I-Micro-surfacing iteknoloji yokukhusela yokukhusela esebenzisa ibakala elithile leetshiphu zamatye okanye isanti, iifayili (i-samente, i-lime, i-fly ash, i-stone powder, njl.) kunye ne-polymer-modified emulsified asphalt, i-admixtures yangaphandle kunye namanzi ngomlinganiselo othile. Yixube kumxube ohambayo kwaye emva koko usasaze ngokulinganayo phezu komgangatho wokutywina kwindlela.
Uhlalutyo lwesakhiwo sendlela kunye nezizathu zezifo zendlela
(1) Ukulawulwa komgangatho wempahla ekrwada
Ngexesha lenkqubo yokwakha, ukulawulwa kwezinto eziluhlaza (i-coarse aggregate diabase, i-fine aggregate diabase powder, i-asphalt e-emulsified emulsified) iqala ngezinto zokungena ezinikezelwe ngumthengisi, ngoko ke izinto ezibonelelwe ngumthengisi kufuneka kubekho ingxelo yovavanyo olusemthethweni. Ngaphezu koko, izixhobo zihlolwa ngokubanzi ngokuhambelana nemigangatho efanelekileyo. Ngexesha lenkqubo yokwakha, umgangatho wezinto eziluhlaza kufuneka kwakhona uhlalutywe. Ukuba kukho nakuphi na ukuthandabuza, umgangatho kufuneka uhlolwe ngokungenamkhethe. Ukongeza, ukuba utshintsho kwizinto eziluhlaza zifunyenwe, izinto ezithunyelwa ngaphandle kufuneka zihlolwe kwakhona.
(2) Ukulawulwa kokuhambelana kwe-slurry
Kwinkqubo yokulinganisa, ukuyila kwamanzi omxube we-slurry kunqunywe. Nangona kunjalo, ngokwempembelelo yokufuma kwisiza, ukufuma kwe-aggregate, iqondo lobushushu lokusingqongileyo, ukufuma kwendlela, njl. Ubungakanani bamanzi asetyenzisiweyo kumxube wodaka luhlengahlengiswa kancinane ukuze kugcinwe ukuhambelana komxube olungele iimfuno zokugalela indledlana.
(3) Ulawulo lwexesha leMicro-surface demulsification
Ngexesha lenkqubo yokwakhiwa kwe-micro-surfacing ye-highway, isizathu esibalulekileyo seengxaki zomgangatho kukuba ixesha lokuchithwa komxube we-slurry lisekude kakhulu.
Ubukhulu obungalinganiyo, imikrwelo, kunye nokungavisisani kwe-asphalt okubangelwa kukukhupha iimulsification zonke zibangelwa kukususwa kwangaphambi kwexesha. Ngokubhekiselele kwibhondi phakathi kwendawo yokutywina kunye nomgangatho wendlela, ukuchithwa kwangaphambi kwexesha kuya kuba yingozi kakhulu kuyo.
Ukuba kufunyaniswe ukuba umxube uhlanjululwe ngaphambi kwexesha, umlinganiselo ofanelekileyo we-retarder kufuneka wongezwe ukutshintsha i-dosage ye-filler. Kwaye uvule iswitshi yamanzi esele imanzi ngaphambili ukulawula ixesha lokwaphuka.
(4) Ukulawulwa kokwahlula
Ngexesha lenkqubo yokugayilwa koohola bendlela, ulwahlulo lwenzeka ngenxa yezizathu ezinjengobungqingqwa obucekethekileyo bokugada, udidi lomxube oshinyeneyo, kunye nokuma komgca wokumakisha (ogudileyo kunye nobukhulu obuthile).
Ngethuba lenkqubo yokukhwela, kuyimfuneko ukulawula ubuninzi be-paving, ukulinganisa ubuninzi be-paving ngexesha, kwaye wenze uhlengahlengiso ngexesha elifanelekileyo ukuba kukho naziphi na iintsilelo. Ukuba i-gradation yomxube inqabileyo kakhulu, ukuhlanjululwa komxube we-slurry kufuneka kuhlengahlengiswe ngaphakathi kwinqanaba lokuhlengahlengiswa ukuze kuphuculwe into yokwahlula kwi-micro surface. Kwangaxeshanye, iimpawu zendlela eziza kugalelwa kufuneka zicolwe phambi kokuba kugaywe.
(5) Ukulawulwa kobungqingqwa bokuhamba kwendlela
Kwinkqubo yokupakisha yeendlela ezihamba phambili, ubukhulu be-paving yomxube omncinci malunga ne-0.95 ukuya kwi-1.25 amaxesha. Kuluhlu lokuhlelwa, ijika kufuneka libe kufutshane necala elinzima.
Xa umlinganiselo wee-aggregates ezinkulu kwi-aggregate inkulu, kufuneka ibekwe ngokugqithiseleyo, ngaphandle koko i-aggregates enkulu ayinakunyanzeliswa kwinqanaba lokutywina. Ngaphezu koko, kulula ukubangela imikrwelo kwi-scraper.
Ngokuchasene noko, ukuba iaggregate ilungile ngexesha lenkqubo yolungelelwaniso, ngoko ke indlela egangathiweyo kufuneka igayiwe ibe mncinci ngexesha lenkqubo yokupakisha uhola wendlela.
Ngexesha lenkqubo yolwakhiwo, ubukhulu bepaving kufuneka bulawuleke kwaye buvavanywe ukuqinisekisa ubungakanani bomxube wodaka olusetyenziswa kuhola wendlela. Ukongeza, ngexesha lokuhlolwa, i-vernier caliper ingasetyenziselwa ukulinganisa ngokuthe ngqo i-slurry seal kwi-micro-surface yohola wendlela esanda kugalelwa. Ukuba idlula ubukhulu obuthile, ibhokisi yepaver kufuneka ilungiswe.
(6) Ukulawulwa kokubonakala kohola wendlela
Ukulungiselela i-micro-surface paving kuhola wendlela, amandla esakhiwo somphezulu wendlela kufuneka avavanywe kwangaphambili. Ukuba ukuxengalala, amaza, ubuthathaka, imingxuma, uludaka, neentanda ziyavela, ezi meko zendlela kufuneka zilungiswe ngaphambi kokuba kutywinwe ukwakhiwa.
Ngexesha lokuhamba, qiniseka ukuba uyigcina ngokuthe tye kwaye uqinisekise ukuba i-curbs okanye iindlela zendlela zihambelana. Ukongeza, xa ugaqa, ububanzi bokuhamba kufuneka buqinisekiswe, kwaye amajoyina kufuneka abekwe kangangoko kunokwenzeka kumgca wokwahlula umgca ukulawula ukuzinza kokuxuba kunye nokuthintela izinto zokwahlula kwangaphambili kwibhokisi yokupakisha ukuqinisekisa ukuba zi Umthamo wamanzi ngexesha lenkqubo ulungelelene kwaye uphakathi.
Ukongezelela, zonke izinto kufuneka zihlolwe ngexesha lokulayishwa ukuze zisuse iinqununu ezigqithisiweyo, kwaye iziphene kufuneka zilungiswe ngexesha ngexesha lokuzaliswa ukuze zigcine ukubonakala kwazo zihamba kakuhle kwaye zihambelana.
(7) Ukulawulwa kokuvuleka kwezithuthi
Uvavanyo lwamanqaku esihlangu yindlela eqhele ukusetyenziswa yokuhlola umgangatho wokuvula uhola wendlela ngexesha lokugcinwa kohola wendlela omncinci. Oko kukuthi, beka ubunzima bomntu kwingcambu okanye ezantsi kwesihlangu kwaye ume kwindawo yokutywina imizuzwana emibini. Ukuba i-aggregate ayikhutshwanga okanye incamathele kwisihlangu somntu xa ishiya indawo yokutywina, inokuthathwa njengomgangatho omncinci. Emva kokuba umsebenzi wokulondoloza ugqityiwe, unokuvulwa kwi-traffic.
