Mazuvano, asphalt pavement inoshandiswa zvakanyanya mukuvaka migwagwa nekuda kwekuwanda kwayo kwakanakira. Parizvino, isu tinonyanya kushandisa inopisa asphalt uye emulsified asphalt mukuvaka asphalt pavement. Asphalt inopisa inoshandisa simba rekupisa rakawanda, kunyanya jecha rakawanda uye matombo anoda kubikwa, nzvimbo yekuvaka yevashandi haina kunaka, uye kusimba kwevashandi kwakakwira. Paunenge uchishandisa emulsified asphalt pakuvaka, haidi kupiswa, inogona kupfapfaidzwa kana kusanganiswa uye kupararira pane tembiricha yekamuri, uye zvimiro zvakasiyana-siyana zvepavement zvinogona kugadzirwa. Uyezve, emulsified asphalt inogona kuyerera yega patembiricha yekamuri, uye inogona kugadzirwa kuita emulsified asphalt yezvakasiyana zvekuisa zvinoenderana nezvinodiwa. Zviri nyore kuwana iyo inodiwa asphalt firimu ukobvu paunenge uchidira kana kupindira, izvo zvisingagoneke neasphalt inopisa. Nekuvandudzwa zvishoma nezvishoma kwemigwagwa yemigwagwa uye zvinodiwa zvekusimudzira zvemigwagwa yakaderera, kushandiswa kweasphalt emulsified kuchawedzera; nekusimudzirwa kwekuziva kwezvakatipoteredza uye kusimba zvishoma nezvishoma kwesimba, chikamu cheasphalt emulsified muasphalt chichawedzera, chiyero chekushandiswa chichave chakapamhama nekufara, uye kunaka kuchava nani uye nani. Emulsified asphalt haina chepfu, haina kunhuwa, isingabatike, inoomesa nekukurumidza, uye yakasimba kubatana. Haikwanise kungovandudza kunaka kwemugwagwa, kuwedzera chiyero chekushandiswa kweasphalt, kuwedzera mwaka wekuvaka, kuderedza kusvibiswa kwezvakatipoteredza, nekuvandudza mamiriro ekuvaka, asiwo kuchengetedza simba nezvinhu.

Emulsified asphalt inonyanya kuumbwa neasphalt, emulsifier, stabilizer uye mvura.
1. Asphalt ndicho chinhu chikuru che emulsified asphalt. Unhu hweasphalt hunoenderana zvakananga nekushanda kwe emulsified asphalt.
2. Emulsifier ndicho chinhu chakakosha pakuumbwa kweasphalt emulsified, iyo inosarudza kunaka kweasphalt emulsified.
3. Stabilizer inogona kuita emulsified asphalt ine yakanaka yekuchengetedza kugadzikana panguva yekuvaka maitiro.
4. Kazhinji, hutano hwemvura hahuna kunyanya kuoma uye haifaniri kunge iine humwe hutsvina. Iyo pH kukosha kwemvura uye calcium uye magnesium ion ine mhedzisiro pa emulsification.
Zvichienderana nemidziyo uye emulsifiers inoshandiswa, kuita uye kushandiswa kweasphalt emulsified kwakasiyanawo. Anowanzo shandiswa ndeaya: akajairwa emulsified asphalt, SBS yakagadziridzwa emulsified asphalt, SBR yakagadziridzwa emulsified asphalt, super inononoka kupwanya emulsified asphalt, yakakwirira permeability emulsified asphalt, yakakwira concentration uye yakakwirira viscosity emulsified asphalt. Saizvozvo, madhipatimendi anoona nezvemigwagwa anofanirwa kutarisisa nyaya dzekugadzirisa migwagwa, kudzivirira pamwe nekuderedza zvirwere zvakasiyana-siyana zvemumigwagwa, kuitira kuti migwagwa yedu ive yemhando yepamusoro.
