asphalt ngaxeshanye kunefuthe elibaluleke kakhulu. Akunakuthintela kuphela ngokufanelekileyo ukuqokelela kwamanzi endleleni, ukuphucula amandla okucheba kwendlela, kodwa kunye nokuphucula ngokufanelekileyo ukusebenza kwendlela phantsi kweemeko eziphantsi kunye neziphezulu zokushisa. Ukumelana nokuqhekeka okuphezulu kunokukhusela indawo ye-asphalt ukusuka ekukhukulisekeni okanye ekuqhekekeni. Le teknoloji isasaza i-asphalt eguquliweyo kunye nelitye elithobelayo ngokulinganayo kwindlela yomgwaqo ngaxeshanye ukuqinisekisa ukudibanisa okusebenzayo phakathi kwezi zibini kunye nokuphucula ukunamathela kunye namandla phakathi kwezi zibini. Ukongeza, le teknoloji ifanelekile, igcina izixhobo kunye neendleko, kwaye inokwenzeka okunamandla. Ngexesha elifanayo, ngenxa yeemfuno eziphezulu zezixhobo ezinxulumeneyo, iindleko zabasebenzi ziyancipha kakhulu. Ke ngoko, le ndlela yobugcisa inokunyuswa ukuba iphucule ukuxhathisa kokuqhekeka kunye nokusebenza okuchasene nokutyibilika kweendlela ze-asphalt kangangoko kunokwenzeka.
