Ayini ama-Slurry Seals?

Amanzi ashelelayo ayindlela yamanzi, i-asphalt emulsion, i-aggregate, nezinye izengezo endaweni ekhona yephansi. I-slurry seal ifana ne-fog seal ngaphandle kwe-slurry seal enezinto ezihlanganayo njengengxenye yomxube. I-Polymer iyisengezo esivamile esithuthukisa izakhiwo ze-asphalt emulsion. Le nhlanganisela ehlangene ye-emulsion nama-aggregates yilokho okubizwa ngokuthi yi-slurry ukuze kuvikeleke ukwakheka komhlaba ongaphansi komhlaba nokunikeza umgwaqo omusha womgwaqo.

Yini Izinhlamvu Zenkungu?

Ukubekwa kwenkungu kubhekiswa kusetshenziswa kwe-asphalt emulsion ekhethekile eyenziwe endaweni ekhona yomgwaqo wasephalt. I-fog seal emulsion inengxube yama-oyili wamanzi, engafafazwa kalula emendweni osele ukhona, owaziwa nangokuthi "fogging."

Yini ama-Chip Seals?

Ukusetshenziswa kweshidi le-chip kufaka phakathi i-asphalt emulsion equkethe ama-globules e-asphalt, amanzi, i-ejenti emulsifying noma i-survivant, i-polymer, futhi imvamisa isengezo sokuvuselela amandla. Izimpawu ze-CHip zisetshenziselwa inqubo yezinyathelo ezimbili ezibandakanya kuqala ukusatshalaliswa kwe-asphalt emulsion bese kuthi ngemuva kwalokho kube yingqimba yedwala elincane elichotshoziwe endaweni ekhona yomgwaqo wasephalt. Idwala elincane elichobozekile libizwa nangokuthi “izicubu”, enikeza i-chip yokubeka uphawu igama layo.

Yini amaScrub Seals?

Ukwelashwa kwe-scrub seal kufana kakhulu nokufakwa uphawu kwe-chip, lapho kusetshenziswa i-asphalt emulsion ne-gravel echobozekile ukuvuselela umgwaqo olimele we-asphalt. Umehluko kuphela indlela yokufaka isicelo: Ukuze kusetshenziswe uphawu lwescrub, i-asphalt emulsion isetshenziswa yilokho okubizwa ngokuthi yimishanguzo, okuqinisekisa ukuthi i-asphalt emulsion ingena ekuguguleni kwendlela.

Yini ama-Seal Cape?

Ukubekwa uphawu kwensimbi yaseCape kusho ukusetshenziswa kwe-chip noma iscrub seal ngesicelo esilandelako se-slurry seal noma i-microsurfacing ngemuva kwesikhathi. Ngenkathi i-chip noma i-scrub seals seal futhi ibopha imifantu kusendlalelo ekhona ekhona, uphawu olushelelayo noma isibonakhulu esincane sithuthukisa ukugcinwa kwe-chip nobushelelezi bomgwaqo wendlela. ICape ibopha uphawu olusetshenziswa kakhulu njengezikhathi zokusebenza ngezikhathi ezithile, ezisetshenziselwa ukwakheka kwe-asphalt okubonisa kuphela usizi olulinganiselayo, ukonakala okuncane noma okungekho, ububanzi obuqhekekile bokuqhekeka. Ukubopha uphawu kweCape kusetshenziswa kakhulu njengendlela yokwandisa impilo yendawo yokuhlala kuze kube yilapho kwenziwa kabusha noma kwakhiwa kabusha.

Yini i-Microsurfacing?

I-Microsurfacing ukwelashwa okuqhathaniswa ne-slurry seal. Ukuze uthole imicrosurfacing, isakhi esakhiwa emanzini, i-asphalt emulsion, i-aggregate, nezinye izithasiselo zamakhemikhali asetshenziswa ngaphezulu kwendlela egandayiwe kukakhonkolo. Izithasiselo zePolymer zisetshenziselwa ukwenza ngcono izakhiwo zezingxube ze-asphalt emulsion. Umehluko omkhulu phakathi kwe-slurry seal ne-microsurfacing yindlela yokuthi "baphuka" noma baqina kanjani. Ngenkathi ukubopha uphawu kufiphaza kudinga ukuthi amanzi avele kusuka ku-asphalt emulsion ngemuva kokusatshalaliswa kwayo, i-asphalt emulsion ekuhlanganisweni okuyi-microsurfacing iqukethe izithasiselo zamakhemikhali ezikuvumela ukuthi ziphule ngaphandle kokuncika elangeni noma ekushiseni ukuze kuphume amanzi. Lokhu kwenza i-microsurfacing indlela yokwelashwa ethandwa kakhulu yemigwaqo esetshenziswa kakhulu (isikhathi esifushane sokuphumula) noma isimo sezulu esibandayo.
