Asphaltic Density: kuyerera mwero uye Kuronga zvinhu

Nokuti nyika kuvandudzika uye kuvaka migwagwa nhasi inowanzoshandiswa Asphalt kongiri, izvo zvinoita kuti vawane Zvinokosha zvakaisvonaka uye yepamusoro unhani. Izvi zvinhu musanganiswa nebhitumini dzinongoitika zvokuvakisa.

Natural zvinhu zvinopa simba, nepo bhitumini inodiwa tichisunga vapinde unitary marongerwo. Asphalt ari pamusoro chete michina munyika dzakasiyana, asi unhani unhu kunobva zvakamisa hurongwa kuti akawedzera kana kwete yebhasera musanganiswa dzimwe nguva anoona uye kuisira nzira.

The arambe achirema mashoko

The arambe achirema of Asphalt kongiri - mumwe chikuru zvechadenga ichi zvinhu. Asphaltic kongiri, saka anonziwo, ari muchimiro kuvakwa chakagadzirwa conglomerate, iyo yakaumbwa somugumisiro kuwana anodiwa arambe achirema pakati musanganiswa yakatakura pamasikiro. The sezvamunoita yakagadzirwa ne nzira vachisanganisa chaiyo dzakabatana pasi pokudzora tembiricha. Izvi anoshandisa mafuta mugwagwa nebhitumini uye chicherwa yezvikamu zviduku zveropa zvakasiyana zvokuvakisa, vari musanangurwa zvikuru yakajeka. Dzimwe nguva akawedzera Polymers, rabha, surfactants, sarufa nezvakadaro.

Asphalt kongiri arambe achirema kunobva mhando. Somuenzaniso, rizere musanganiswa ane arambe achirema iri kuwanda 2340 makirogiramu / m ^3, nezvemitambo porous musanganiswa, ayo arambe achirema ndiyo yaita kudzika - 2300 makirogiramu / m ^3. The yakanaka-grained Asphalt kongiri musanganiswa mhando A, B uye C vane zvinotevera densities: 2385, 2370 uye 2343 makirogiramu / m ^3, ukuwo. It kunoitika muna Asphalt jecha marudzi "musanganiswa mhando D" pane izvi, kuti parameter kufarira akaenzana 2280 makirogiramu / m ^3.

arambe achirema

Kuziva arambe achirema pamusoro Asphalt kongiri riri kuitwa Murabhoritari miedzo yacho ivhu kuti zvakabudiswa coatings. parameter ichi rinowanikwa nevanhu nhamba avhareji arambe achirema kwemashoko, iyo wakabviswa unhani, kuti reshape avhareji arambe achirema dzokuenzanisira.

Nokuti mumwe mhando musanganiswa rinoshandiswa munhu compaction reshiyo. Somuenzaniso, nokuti wemisanganiswa ose A uye B reshiyo ndiyo 0.99, mix B, D uye E, uye nechezasi chinoumba akaturikidzana coefficient ndiyo 0,98. Kana vamwe zvokubikisa zviri chakagadzirwa ibwe wamabwe, reshiyo ave akaenzana 0,97.

kudyiwa Asphalt kongiri

Hazvina chete arambe achirema yakaisvonaka-grained Asphalt kongiri uye ayo dzimwe mhando, asiwo rakawanda. Kazhinji, parameter ichi akatsunga pamusoro 100 mamita ^2, asi pakukora dzingasiyana. In porous uye gobvu muvhenganiswa pamwe marongera Ukobvu 55 mm kudyiwa pa 100 mamita ² vachava 12,87 uye 12,65 m, ukuwo. With kuwedzera rukoko 80 mm gobvu uye porous kuerera muvhenganiswa achava akaenzana 18.7 uye 18.4 m, ukuwo.

The yakanaka-grained Asphalt kongiri muvhenganiswa mhando A ane yakaderera aibuda mwero kana zvakaturikidzaniswa ipfupi kusvika 35 mm. Saka 100 mamita ² siya 8.35 m. A nyaya jecha Asphalt kunovhengana mhando D, ipapo zvakaturikidzaniswa Ukobvu 45 mm manwiro mari kuti 10.26 M chete 100 mamita ^2.

arambe achirema mita

Asphalt kongiri arambe achirema mita inogona kutengwa dzakagadzirirwa muzvitoro. It anosarudza kuti arambe achirema pamusoro unhani uye nhandare yacho mugwagwa. Sezvo rwendo mudziyo anoita operative kudzora arambe achirema, panguva iyo munhu anogona kuziva mwero inhomogeneity uye chisimbiso nezvigadziko uye mugwagwa coatings.

Mudziyo anogona kuziva unconsolidated mapazi uye kudzora dzinonetsa nharaunda, pano zvinofanira kunzi micheto uye mapfundo. With payo, avhareji arambe achirema pamusoro asphaltic kongiri, inova 2.35 g / ^cm3 kunogona tsunga. Equipment Anoongorora sei zvakanaka unhani, kunyange pamberi pokushandisa pamusoro rukoko. Mudziyo anogona kuyera tembiricha iri Asphalt, kuti asarudze compression reshiyo, kuti aite tembiricha-ndanyarara hangu arambe achirema kuverenga.

The Kuronga Asphalt kongiri uye ehurumende mitemo

The arambe achirema of Asphalt kongiri, GOST iyo anosarudza kunaka zvokunyama uye runotaurwa anotevera nenhamba: 9128-2009 - radudzwa pamusoro. Zvisinei, nyanzvi vanofanira kuziva zvakawanda pamusoro nziyo. The bemhapemha ane kana mavhu chips pakati zvinhu zviri comminuted uye muvhuruvhuru. Sezvo chikamu mujecha ikoko.

Sezvataurwa pamusoro apa, mashoko bhitumini kuita sechinhu anotsvedzerera anobuda pamiti nemakwenzi chigadzirwa inoti zvakamisa hurongwa pamwe chete. Zvisinei, mashoko aya anofanira kuiswa kupopotedzana mamiriro. It rinotsanangura uye Asphalt kongiri tichigadzira rwokugadzira. Asi nhasi pane zvigadzirwa kuti anobvumira kuti vawane bhitumini aine viscosity anosvika +5 ° C. Mafuta chinogadzirwa ne nzira ano, iyo anobvumira kuwana Bhitumini pasina frosting kuti achitsoropodza yakaderera tembiricha kwakadzikira. Yemanyorero mutengo uyu -30 ° C.

The arambe achirema of Asphalt kongiri (t / m3) ndiyo 2.35. Asi kukosha ichi - kwete chete chinhu kuti kuziva nyanzvi. Somuenzaniso, zvicherwa tigutsikane rakakamurwa zvitatu tsika:

• Group A: 50 kusvika 60% (yakapwanyika ibwe kana mavhu);
• Group B: kubva 40 kusvika 50% (zvicherwa);
• Group B: kubva 30 kusvika 40% (yakapwanyika ibwe kana mavhu).

muturunhuru rweNhengo yaidzorwa nokurondedzerwa. Maererano izvi zvinhu kugadzirwa muchishandisa marara, the ringaita dzinosiyana 10 kusvika 20 mm. sezvamunoita kwakadaro rinoshandiswa kuumba pamusoro paiva web. The zvemichina iri kwakajairika uye zvikuru kushandiswa nhasi, asi musanganiswa inogona kuwedzerwa kuna Polymers.

Kuchinja Asphalt kongiri pasi pokudzora yazvino

The arambe achirema of Asphalt kongiri maererano National mitemo, vanofanira kuramba chete, asi kunaka acho nguva dzose kuvandudzika. Izvi imhaka kuramba mitoro mumugwagwa pamusoro, zvoita kuti kutsvaka yemhando zvokuvakisa kuvandudza. Somugumisiro, izvozvo vakakwanisa kusika munhu kukandira Asphalt kongiri, rakanga raitwa inorondedzerwa kumusoro.

Rinoshandiswa kwete chete nokuda kweDzimba asiwo Nokuraramisa migwagwa. Michina iyi nokudzorwa zvinodiwa nehurumende uye P 54401-2011 kunosanganisira vanoungana muvhenganiswa pasina compaction. Saka tembiricha conglomerate rinotanga pa 190 ° C, kuwedzera kwevari plasticity inowedzera. Zvinoumba dzinoratidzwa kwakadaro zvinhu nokuda polymer yokuvirisa.

The kukandira Asphalt sezvamunoita ine zvinopfuura Asphalt, asi bhuku zvicherwa kunoderedza. Mukati mavhu chakapatsanurwa kusvika 5 mm kunobva ½ chikamu kusvika zvachose kurema 0%. Musanganiswa vakawana hakusi grainy, saka zvinoitika viscous uye hachisi chokutsanangura kusimbisa.

mamwe zvinhu

An Asphalt bhainda anovandudza zvinooneka ehupfumi, saka unhani zvinhu anomupa simba mukuru, mukurumari, kuvimbika uye refu hwose pasina cracking walnut. Asphalt kongiri arambe achirema inoramba chete, asi zvakakosha kucherechedza mabikirwo uyewo chinoumba reshiyo. Ndiyo munjodzi kwemashoko chinosiyanisa kukandira Asphalt. Kana panguva kugadzirwa danho kunoitika yakatsauka kubva nemirau, simba unhu vanotambura.

mhedziso

Asphalt kongiri anobatsirwei pakuti rinogona yakashongedzwa. Izvi akawedzera zvikuru kukura kwebasa kushandiswa kwayo, kubatsira zvinhu kunogona kuita kubva yakanaka njanji, menzira uye alleys nekuti pamwe. On the mugwagwa uchishandisa zvigadzirwa izvi akazviratidza mavara Asphalt, izvo zvinoratidza chime kuyambuka, zvichiratidza uye kupatsanura rinoparadza.

Nzira kunosanganisira kuwedzera murwiyo mavara 5-mm akadzvinyirirwa ibwe, jecha uye pigments zvakagadzirwa girenayiti, clinker, namatema uye reraimu. For asphaltic inopenya rinoreva kushandiswa yakajekesa chakaita zvokugadzirwa bitumens. The zvemichina kunowedzera mari nhau, saka kashoma kushandiswa.

Asi nhasi aifanira kutsvaka imwe nzira kuparadzira. Anoti vachidzipukuta yechitema machipisi, apo neDare achiwedzera pakuburitswa akaramba. In danho nokuisa migwagwa uye kuenda Kunze rokumusoro unhani rukoko.
