Yabelana:
1. Uluhlu lwesiseko kufuneka lucocwe ukuze kuqinisekiswe ukuba umgangatho ophezulu womgangatho wesiseko ucocekile kwaye akukho qoqo lamanzi ngaphambi kokuba uqalise ukwakhiwa kweoli ye-permeable. Ngaphambi kokuhamba ngeoli evuzayo, kufuneka kuhlawulwe ingqalelo ekuphawuleni iindawo eziqhekezayo zoluhlu lwesiseko (i-fiberglass gratings inokubekwa ukuze kuncitshiswe ingozi efihlakeleyo yokuqhekeka kwe-asphalt pavement kwixesha elizayo).
2. Xa usasaza ioli ye- through-layer , ingqalelo kufuneka ihlawulwe kwii-curbs kunye nezinye iindawo ngokuqhagamshelana ngokuthe ngqo ne-asphalt. Oku kufuneka kuthintele amanzi ekungeneni kwinqanaba elingaphantsi kwaye lonakalise umgangatho ongaphantsi, obangela ukuba i-pavumente izike.
3. Ubukhulu bomaleko we-slurry seal kufuneka ilawulwe xa uyivula. Akufunekanga ibe ngqindilili kakhulu okanye ibhitye kakhulu. Ukuba kukhulu kakhulu, kuya kuba nzima ukuphula i-asphalt emulsification kwaye kubangele iingxaki ezithile zomgangatho.
4. Ukuxuba i-asphalt: Ukuxuba i-asphalt kufuneka kuxhotyiswe ngabasebenzi bexesha elizeleyo ukulawula ukushisa, ukuxuba umlinganiselo, umlinganiselo we-oil-stone, njl njl.

5. Ukuthuthwa kwe-asphalt: Iinqwelo zezithuthi zokuthutha kufuneka zidwetshwe nge-anti-adhesive agent okanye i-agent ehlala yedwa, kwaye kufuneka ifakwe kwi-tarpaulin ukuze ifezekise indima yokufakelwa kwe-asphalt. Ngexesha elifanayo, izithuthi ezifunekayo kufuneka zibalwe ngokubanzi ngokusekelwe kumgama ukusuka kwisikhululo se-asphalt ukuya kwindawo yokupakisha ukuze kuqinisekiswe ukusebenza okuqhubekayo kwe-asphalt.
6. I-asphalt paving: Ngaphambi kokuhamba nge-asphalt, i-paver kufuneka ifudunyezwe i-0.5-1 yeyure kwangaphambili, kwaye i-paving inokuqaliswa ngaphambi kokuba iqondo lokushisa libe ngaphezu kwe-100 ° C. Imali yokuqalisa ukupeyinta kufuneka iqinisekise umsebenzi wokuseta, umqhubi wepaver, kunye nokupeyintwa. Umsebenzi we-paving unokuqala kuphela emva kokuba umntu ozinikeleyo kumatshini kunye nebhodi yekhompyutheni kunye ne-3-5 iilori zothutho eziphathekayo zikhona. Ngethuba lenkqubo yokukhwela, izinto kufuneka zizaliswe ngexesha leendawo apho i-mechanical paving ingekho, kwaye inqatshelwe ngokungqongqo ukulahla izinto.
7. Ukudityaniswa kwe-asphalt: Iirola zamavili entsimbi, iirola zamatayara, njl. njl. zingasetyenziselwa ukuhlanganisa ikhonkrithi ye-asphalt eqhelekileyo. Iqondo lobushushu lokuqala elicinezelayo aliyi kuba ngaphantsi kwe-135 ° C kwaye iqondo lokugqibela elicinezelayo aliyi kuba ngaphantsi kwe-70 ° C. I-asphalt elungisiweyo ayiyi kuxutywa ngeerola zamatayara. Iqondo lobushushu lokuqala elicinezelayo aliyi kuba ngaphantsi kwama-70°C. Akukho ngaphantsi kwe-150 ℃, iqondo lobushushu lokugqibela alikho ngaphantsi kwe-90 ℃. Kwiindawo ezingenako ukutyunyuzwa ngama-roller amakhulu, ii-roller ezincinci okanye i-tampers zingasetyenziselwa ukuxinzelela.
8. Ukugcinwa kwe-asphalt okanye ukuvulela izithuthi:
Emva kokuba i-asphalt paving igqityiwe, ngokomgaqo, ukugcinwa kuyadingeka kwiiyure ze-24 ngaphambi kokuba ivulwe kwi-traffic. Ukuba kuyimfuneko ngenene ukuvula izithuthi kwangaphambili, unokufefa amanzi ukuze uphole, kwaye izithuthi zinokuvulwa emva kokuba iqondo lobushushu lehle ngaphantsi kwe-50°C.
