Isici sobugcisa beteknoloji yokutywinwa kwe-gravel ngexesha elinye kukuba esinye isixhobo sinokusasaza izinto ezibophezelayo kunye nelitye ngaxeshanye. I-asphalt kunye nelitye kufuneka zidityaniswe kwisekondi enye. Ukushisa kwe-asphalt eshushu yi-140 ° C xa i-bonding material ifafazwa, kwaye iqondo lokushisa linokuqinisekiswa ukuba lingaphezulu kwe-120 ° C ngexesha lokudibanisa. Ubushushu be-asphalt behla kancinci kakhulu. Ngeli xesha, i-fluidity ye-asphalt binder isalungile kakhulu, kwaye indawo yokudibanisa kunye nelitye inkulu, eyandisa ukudibanisa kunye nelitye. Ukomelela kwebhondi yamatye. Ubuchwephesha bokutywinwa komphezulu bendabuko busebenzisa izixhobo ezibini ezahlukeneyo kunye neenkqubo ezimbini zokusasaza ukwakhiwa. Ixesha elide elinjalo lokwakha liya kubangela ukuba ubushushu be-asphalt buyehle malunga ne-70 ° C, kwaye umphumo wokudibanisa phakathi kwelitye kunye ne-asphalt uya kuba mbi, okukhokelela ekulahlekeni okukhulu kwamatye kunye nokuchaphazela ukusebenza komgca wokutywina. .
Itekhnoloji yokutywinwa kwegrabile ye-synchronous inezi mpawu zilandelayo:
(1) Ukukhusela amanzi ngcono. Ukutshizwa ngaxeshanye kwezinto ezibophelelayo kumqolo wegravel seal kungazalisa iintanda ezingephi kumphezulu wendlela, kuncitshiswe ukuqhekeka okubonakalayo kumphezulu wendlela, kwaye kwandise ukumelana nokuqhekeka komphezulu wendlela, ngaloo ndlela kuphuculwe ukusebenza kwe-anti-seepage yendlela. umphezulu.
(2) Ukubambelela kakuhle kunye neempawu ezichasayo. I-asphalt okanye ezinye izinto ezibophelelayo zibophelela iaggregate kumphezulu wendlela wokuqala. I-1/3 ye-aggregate inokuqhagamshelana ngqo namatayara. Ubunzima bayo kwandisa i-coefficient ye-friction kunye namathayi, ukuphucula ukunamathela kunye nokubambelela kwindlela yomgwaqo. Ukumelana nokutyibilika.
(3) Gqoka ukuxhathisa kunye nokuqina. Igrabile kunye ne-asphalt isasazeka ngaxeshanye yenza i-asphalt binder, kwaye i-2/3 yokuphakama kweengqungquthela zegrabile iyancipha kwi-asphalt, eyandisa indawo yoqhagamshelwano phakathi kwezi zibini, kunye ne-concave surface inokwakheka ngenxa yomtsalane omkhulu. amandla e-asphalt binder. Idityaniswe ngokusondeleyo kunye negrabile ukukhusela ukulahleka kwegrabile, ngoko ke i-synchronous gravel seal inokumelana nokunxiba kakuhle kunye nokuqina. Oku kukwangomnye wemiba ebalulekileyo yeteknoloji yokutywinwa kwegrabile ehambelanayo ukwandisa ubomi benkonzo yeendlela.
(4) Uqoqosho. Ukusebenza kweendleko zokutywinwa kwegrabile ngaxeshanye kubhetele kakhulu kunezinye iindlela zokucocwa komphezulu wendlela, ngaloo ndlela kuncitshiswa kakhulu iindleko zokugcinwa kwendlela.
(5) Inkqubo yokwakha ilula, isantya sokwakha siyakhawuleza, kwaye izithuthi zinokuvulwa ngexesha.
