Kukho iintlobo ezininzi ze-asphalt kwimarike, ngoko ke siyazi kangakanani malunga nomgaqo wokuvelisa i-asphalt yerubha? Makhe sijonge kunye.
I-asphalt yerabha sisibophelelo se-asphalt esilungisiweyo esakhiwe ngokuqala ukusetyenzwa kwetayara lenkunkuma lokuqala libe ngumgubo werabha, emva koko lidityaniswe ngokomlinganiselo othile orhabaxa kunye nomgangatho olungileyo, ukongeza iintlobo ngeentlobo zezilungisi zepolymer eziphezulu, kunye nokunyibilika ngokupheleleyo kunye nokudumba nge-asphalt ye-matrix. phantsi kweemeko eziphezulu zokushisa (ngaphezu kwe-180 ° C) kunye nokuxuba okupheleleyo. Ngokuqhelekileyo iqondwa njenge-asphalt kunye nerabha eyongeziweyo. I-asphalt yerabha inozinzo oluphezulu lobushushu, ukuguquguquka kobushushu obuphantsi, ukuchasana nokuguga, ukulwa nokudinwa, kunye nokumelana nomonakalo wamanzi. Yimathiriyeli yendlela ehambelana nokusingqongileyo kwaye isetyenziswa ikakhulu kumaleko wokufunxa uxinzelelo kunye nomaleko ongaphezulu wezakhiwo zendlela.

Kukho iingcamango ezintathu ezidumileyo ze "asphalt yerabha": "indlela eyomileyo" i-asphalt yerabha, "indlela emanzi" i-asphalt yerabha, kunye "nendlela yokuxuba i-asphalt depot" i-asphalt yerabha.
(1) "Indlela eyomileyo" i-asphalt yerabha kukuxuba umgubo werabha kunye ne-aggregate kuqala, kwaye wongeze i-asphalt yokuxuba. Le ndlela
kukujonga umgubo werabha njengenxalenye yeaggregate, kodwa ngokubanzi isixa somgubo werabha asinakuba phezulu kakhulu. Le ndlela ayifane isetyenziswe.
2 Ngoku yeyona ndlela isetyenziswa kakhulu ekuveliseni i-asphalt yerabha.
(3) "Indlela yokuxuba idepho ye-asphalt" ibhekiselele ekuxutyweni komgubo werabha wenkunkuma kunye ne-asphalt eshushu kwindawo yokucokisa okanye yokugcina i-asphalt, kwaye emva koko isiwe kwisikhululo sokuxuba i-asphalt ikhonkrithi okanye indawo yokwakha. "Indlela yokuxuba idepho ye-asphalt" eneneni inokuthathwa njengoluhlobo "lwendlela emanzi" yemveliso, kodwa ukusetyenziswa kwayo komgubo werabha okulahlwayo ngokuqhelekileyo akudluli kwi-10%, ukusetyenziswa komgubo werabha kuphantsi, kwaye i-viscosity ingaphantsi kunaleyo ye-asphalt yerabha. ("indlela emanzi" imveliso). Umxube odibeneyo awukwazi ukufikelela kwintsebenzo efanayo nomxube we-asphalt yerubha.
Ziziphi iingenelo ze-asphalt yerabha xa kuthelekiswa ne-asphalt eqhelekileyo?
1. Iintanda ezichasayo
Kumaleko wokufunxa ngoxinzelelo lwe-asphalt yerabha, isixa esikhulu se-asphalt yerabha idityaniswe ngokuqinileyo negrabile yobungakanani besuntswana elinye ukwenza umaleko wesakhiwo somfanekiso wokuqhekeka malunga ne-1cm ubukhulu. Ukuqhekeka okuhlukahlukeneyo kwinqanaba elizinzile lamanzi okanye kwi-pavement endala yesamente kuya kuba nzima ukungena kulo maleko, onokuthi uthintele ngokufanelekileyo ukubonakaliswa kweentanda.
2. Umonakalo ochasene namanzi
Ubungakanani be-asphalt ye-rubber bukhulu (2.3kg / m2), kwaye ifilimu ye-asphalt malunga ne-3mm ubukhulu iya kwenziwa kwindlela ehamba phambili, enokuthi ithintele ngokupheleleyo amanzi emvula ukuba angene phantsi kwaye akhusele i-roadbed. Okwesibini, xa ugalela umxube we-asphalt kuyo, i-asphalt yerabha engaphezulu kwe-asphalt yoxinzelelo lwe-absorption layer iya kunyibilika okwesihlandlo sesibini, kwaye emva kokuba umphezulu wendlela udityanisiwe, uya kugcwalisa ngokupheleleyo isithuba esisezantsi kumxube ongaphezulu. , ngaloo ndlela kucinywa ukubakho kokugcinwa kwamanzi phakathi kweengqimba kunye nokuthintela umonakalo wamanzi.
3. Isiphumo sokudibanisa
I-asphalt yerabha ine-viscosity eyomeleleyo. Iyakwazi ukubhengezwa kwaye idityaniswe kuluhlu oluzinzile lwamanzi okanye kwindlela endala yesamente ngokuqinileyo, ngaloo ndlela idlala indima yokudibanisa kunye nomphezulu wendlela.
