Black marara: mukugadzira zvigadzirwa

Black mavhu hakusi chaivo pakugadzira zvinhu, ikabereka kubva pamatombo zvinoenderana ruvara nokupwanywa kwaizotevera kugadzira nguva dzose. Dzimwe nguva munhu particulate zvinhu izvo zvinenge zvakazara rinokosha bhitumini sezvamunoita kana ugare. kugadzira Izvi zvakakodzera kuwana chigadzirwa pamwe yepamusoro abrasion nemishonga uye adhesion (adhesion unhu nevamwe kuvaka nziyo).

Types uye mafomu

Maererano GOST dema marara Classified maererano nokukura chakapatsanurwa:

1. Kubva 5 kusvika 20 mm - kusefa mavhu (the), iro rinomiririra zvikuru wakaisvonaka-grained marongerwo.
2. Kubva 20 kusvika 40 mm - svikiro-grained mavhu. The anowanzodanwa kushandiswa kuvaka.
3. Kubva 40 kusvika 70 mm - vakasindimara zvinhu, izvo panguva installation ichinge raiwanzoitwa rasklintsovka (ibwe redistribution kubvisa voids).

Black yakapwanyika ibwe chaicho giravhiti ndiro 2,9 t / mamita ^3, saka ^kuti zvifambiswe chete rinorema michina.

Kakawanda izvi zvinhu zvinoshandiswa paakapa pavements, mumaguta alleys uye dzinoungana. Uyewo nokuti akaita mugwagwa Asphalt kanivhasi. Paivakwa dzimba ane zimba kana yepasi mbishi zambara mvura.

Dzimwe nguva zvinhu ichi kujairika akashandiswa zvemaoresa ose Suburban nzvimbo.

Bulk arambe achirema pamusoro matema marara ndiyo 2900 makirogiramu.

Zvakanakira nekuipira

Pakati zvakanakira iyi ndiko kupa:

1. Neb Cracking. Ndokusaka mureza Asphalt vari kuramba kutsiva dema marara.
2. Inosimudzira fura nemishonga ine coatings yaakaita ichi zvinhu.
3. Good kuramba zvishoma nezvishoma mumatope.
4. Long pasherufu upenyu.
5. Easy compressibility.
6. Tinogona kuisira zvinhu chando.

Black marara pokuperevedza kazhinji anokudzwa:

1. High permeability zvinhu.
2. Yakarebesa nguva paumbwe yakarongwa matombo (kusvika 1 mwedzi). Kana mashoko acho kuti akaiswa kutonhora pazasi razero mukupera kwematsutso, nechepasi achaita dhayira zvinodiwa simba gore rimwe chete.

Uyewo, kana kugadzwa namabwe itsva ichava zvisingabviri angatidzvinyirira simba kusvika 5 mazuva.

Makuriro Akaita kuvakwa zvinhu zvinoenderana nzira gadzira.

Production michina nechando

marara dema kwakadaro chete kushandiswa vachigadzira pavements. nzira nokutonhorera mukugadzira zvigadzirwa nenzira mbiri: zvakananga nzvimbo kana rinokosha kugadzwa pamwe unozotevera chokufambisa kunzvimbo basa.

Kugadzirira mbishi zvinhu achishandisa tara, nebhitumini emulsions ari tembiricha inobva 100 ⁰ C 200 ⁰ C. The zvichiita zvinhu anoiswa muchando. Kana ichi zvakakodzera ndiye tembiricha, izvo zvinofanira kuva pasi +5 ⁰ C.

Cold MacAdam ari pasi viscosity, zvokuti inogona kuchengetwa pachando mudzimba kwenguva refu.

Technology okuwana anofadza nzira

Panyaya iyi, mashoko ari pasi kudziyisa kurapwa kubva 80 ⁰ C kusvika 120 ⁰ C. Rinoshandiswa kuti kurongedza marara kudziya itsva mugwagwa hukawanika ane pasi zvokuimba mutoro. Shandisa mashoko anofanira kunge ari tembiricha 60 ⁰ C kusvika 100 ⁰ C.

Production michina inopisa nzira

Hot Black akadzvinyirirwa ibwe anobudiswa panguva tembiricha kubva 120 ⁰ C kusvika 180 ⁰ C. Nokuti kurapa mashoko kuripowo kuiswa tara uye bhitumini. Chishandisei chete kana tembiricha yacho mukati + 100-120 ⁰ C.

Vanounganidza noushamwari uye inopisa MacAdam zvakakodzera pakarepo namarudzi kugadzirwa. Zvinonzi saka nguva dzose kushandiswa michina Asphalt vanomhanyisa pavements.

In maindasitiri runyararo zvokushandisa zvinodhura akashandiswa zvaAtemisi dema marara.

Uyewo zviripo tichifunga kuti yakatsvuka zvinhu zvinogadzirwa nokupesvedzera dzakakwirira tembiricha ane yakaderera chaizvo kuramba kuti paumbwe chakuvhuvhu nokuora. Kuti kubvisa chinetso ichi, vari yakapwanyika dombo akawedzera boric acid, diethanolamine uye zvakakora asidhi kuturika.

How yokugadzirira?

Kubereka yakapwanyika ibwe dema oga, zvinotevera zvinofanira hwakakanyiwa:

1. Yakapwanyika (kupfuura yakakodzera reraimu), kugiredhi M600. Zviri nani kushandisa mashoko ari pakati chakapatsanurwa (20-40 mm), sezvo rine zvakanaka absorbent ehupfumi.
2. Astringent zvinoriumba. Sezvazvakanyorwa inokurudzirwa kushandisa nebhitumini Change NOK 200/300. Bhuku racho bhainda zvinofanira sezvakarayirwa 4-5% of zvachose kurema mavhu.
3. NaOH aqueous mhinduro (fuma iyi ichashandiswa sechinhu emulsion).
4. Chakaita zvokugadzirwa mafuta asidhi mu uwandu 3% pakurema nebhitumini.
5. Electric chisanganiso aine Drum peya serin'i.
6. Mudziyo nokuti mokusvinwa zvinhu inopisa.

The chisanganiso inofanira nepokuongorora kudziyisa Kufananidzira kuti achapa aida tembiricha kunorapwa muturunhuru.

The kuvhenganisa nguva chisanganiso yenhengo zvose zvakananga kunoenderana bhuku dyisa uye kukura chisanganiso.

Kushandisa dema yakapwanyika ibwe Tile vanogona nezvemakwara zvose pamusoro Suburban chikamu, kubereka pamusoro rukoko mapofu yakapoteredza mumba kana kuronga yakavimbika uye rakasimba mestodlya yokupakira motokari yake. Zvisinei, chinofanira kufunga kuti iri private pakuvaka zvinogoneka kushandisa nezvimwe, zviri nyore zvikuru uye isingadhuri kuti maoko ako pasina kushandisa kudziyisa zvinhu. Kunze kuisa nhema mavhu zvakaoma chaizvo kuita oga.
