Kekọrịta:
1. Transparent oyi akwa ewu technology
1. Ọrụ na ọnọdụ ọdabara
(1) Ọrụ nke permeable oyi akwa: Iji mee ka asphalt elu oyi akwa na isi oyi akwa jikọtara nke ọma, emulsified asphalt, coal pitch ma ọ bụ mmiri mmiri asphalt wụsara na isi oyi akwa na-etolite a mkpa oyi akwa na penetrates n'ime elu. isi oyi akwa.
(2) Ụdị isi ala niile nke pavement asphalt ga-eji mmanụ na-abanye n'ime ya fesa. Mgbe ị na-edobe oyi akwa mkpuchi ala n'elu oyi akwa, a gaghị ahapụ mmanụ oyi akwa nke nwere ike ime.
2.General chọrọ
(1) Họrọ asphalt mmiri mmiri, emulsified asphalt, na coal asphalt nwere ezigbo ikike dị ka mmanụ na-abanye n'ime ya, wee kwado ya site na mkpọpu ma ọ bụ ngwuputa mgbe ịgbasachara ya.
(2) Enwere ike imezi viscosity nke asphalt mmanụ na-emebi emebi ka ọ bụrụ viscosity kwesịrị ekwesị site n'ịgbanwe ọnụọgụ nke diluent ma ọ bụ ntinye nke asphalt emulsified.
(3) A ga-efesa mmanụ penetrating nke a na-eji maka oyi akwa nke ọkara siri ike ozugbo a kpụchara akwa akwa ahụ ma guzobe ya, mgbe elu ya na-akọrọ ma ọ kabeghị ike.
(4) Oge ịgbanye mmanụ na-abanye n'ime: Ekwesịrị ịfesa ya ụbọchị 1 ruo 2 tupu ịkwanye oyi akwa asphalt.
(5) The ọgwụgwọ oge mgbe penetration oyi akwa mmanụ na-agbasa kpebisiri ike site nnwale iji hụ na diluent na mmiri mmiri asphalt bụ kpamkpam volatilized, na emulsified asphalt penetrates na mmiri evaporates, na asphalt elu oyi akwa na-tọrọ ozugbo o kwere omume. .

3. Akpachara anya
(1) Mmanụ na-abanye ekwesịghị ịfesa mgbe agbasachara ya. Ọ ga-abanye n'ime oyi akwa dị n'okpuru ebe dị omimi ma ghara ịmepụta ihe nkiri mmanụ n'elu.
(2) Mgbe okpomọkụ dị ala karịa 10 ℃ ma ọ bụ ikuku na-eku ma ọ bụ na ọ ga-ezo, agbala mmanụ na-abanye.
(3) Machibido iwu nke ndị mmadụ na ụgbọ ala mgbe ha fesachara mmanụ n'ime.
(4) Wepu ngafe asphalt.
(5) Ntinye n'uju, awa 24.
(6) Mgbe enweghị ike ịmebe oyi akwa n'elu n'oge, gbasaa oke nkume ma ọ bụ ájá siri ike kwesịrị ekwesị.
2. Nkà na ụzụ nrụpụta nke oyi akwa nrapado
(1) Ọrụ na ọnọdụ ọdabara
1. Ọrụ nke nrapado oyi akwa: ijikọ kpamkpam n'elu na nke ala asphalt structural layers ma ọ bụ asphalt structural oyi akwa na Ọdịdị (ma ọ bụ ciment concrete pavement) n'ime a dum.
2. Ọ bụrụ na ezutere ọnọdụ ndị a, a ga-efesa asphalt nrapado:
(1) N'etiti akwa asphalt nke okpukpu abụọ ma ọ bụ okpukpu atọ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ.
(2) A na-edokwasị akwa asphalt na pavement simenti, asphalt stabilized gravel base ma ọ bụ oyi akwa asphalt ochie.
(3) N'akụkụ ebe mgbochi mmiri, mmiri mmiri ozuzo, olulu mmiri nyocha na ihe ndị ọzọ na-ejikọta na ngwakọta asphalt ọhụrụ ahụ.
(2) Ihe achọrọ n'ozuzu
1. Nka na ụzụ chọrọ maka nnyapade oyi akwa asphalt. Ugbu a, mgbape ngwa ngwa ma ọ bụ ọkara-crack emulsified asphalt na emulsified asphalt na-ejikarị eme ihe dị ka ihe nnyapade oyi akwa. Ngwa ngwa na ọkara ntọala mmiri mmiri asphalt nwekwara ike iji.
2. The onunu ogwu na iche iche nhọrọ nke nnyapade oyi akwa asphalt.
(3) Ihe ndị a ga-arịba ama
(1) Ebe a na-efesa ga-adị ọcha ma kpọọ nkụ.
(2) Amachibidoro ịgbasa mgbe okpomọkụ dị n'okpuru 10 ℃ ma ọ bụ elu okporo ụzọ dị mmiri.
(3) Jiri gwongworo na-agbasa asphalt na-efesa.
(4) Mgbe ịgbasa asphalt ahụ na-egbuke egbuke, jide n'aka na ị ga-echere ka emulsified asphalt gbajie na mmiri na-ekpochapụ tupu ịtọba akwa oyi akwa nke asphalt.
