Ukutywinwa kwe-Slurry kusebenzisa izixhobo zoomatshini ukuxuba i-asphalt edidiyelwe ngokufanelekileyo, i-asphalt esemgangathweni kunye ne-aggregates efanelekileyo, amanzi, izihluzi (isamente, ikalika, uthuthu lwempukane, umgubo wamatye, njl.njl.) kunye nezongezo ngokomlinganiselo oyilelweyo kumxube we-slurry kwaye ngokufanayo Igayiwe. kumphezulu wendlela yantlandlolo kwaye kudityaniswe ngokuqinileyo nomphezulu wendlela yantlandlolo ngeenkqubo zokugquma, ukususwa kwemulsification, ukwahlulwa kwamanzi, ukuguquka komhlaba ube ngumphunga kunye nokuqina ukwenza itywina elishinyeneyo, elinamandla, elingagugiyo neliphucula kakhulu ukusebenza komgangatho wendlela. umphezulu wendlela.
Itekhnoloji yokutywinwa kwe-slurry yavela eJamani ngasekupheleni kweminyaka yoo-1940. EUnited States, ukusetyenziswa kwe-slurry sealant kubala i-60% yendlela yabamnyama yelizwe, kwaye ububanzi bokusetyenziswa kwayo kwandisiwe. Idlala indima ekuthinteleni nasekulungiseni izifo ezifana nokuguga, iintanda, ukuguda, ukuxenga, kunye nemingxuma kwiipavumente ezintsha nezindala, ukwenza Iipropati ezingangeni manzi, ezichasene nokutyibilika, ezigudileyo kunye nezingagugiyo kumphezulu wendlela ziphuculwa ngokukhawuleza.
Ukutywinwa koludaka kukwayindlela yokwakha ekhuselayo yokulungiswa komphezulu wepavumente. Iipavumente zeasphalt ezindala zihlala zineentanda kunye nemingxuma. Xa umphezulu ugugile, umxube wokutywinwa we-asphalt slurry emulsified usasazwa kwi-pavement ibe ngumaleko obhityileyo kwaye uvumeleke ukuba uqiniswe ngokukhawuleza, ukuze i-asphalt ikhonkrithi i-pavement igcinwe. Kukugcinwa kunye nokulungiswa ngenjongo yokubuyisela umsebenzi wendawo yendlela kunye nokuthintela umonakalo omkhulu.

Ukuqhekeka okucothayo okanye okuphakathi kokuqhekeka okuxubeneyo kwe-asphalt e-emulsified esetyenziswe kwi-slurry seal layer ifuna ukuba i-asphalt okanye umxholo we-asphalt we-polymer ube malunga ne-60%, kwaye ubuncinane kufuneka bungabi ngaphantsi kwe-55%. Ngokuqhelekileyo, i-asphalt ye-anionic emulsified inokubambelela kakubi kwizinto zamaminerali kwaye ithatha ixesha elide ukwenza. Isetyenziswa kakhulu kwi-alkaline aggregates, njenge-limestone. I-asphalt ye-Cationic emulsified ine-adhesion efanelekileyo kwi-acidic aggregates kwaye isetyenziswa kakhulu kwii-acidic aggregates, ezifana ne-basalt, igranite, njl.
Ukukhethwa kwe-asphalt emulsifier, enye yezithako kwi-asphalt e-emulsified, ibaluleke kakhulu. I-asphalt emulsifier efanelekileyo ayinakuqinisekisa kuphela umgangatho wokwakha kodwa nokugcina iindleko. Xa ukhetha, unokubhekisela kwiimpawu ezahlukahlukeneyo ze-asphalt emulsifiers kunye nemiyalelo yokusetyenziswa kweemveliso ezihambelanayo. Inkampani yethu ivelisa iintlobo ngeentlobo zee-asphalt emulsifiers ezineenjongo ezininzi. Ukuba unayo nayiphi na imibuzo, nceda uqhagamshelane nenkonzo yethu yabathengi.
I-emulsified asphalt slurry seal ingasetyenziselwa ukugcinwa kothintelo lweKlasi ye-II kunye noohola bendlela engaphantsi, kwaye ifanelekile kumaleko wetywina esezantsi, enxibe umaleko okanye umaleko okhuselayo weendlela ezintsha. Ngoku ikwasetyenziswa koohola bendlela.
Ukuhlelwa kweetywina ezinodaka:
Ngokomgangatho wezimbiwa
Ngokwemigangatho eyahlukeneyo yezinto zamaminerali, umaleko wokutywina we-slurry unokwahlulwa ube umaleko wokutywina ocolekileyo, umaleko wokutywina ophakathi kunye nomgangatho wokutywina orhabaxa, omelwe yi-ES-1, ES-2 kunye ne-ES-3 ngokulandelelanayo.
Ngokwesantya sokuvula kwi-traffic
Ngokwesantya sokuvula i-traffic[1], izitywina eziludaka zinokwahlulwa zibe zitywina ezivula ngokukhawuleza ze-traffic slurry kunye nokuvula okucothayo kwezitywina ze-traffic slurry.
Ukwahlulwe ngokweemodyuli zepolymer zongezwa
Ngokubhekiselele ekubeni isilungisi sepolymer songeziwe, umaleko wokutywina unodaka unokwahlulwa ube umaleko wokutywina oludaka kunye nomaleko wokutywina olungisiweyo.
Ukwahlulwe ngokweempawu ezahlukeneyo ze-asphalt e-emulsified
Umaleko wokutywina we-slurry wahlulahlulwe waba ngumaleko wokutywina oqhelekileyo kunye nohlengahlengiso lokutywinwa komgangatho wokutywina ngokweempawu ezahlukeneyo ze-asphalt e-emulsified.
Yahlulwe ngokobunzima
Ngokobunzima obahlukeneyo, yahlulahlulwe yaba ngumaleko wokutywina ocolekileyo (I umaleko), umaleko wokutywina ophakathi (uhlobo lwe-II), umaleko orhabaxa wokutywina (uhlobo lwe-III) kunye nomgangatho wokutywina (uhlobo lwe-IV).
