Ko tete tipu bitumen whakarereke polymerhe painga o te kounga pono, te mahi pumau, te ine tika me te mahi watea, a he taputapu hou mo te hanga huarahi.

I enei wa, ka whakamahia te hangarau polymer i whakarerekehia e te kairangahau me te kaihanga i roto i te whakaehunga parapara hei whakapai ake i te mahi o te whakaehunga parapara. He maha nga momo waerau ka taea te whakamahi ki te whakarite polymer  whakarereke uku whakaehunga penei i te styrene  butadiene styrene (SBS) block copolymer, ethylene vinyl acetate (EVA), polyvinyl acetate (PVA), styrene butadiene rubber (SBR), latex, epoxy resin me te rapa maori. taherapa. Ka taea te whakauru i te polymer ki roto i te whakaehunga uku i roto i nga huarahi e toru: 1) tikanga whakahanumi i mua, 2) tikanga whakahanumi tukutahi me te 3) tikanga whakakotahi i muri. He awe nui te tikanga  whakaranu ki te tohatoha kupenga waerau, ka pa ki te mahi o nga whakaehunga whakaehunga polymer kua whakarereketia. Na te kore o te kawa i whakaaehia ka taea te whakamahi i nga momo tikanga ma nga taiwhanga whakamatautau kia whiwhi toenga whakangao uku. Ko tenei pepa he tirohanga whanui mo nga rangahau i whakahaeretia mo nga whakaehunga waikura kua whakarereketia ma te whakamahi i nga momo momo waerau me te mahinga o tana whakamahinga.

Sinoroaderte tipu bitumen whakarereke polymerKa taea te whakamahi mo te whakarereke i te uku, kei roto ko te mira colloid, te punaha whangai whakarereke, te tank rauemi kua oti, te taika whakaranu whakawera whakawera, te punaha whakahaere rorohiko me te taputapu pauna hiko. Ko te tukanga whakaputa katoa e whakahaerehia ana e te kaupapa rorohiko aunoa.
