Enwere ọtụtụ ụdị asphalt n'ahịa, yabụ kedu ka anyị maara maka ụkpụrụ nrụpụta nke asphalt roba? Ka anyị leba anya ọnụ.
Rubber asphalt bụ ihe mgbakwunye asphalt gbanwere site na mbụ nhazi taya mbụ n'efu ka ọ bụrụ ntụ ntụ rọba, wee jikọta ya dị ka ụfọdụ oke na ezigbo grading, na-agbakwunye ọtụtụ ụdị polymer modifiers, yana agbaze na ọzịza na asphalt matrix. n'okpuru ọnọdụ okpomọkụ dị elu (karịa 180 Celsius) na ngwakọta zuru ezu. A na-aghọtakarị ya dị ka asphalt na roba agbakwunyere. Rubber asphalt nwere nkwụsi ike dị elu nke okpomọkụ, mgbanwe okpomọkụ dị ala, mgbochi ịka nká, ike ọgwụgwụ, na nkwụsị mmiri. Ọ bụ ihe pavement dị mma na gburugburu ebe obibi ma na-ejikarị ya na oyi akwa mgbakasị ahụ na oyi akwa nke ihe owuwu okporo ụzọ.

Enwere echiche atọ a ma ama maka "asphalt rubber": "usoro akọrọ" rubber asphalt, "usoro mmiri mmiri" rubber asphalt, na "usoro ngwakọta nke asphalt" asphalt roba.
(1) "Ụzọ nkụ" rubber asphalt bụ ka a na-ebu ụzọ gwakọta ntụ ntụ rọba na mkpokọta, wee tinyezie asphalt maka ịgwakọta. Usoro a

Kedu uru nke asphalt rọba ma e jiri ya tụnyere asphalt nkịtị?
1. Mgbochi na-atụgharị uche
Na roba asphalt mgbakasị ahụ oyi akwa, a nnukwu ego nke roba asphalt na-ike bonded na gravel nke otu urughuru size na-etolite a mgbawa Ọdịdị oyi akwa ihe dị ka 1cm n'obosara. Ọkpụkpụ dị iche iche dị na oyi akwa mmiri kwụsiri ike ma ọ bụ pavement ciment ochie ga-esiri ya ike ịbanye n'ime oyi akwa a, nke nwere ike igbochi ntụgharị nke mgbawa nke ọma.
2. Mgbochi mmiri na-emebi
Ọnụ ọgụgụ asphalt roba buru ibu (2.3kg / m2), a ga-emepụta ihe nkiri asphalt nke ihe dịka 3mm ọkpụrụkpụ n'elu okporo ụzọ, nke nwere ike igbochi mmiri ozuzo kpamkpam ịbanye n'ime ala ma chebe ebe ahụ. Nke abuo, mgbe a na-emepe ngwakọta nke asphalt na ya, asphalt roba nke dị n'elu akwa mkpuchi asphalt nke rọba ga-agbaze nke ugboro abụọ, na mgbe agbakọchara ụzọ ahụ, ọ ga-ejupụta oghere dị na ala nke ngwakọta elu. , si otú ahụ na-ewepụ ohere nke nchekwa mmiri n'etiti akwa akwa na igbochi mmebi mmiri.
3. Mgbakwunye mmetụta
Rubber asphalt nwere nnukwu viscosity siri ike. Enwere ike ịgbanye ya ma jikọta ya na oyi akwa mmiri kwụsiri ike ma ọ bụ pavment ciment ochie nke ọma, si otú a na-arụ ọrụ njikọ na elu okporo ụzọ.
