Nezve matanho akakosha emhando yekuvaka asphalt pavement, Henan Sinoroader Heavy Industry Corporation inotsanangura imwe ruzivo:
1. Usati wavaka, ita bvunzo kutanga kuti usarudze kuti ndezvipi zvinhu uye zviyero zvekushandisa zvichibva pane hwaro chimiro mamiriro, uye wozoona kubatanidzwa kwega rega rega, pane-saiti man-muchina musanganiswa, kumhanya kwekutyaira uye zvimwe zvinodiwa kuburikidza nemugwagwa wekuyedza.
2. Iva nechokwadi chokuti nzvimbo yepasi yakachena uye yakaoma. Usati wadira mafuta anopinda mukati, unofanirwa kushandisa mhepo compressor kana moto wemusango kuti ufuridze guruva pamusoro pechigadziko chepasi (kana chigadziko chikasvibiswa zvakanyanya, iwe unofanirwa kutanga wariputira nepfuti yemvura inomanikidza. uye woifuridza ikachena kana yaoma). Edza kuchengetedza pamusoro pechigadziko chepasi chakachena. Iyo aggregate inoratidzwa, uye pamusoro peiyo base layer inofanira kunge yakaoma. Kunyorova kwechigadziko chepasi hakufanirwe kudarika 3% kufambisa kupinza kwemafuta anopinza uye kusungirirwa nehwaro hwepasi.
3. Sarudza midziyo yekuparadzira yakakodzera. Kusarudzwa kwemichina kwakakosha zvikuru. Parizvino, kune akawanda echinyakare marori anoparadzira marori muChina, zvichiita kuti zviome kuve nechokwadi chekuvaka. Rori yakafanira yemafuta ekuparadzira rori inofanirwa kuve neyakazvimirira pombi yemafuta, yekupfapfaidza nozzle, chiyero mita, pressure gauge, mita, thermometer kuverenga tembiricha yechinhu chiri mutangi remafuta, bubble level uye hose, uye kuve neine asphalt circulation kusanganisa. mudziyo, Midziyo iri pamusoro inofanira kunge iri muhurongwa hwakanaka hwekushanda.
4. Dzora kuwanda kwekupararira. Panguva yekuvaka, rori inopararira inofanira kuve nechokwadi kuti inomhanya nekumhanya kweyunifomu kuti ive nechokwadi cheyunifomu uye yakagadzikana kupararira huwandu. Kazhinji shandisa ndiro yesimbi kutarisa huwandu hwekupararira. Kana huwandu hwekupararira husingasviki nezvinodiwa, gadzirisa huwandu hwekupararira munguva nekushandura kumhanya kwekutyaira.
5. Mushure mokunge kupararira-kupararira kwapera, basa rekudzivirira rinofanira kuitwa. Nekuti mafuta anopinda anoda imwe tembiricha yekupararira uye nguva yekupinda. Kupararira tembiricha kazhinji kuri pakati pe80 ne90°C. Nguva yekupararira ndeye apo tembiricha yemasikati yakakwira zvakanyanya, tembiricha yepasi iri pakati pe55 ne65 ° C, uye asphalt iri munzvimbo yakapfava. Nguva yekupinda kweoiri inopinda mukati kazhinji maawa mashanu kusvika matanhatu. Munguva ino yenguva, traffic inofanirwa kudzorwa zvakanyanya kudzivirira kunamatira kana kutsvedza, izvo zvinozokanganisa mhedzisiro yemafuta anopindika.
Iyo asphalt permeable layer inoita basa risingadzokerike mune yese asphalt pavement yekuvaka maitiro. Imwe neimwe nzira yekuvaka uye yakabatana bvunzo, tembiricha, rolling uye zvimwe zviratidziro zvinodzorwa zvakanaka, uye kuvakwa kweiyo permeable layer ichapedzwa nenguva uye muhuwandu.
