phula kusakaniza malo, monga chida chomwe chimagwiritsidwa ntchito pokonza, kuphatikizapo phula la mapistel, ndi misewu yamatawuni ndi ndege. Ntchito yake yogwirizana ndiyo kukwaniritsa molondola, kusakaniza koyenera komanso kusakaniza kosasakaniza kwa phulat./3/. Kuphatikizika kwa phula kusakaniza Station Station / / ... Zipangizozi zimagwirira ntchito limodzi kuti zigwirizanenso molondola, kusakaniza bwino komanso kusakaniza kosakanikirana kwa ntchito zomangamanga monga misewu yayikulu, ma races a ndege.

Patsamba la lero zoperekera, dzuwa limaphika nthaka yotentha, ndipo mpweya unali wodzaza ndi kutentha - koma chomwe chinali chotentha kuposa momwe kutentha kunali anthu ochimwa omangira nthawi yomanga. Chomera chosakanizira 1500 chated chimatsirizidwa pa nthawi yotentha kwambiri ndikuyamba ulendo wopita kudziko lina monga momwe anakonzedwera.

Zofunikira zomanga za asphalt zimayenda motere. Mafuta a kulowamo amagwiritsa ntchito asphalt pc-2, ndipo mlingo wake umatha kutsimikizika ndi kupopera kutsutsidwa molingana ndi muyezo wa 1.5 malita pa mitambo, ndipo kuwunika kwamiyala sikuyenera kukhala kochepera 5mm. Pambuyo kupopera mafuta olowa m'malo mwake, pomwe mapiri a emu-1 a phula amafunika kupatsa, kukula kwa malita a 2,5-1ct, ndipo makulidwe sayenera kukhala ochepera 0,6. Musanatasaume nephalrete, mafuta a tack ayenera kuthiridwa m'magawo apamwamba ndi otsika a chidindo chotsika, komanso m'mbali mwa ma curbs, zitsime zamvula ndi zina. Mafuta a Tack amagwiritsa ntchito emulsimed asphalt pc-3, ndipo mlingo wake ndi malita 0,5 pa mita imodzi.

Kukula kwa chisindikizo kosalala nthawi zambiri kumakhala pakati pa 1-3 masentimita, ndipo kusankhidwa kwa makulidwe kumadalira zinthu monga momwe zinthu zilili ndi kusuntha. Chisindikizo Chosachedwa chimagwiritsidwa ntchito pokonza msewu komanso moyo wabwino. Chisindikizo ichi chimakhala chopangidwa makamaka cha asphalt, simenti, filler, madzi ndi zowonjezera, zomwe zimasakanikirana ndikulimbikitsidwa. Chisindikizo chosalala chimakhala ndi gawo lofunikira pakukonza pamsewu. Pansipa tidzakhala tikuwunika mokwanira kuchokera pamasamba osankha makulidwe, ukadaulo womanga ndi kugwiritsa ntchito.

Mukamapanga chisindikizo chazithunzi chotentha, chisamaliro chapadera chiyenera kulipidwa kwa zida, ukadaulo womanga ndi zochitika zachilengedwe kuti mutsimikizire kuti zomangamanga ndi kukhazikika. Izi ndi zofunika kuziganizira: / ...
1. Kusankha kwa Zinthu zakuthupi ndi kukonza

Asphalt emulsifer mtundu wa emulsiment komanso ulusi wa polphar.s Zofunikira: ophatikizika ayenera kukhala oyera komanso owuma. Pewani kugwiritsa ntchito zinthu zopatsa chidwi kwambiri (monga basalttttt) pamatenthedwe kwambiri kuti mupewe msanga chinyezi ndikupangitsa kusakaniza kukhala wopanda phokoso.

Pambuyo pa kufalitsa kwa phula la phula lakhala likugwiritsidwa ntchito kwakanthawi, madontho ambiri azipangidwa mozungulira zida. Ngati sichinatsukidwe kwa nthawi yayitali, chotupa chofewa chidzapangidwa, chomwe chimavuta kuyeretsa. Ngakhale njira zotsukira zonsezi zimadziwika, tiyenera kulabadira nkhani zina za phula za phula za phula pokonza zomangazo.
