Nekukurumidza kusimukira kweupfumi hwenyika yedu pamwe neruzivo rwemichina, mamiriro emumigwagwa yemunyika medu avandudzwawo zvikuru. Nekudaro, huwandu hwekuremerwa kwemotokari huri kuwedzerawo nekukurumidza, uye huwandu hwemarori makuru huri kuwedzera zvakare, izvo zvaunza kumanikidza kukuru kune zvekufambisa. Naizvozvo, mugwagwa mukuru Basa rekugadzirisa rakakwezva vanhu zvishoma nezvishoma.
Iyo yakarongwa yemigwagwa mikuru inoshandisa yakajairwa asphalt inosunga zvinhu, izvo zviri kure nekuzadzisa zviyero zvepamusoro uye zvinodiwa zvekufambisa kwemazuva ano kumigwagwa mikuru. Magadzirirwo epamusoro-giredhi pavement asphalt binder kuti ive nechokwadi chemhando uye kugona kwekushandiswa kwemugwagwa mukuru mubvunzo unofanirwa kuongororwa. Slurry sealing uye micro-surfacing tekinoroji iri kusimudzirwa zvishoma nezvishoma senzira dzekudzivirira dzekuchengetedza nemhando yakanaka uye mutengo wehupfumi.
Kuumbwa kwe emulsified asphalt slurry musanganiswa kwakaoma, kunyanya kusanganisira simenti, nhunzi ash, mineral powder uye additives. Musanganiswa weslurry unoshandisa dombo kana jecha sechinhu chakakosha, asi kusarudzwa kwedombo nejecha hakusi kupokana, asi kunofanirwa kusvika kune imwe gradation, uye wobva wawedzera chimwe chikamu cheasphalt sechinhu chinosunga kuti chiwane chinosunga. Kana mamiriro acho akakosha, iwe unogona zvakare kusarudza kuwedzera imwe chikamu chehupfu. Mushure mokunge zvinhu zvose zvawedzerwa, zvinosanganiswa nemvura mune imwe chikamu kuti zvigadzire asphalt musanganiswa. Iyo asphalt musanganiswa inoumbwa nezvikamu izvi inoyerera uye iri nyore kushandisa panguva yekugadzirisa mugwagwa. Musanganiswa unopfapfaidzwa pamusoro pemugwagwa nerori inovhara slurry kuita chisimbiso che slurry. Iwo makuru ehunyanzvi mapoinzi ekupfapfaidza anoenderera uye mayunifomu. Iko kusanganiswa kunoumba hutete hwakatsetseka hweasphalt pamusoro pekurapa pamusoro pemugwagwa, iyo inobatsira kune inotevera nzira. Basa guru reiyi nhete yakaonda ndeyekuchengetedza nzira yepakutanga uye kuderedza kupera kwemugwagwa.
Pamusana pekubatanidzwa kwechimwe chikamu chemvura mumusanganiswa wekuvhara slurry, zviri nyore kubuda mumhepo. Mushure mekunge mvura yaputika, inooma uye yakaoma. Nokudaro, mushure mokunge slurry yakaumbwa, haingotaridzi zvakanyanya kufanana neyakagadzirwa-grained asphalt concrete, asi haikanganisi kuonekwa kwemugwagwa. Iyo ine zvakare yakafanana tekinoroji zvimiro seyakakwenenzverwa kongiri maererano nekupfeka kuramba, anti-skid, kudzivirira mvura, uye kutsetseka. Slurry seal tekinoroji inoshandiswa mukugadzirisa mugwagwa mukuru nekuda kwehunyanzvi hwayo hwekuvaka, nguva pfupi yekuvaka, mutengo wakaderera, mhando yepamusoro, kushandiswa kwakakura, kuchinjika kwakasimba, nezvimwe. Iyo inzira yehupfumi uye inoshanda. Asphalt pavement kugadzirisa tekinoroji yakakodzera kushandiswa uye kusimudzirwa. Pamusoro pezvo, zvakanakira tekinoroji iyi zvinoratidzwawo musimba rekubatana kwepamusoro pakati peasphalt uye mineral materials, kusanganiswa kwakasimba nepamusoro pemugwagwa, kukwanisa kuvhara zvachose zvicherwa, simba guru uye kugara zvakanaka.
