Ko te bitumen tino pakari me te rapa nui he matū kua whakanekehia he matū matū kua whakahurihia motuhake me te kupenga rereke-toru pai. Ko tona waahi ngohengohe ka eke ki runga ake i te 85°C me tona pokey hihiri ka eke ki runga ake i te 580,000 Pa·s. He bitumen whakakē-nui-nui. Ko te pokey hihiko he 3 nga wa o te bitumen whakarerekētia, he pai te mahi pāmahana teitei. I te wa ano, ka eke tona ngongo ki runga ake i te 45cm, he pai rawa atu te kapiti pāmahana iti, te whakaora rapa nui atu i te 95%, he pai te kaha ki te whakaora deformation me te tino uaua me te aukati kapiti.
Ko te matauranga e pa ana ki te pokey teitei te elasticity teitei me te uaua nui kua whakarereketia te bitumen_2
Ko te ranunga bitumen kua whakarerekēhia te kaha teitei me te elasticity he tino pai te pumau o te pāmahana teitei, te pumau o te wai, te parenga marara, te pakari-nui me te kapiti parenga, te hanganga ture me te mauroa. Ko tenei hua he maha nga ahuatanga o te tono. Ko te matotoru o te whakakikorua ultra-aniangi ka taea te whakaheke ki te 1.2 cm, ka taea te roa o te ratonga ki te 8 tau. Ka taea te whakamahi hei whakakikorua mo te whakakikorua i nga papa raima i runga i nga momo reanga o nga huarahi nui me nga rori taone, nga raima raima, me nga piriti. kanohi me te kauhanga kanohi. I tua atu, ka taea hoki te whakamahi i te bitumen whakarereke teitei me te elasticity i roto i te hautai taone permeable pavements, paparanga absorption ahotea, paparanga here parewai, etc.
