Iyo imhando yeasphalt inopikisa deformation, yakakodzera kumigwagwa ine traffic inorema. Yakashandiswa mumapurojekiti enhandare yendege mumakore achangopfuura. Stone Mastic Asphalt (SMA) musanganiswa unopisa weasphalt une 70-80% coarse aggregate, 20-30% yakanaka aggregate uye 6-7% yakakwirira bhitumeni. Yakagadzirwa muGermany kuma1960 uye yakatanga kushandiswa muKiel, Germany.
Nekuda kweiyo coarse aggregate kuve dense mumusanganiswa, mikaha inoitika pakati peaggregates. Aya mapeji akazadzwa nemastic mortar (yakanaka aggregate, filler, polymer modified bitumen, cellulosic fiber).
CONDITIONS OF PRODUCTION
Bhitumeni nemamineral aggregate zvinofanira kupiswa patembiricha shoma ye175 °C (madhigirii) uye inodarika 190 °C (madhigirii).
Chirimwa: Inofanirwa kuve nemidziyo yekungodyisa iyo fiber yekuwedzera uye yekuzadza zvinhu pahuremu hwakatarisirwa.
Musanganiswa wakagadzirwa unopisa unofanirwa kuchengetwa mune inopisa asphalt bunker nekupisa uye kuvhara.
Kubata musanganiswa mune inopisa asphalt bunker inofanira kunge iri mukati meimwe nguva.
Kana musanganiswa unopisa waunzwa pavheji, tembiricha yemhepo inofanira kunge iri pasi pe10 °C uye tembiricha yemusanganiswa inofanira kunge iri pasi pe170°C.
Nekuda kwehuwandu hukuru hwehupamhi hwehupamhi (yakasara paNo.4 skrini) mumisanganiswa dhizaini, mutoro wekutakura wakakwira kupfuura dense graded bituminous asphalt sezvo kusangana kwedombo nedombo kunowedzera.
Kazhinji, basalt kana mamwe aggregates ane yakakwira silica yemukati anoshandiswa, saka abrasion kuramba yakakwira.
Zvidzidzo zvinoratidza kuti SMA inobudirira kupfuura bituminous asphalt maererano nekuumbwa kwepasi uye kutsvedza kuramba.
Sezvo iine bhitumini yakagadziridzwa kupfuura bituminous asphalt, inonyanya kurwisana nekuputika kwemafuta.
Saizvozvo, ine yakakwirira kurwisa kurwisa kuneta makatsemuka.
Inopa yakanyarara uye yakasununguka kutyaira nekuda kweiyo mastic chimiro.
Fiber additive unit inoshanda pakugadzirwa kwematombo mastic asphalt
Simba asphalt zvinomera zvakagadzirirwa kugadzirwa kwematombo mastic asphalt uye isu tine module mune yedu software system.Also isu tinogadzira cellulose dosing unit.Nevashandi vedu vane ruzivo, isu hatipei chete kutengesa kwemiti, asiwo mushure mekutengesa kushanda kwekutsigira uye kudzidziswa kwevashandi.
