Handizive kuti chii chinonzi "chinokatyamadzwa, chinoshambidzika?"
Ngatitaurei nezvekuvaka kutevedzana kwekutanga. Mafuta anokosha anofanirwa kuyerera mukati memaawa matanhatu mushure mekunge chigadziko cheshuwa chabviswa. Mafuta okusarongeka anoshandisa anokudzwa Asphalt PC-2. Mari yacho inogona kutsanangurwa nekuedzwa kwekupfirwa ku1.5 marita ekwere mita, uye kudzika kwepazasi hakuna kuderera 5mm. Mushure mekupfira mafuta anokosha emafuta, anoyeuka asphalt pc-1 yakaderera chisimbiso cheshuwa chakavezwa. Iyo huwandu hwemhedzisiro isphalt ndeye 1.0 liters pa mativi mita, iyo Aggregate size saizi iri 0.5 kusvika ku1CM, uye gobvu haifanire kunge isingasviki 0.6 cm. Asati avhara asphalt kongiri, iyo inonamatira mafuta anofanirwa kupfirwa pamatehwe epamusoro uye epasi eiyo yepasi yekuisa chisimbiso uye pamativi emvura, tsime remvura, kuongorora tsime uye zvimwe zvivakwa. Iyo yekuzvinamatira yemafuta emafuta anoshandisa inokonzeresa asphalt pc-3, ine dosage ye 0.5 liters pa mativi mita.

Chisimbiso cheSeal chinogona kukamurwa kuita chisimbiso chepamusoro chesale uye chivharo chakaderera chesal; Panyaya yemhando yekuvaka, iyo imwe-yakajeka-yekukara nzira yekuvhiringidza kana denderedzwa rekuvhara rinogona kushandiswa, kana emulsified asphalt inogona kushandiswa. Green Slurry Chisimbiso.
Munzvimbo dzekunaya uye dzakanyorova, iyo asphalt yekufambisa kwezviratidziro uye yekutanga-nzira migwagwa mikuru ine hupfumi hukuru uye ingangove yekutsvaga mvura zvakakomba. Kana kana iyo asphalt pamusoro peganda isingakwanisi kuiswa munguva panguva yekuvakwa kweiyo base layer uye mota dzinoda kupfuura, zvinokurudzirwa kuisa iyo yepazasi chisimbiso mushure mekupfira mafuta-emafuta.
Iyo yepazasi yeSeal layer yakaiswa pamusoro peiyo semi-yakaomeswa base yekuchengetedza motokari, dzivirira mvura yemvura pasi pechigadziko, uye simbisa kubatana pakati pehupamhi hwenzvimbo uye chigadziko cheshuwa. Kune akawanda mafambiro ekuvaka eiyo solive seal layer.
Iyo yepamusoro seal layer inofanira kuiswa pane asphalt pamusoro pejasi mumamiriro ezvinhu anotevera:
