Ibice bibiri bigize umuhanda uranga irangi nigisubizo cyiza cyane cyo gukora ibimenyetso biramba, birebire kumihanda no mumihanda. Igizwe n'ibice bibiri bitandukanye: shingiro (mubisanzwe resin) hamwe no gukomera (umukozi ukiza). Iyo bivanze hamwe, ibyo bice bigira imiti ihindura irangi ryamazi muri firime ikomeye, iramba ifata cyane hejuru yumuhanda.
Siyanse iri inyuma yiri bara iri muburyo bwo gukiza imiti. Shingiro no gukomera byateguwe kubyitwaramo iyo bihujwe, bitangiza inzira ya polymerisation. Ibi birema umuyoboro uhuza molekile, bikavamo igipfundikizo gikomeye, kirwanya abrasion. Uku guhuza bituma irangi riramba cyane kuruta ibisanzwe bisanzwe bigize ibice, bigahumeka ikirere gusa cyangwa bigashingira ku bushyuhe bwo gushiraho.
Inyungu zingenzi ziyi reaction ni ukongera imbaraga mukurwanya ibidukikije nkimvura, urumuri rwa UV, nihindagurika ryubushyuhe. Irangi rikomeye rirwanya kwambara kubinyabiziga, byemeza ko ibimenyetso bikomeza kugaragara kandi bitameze neza nubwo haba harimodoka nyinshi. Byongeye kandi, amarangi yibice bibiri akunze kuba arimo amasaro yerekana neza atera imbere nijoro cyangwa mubihe bito bito, bikamura umutekano muke.
Ikindi kintu cyingenzi kiranga ibice bibiri bigize umuhanda uranga irangi ni byinshi. Irashobora gukoreshwa mubice bitandukanye, harimo asfalt, beto, ndetse nicyuma. Ibi bituma ikwirakwira muburyo butandukanye bwo gusaba, kuva mumihanda kugeza aho imodoka zihagarara hamwe nabanyamaguru.
Mu gusoza, siyanse iri inyuma yibice bibiri byerekana umuhanda irangi yashinze imizi muburyo bwo gukiza imiti, itanga igihe kirekire, irwanya ikirere, kandi igaragara cyane. Ibiranga bituma ihitamo neza kumihanda ifite ubwinshi bwimodoka kandi ikenera ibimenyetso birebire, byizewe.
