Nezve permeable yakagadziridzwa asphalt pavement yakadzama kunzwisisa
Semugadziri wehunyanzvi Sinoroader, tinokupa iwe nzira inopindika yeasphalt yeasphalt, inova iyo huru aggregate mukutanga compaction, kupfapfaidza emulsion layer mushure mekupararira, kumwaya emulsion, uye compacting iyo pavement chimiro nhanho nhanho. Inokodzera migwagwa yechipiri neyechipiri, uye inogona zvakare kushandiswa seyekubatanidza layer yeasphalt pavement kana base.
Nekuda kwehukuru porosity yeiyo emulsified asphalt tsono yemhando yekupinda, iyo yepamusoro iri nyore kupinda mukati, saka iyo paving zvinhu uye chisimbiso zvinhu kana layer inofanira kuiswa. Zvakadai sekugadzira semi-rigid base, sechisimbiso layer. Kana ichishandiswa sechisungo chekubatanidza, zvinhu uye pamusoro hazvigoni kuiswa chisimbiso.
Emulsified asphalt penetration type ndiyo sarudzo yekuvaka mumwaka wakaoma uye unopisa. Inofanira kunge iri mumwaka wekunaya kwemvura, hafu yemwedzi tembiricha yepamusoro isati yadzikira pane 15 ℃, saka inogona kubaiwa kuburikidza neyakavhurika chimiro layer inoyerera kudhiraivha ichikunguruka, yakanyatso kuumbwa mwaka usati wasvika.
Emulsified asphalt permeable aggregate inofanira kusarudzwa pakona, yakasvinwa yakaoma rock embedment, uye kana matombo aputsika, nzvimbo yekupwanya inopfuura 40%. Saizi yehukuru hweiyo main layer permeability haisi pasi pe50% yehuwandu hwehuwandu. Hapana pamusoro pemusanganiswa wepamusoro permeable emulsified asphalt mhando, pakupera kwekuvaka, yega yega 1000㎡ mugwagwa wepamusoro unofanirwa kuve imwe 2 ~ 3 cubic metres, yakaunganidzwa yakaunganidzwa mushure mechikamu chekuisa chisimbiso chine zvakangofanana, kurapwa kwekutanga.
