Marka qalabka dhirta isku dhafka ah ee asphalt uu shaqeeyo, boodh badan ayaa inta badan ka soo baxaya goobta dhismaha, sidaas darteed waxaa lagama maarmaan ah in lagu qalabeeyo qalab u dhigma boodhka. Guud ahaan, boorsada boorsada qaada ayaa la isticmaalaa, bacda shaandheynta boodhkana waa shay shaandhayn wax ku ool ah oo leh hawo-qaad wanaagsan, hufnaan sare oo ka saarista boodhka, iyo aashitada, alkali iyo caabbinta kulaylka qaarkood.
Muddo dheer ka dib isticmaalka, si loo sii wado shaqada warshadda isku dhafka asphalt, bacda shaandhada boodhka waxay u baahan tahay in la nadiifiyo. Maadaama bacda shaandhada boodhka ay tahay qayb aad u muhiim ah oo ka mid ah boorsada boorsada boorsada, waxay leedahay waxqabad hawo wanaagsan, hufnaanta boodhka sare ee saarista, iyo qaar ka mid ah acid, alkali iyo caabbinta kulaylka. burush dhinacyo badan leh ayaa loo isticmaalaa habka tolida si ay u kordhiso dhumucda marada oo ay ka dhigto mid jilicsan, markaa saamaynta ka saarista boodhka ayaa ah mid aad u fiican, iyo nolosheeda adeeggu guud ahaan afar ilaa lix jeer ka badan muraayadda fiber-ka, sidaas darteed nadiifinteeda shaqadu aad bay muhiim u tahay.
Haddaba, waa maxay waxa ku jira shaqada nadiifinta ee bacda shaandhada boodhka ee warshadda isku dhafka ah ee asphalt?
Ugu horreyntii, sababtoo ah xaaladaha dhabta ah ee kala duwan, ka hor inta aan la nadiifin, si loo hubiyo saameynta nadiifinta, waxaan u baahanahay inaan sameyno tijaabooyin kiimiko ah. Tillaabooyinka ugu muhiimsan waa in la soo saaro muunadda bacda, isticmaal qalab xirfadle ah si loo tijaabiyo qaybaha saliidda iyo wasakhda bacda shaandhada, dooro agabka dhaqida ku habboon iyadoo loo eegayo nuxurka qaybaha, iyo nadiifinta bacda shaandhada boodhka ee dhirta isku dhafka ah ee asphalt ugu badnaan iyada oo aan waxyeello loo geysan.
Midda labaad, wasakhda ay fududdahay in dusha sare laga saaro waxa marka hore ka saari kara gariir aad u sarreeya, si wasakhda waaweyn iyo wasakhda soo gelaysa gidaarka bacda shaandhada marka hore meesha laga saaro, wax saamayn ahna kuma yeelanayso isku-xidhka fiber-ka. , ilaalinta waxqabadka boorsada shaandhada boodhka ee saldhiga isku dhafka asphalt iyo fudaydka fudud ee wasakhda. Ka dib, dooro walxaha kiimikaad ee ku habboon si aad u qoyso bacda shaandhada, ka saar wasakhda saliidda iyo wasakhda ku jirta farqiga u dhexeeya bacda shaandhada, oo kordhiso xawliga hawada ee bacda shaandhada ilaa xadka ugu badan.
Kadibna, shaqada nadiifinta ayaa loo baahan yahay. Marka loo eego xaalada kor ku xusan, marka hore dooro alaabta dhaqida ku haboon, isticmaal biyo kulayl yar si aad u nadiifiso, u ilaali socodka biyaha lebbiska, xoojinta dhexdhexaadka ah, oo ha u geysan dhaawac bacda shaandhaynta boodhka ee warshadda isku dhafka ah ee asphalt. Kadibna, amarku waa qalajin, hagaajin iyo tijaabin si loo hubiyo in tayada nadiifinta ay buuxiso shuruudaha.
