Imirima y'ubwatsi bw'ubukorano igenda irushaho kuba ikintu gisanzwe kandi ikoreshwa mu mikino ya buri munsi. Sisitemu yuzuye y'imikino y'ubwatsi bw'ubukorano igizwe ahanini n'urwego rw'ibanze, urwego rwo gupfuka, n'urwego rw'ubwatsi. Urufatiro si imwe mu ntambwe z'ingenzi mu gushyiraho ubwatsi bw'ubukorano gusa ahubwo runakora nk'urufatiro rw'umurima wose. Ubwiza bwabwo bugira ingaruka zitaziguye ku mikorere n'ubuzima bw'umurima. Kubwibyo, ni ngombwa gushyira imbere ishingiro ry'imirima y'ubwatsi bw'ubukorano. Hasi aha hari incamake y'ubwoko bwinshi bw'ishingiro busanzwe bukoreshwa mu mikino y'ubwatsi bw'ubukorano.
1. Umusingi wa sima ya beto
Ubugari: Igipimo cyo kunyura mu buryo bugororotse kigomba kuba kiri hejuru ya 95%, hamwe n'ubushobozi bwo kwihanganira 3mm ku gikoresho cya metero 5.
Ubuhaname: 3‰-4‰ hagati, hamwe n'igishushanyo mbonera cy'amazi yo mu bwoko bwa turtleback. 8‰ ku mirongo, 5‰ ku mirongo igororotse, na 5‰ ku bice bigize uruziga. Ubuso bugomba kuba buringaniye, bworoshye, kandi buvomera amazi neza.
Ingufu n'Ubudahangarwa: Ubuso bugomba kuba bumwe kandi bukomeye, budafite imyanya cyangwa impande zacitse, bufite ingingo zigororotse kandi zoroshye. Katamo ibice bya metero 6 x metero 6. Igice cyo hasi kigomba gupfunyika ku bucucike burenga 95%. Nyuma yo gukoresha icyuma gikomeye, menya neza ko ubuso budafite ubutaka butose n'ibimenyetso bigaragara by'uruziga.
Igihe cyo kubungabunga: Igihe cyo kubungabunga umusingi ni iminsi 21.
Aho ishyirwa: Kugira ngo yubakishe neza kandi ushyireho ikimenyetso, koresha ibimenyetso bikomeye kandi bisobanutse neza kugira ngo ushyireho ikimenyetso ku mirongo yose iri aho hantu.
2. Ishingiro rya Asphalt
Ubugari: Igipimo cyo kunyura mu buryo bugororotse kigomba kuba kiri hejuru ya 95%, hamwe n'ubushobozi bwo kwihanganira 3mm ku gikoresho cya metero 3.
Ubuhaname: <1% mu buryo butambitse, <1‰ buhagaze, na <4‰ mu gace gafite uburebure. Ubuso bugomba kuba buringaniye kandi bunoze kugira ngo amazi asohoke neza.
Ingufu n'Ubudahangarwa: Ibikoresho bya Asphalt byaba byiza bitarimo ishaza cyangwa bidakoresha ishaza nkeya. Ubuso bw'ifatizo bugomba kuba bufatanye neza kugira ngo habeho ubuso bworoshye, budafite icyuho, budafite impande zaboze, kandi bufatanye neza kandi burambuye.
Igihe cyo kubungabunga: Igihe cyo kubungabunga umusingi ni iminsi 28. 3. 37 Umusingi w'ubutaka bwa Lime
Ingano y'ibikoresho: Ubutaka bugomba kuba ubutaka bw'ibumba bufite ingano ntoya itarenze mm 15, ingano ya sulfate iri munsi ya 0.8%, n'ingano y'ibintu bikomoka ku bimera iri munsi ya 10%. Koresha ifu y'indimu ihumura neza nibura yo mu cyiciro cya gatatu. Nyuma yo guhitamo ubutaka n'indimu byabugenewe, kora ikizamini cya 3:7 cyo gupima ubutaka bwa lime buri metero 5.000 (gupima cyane) kugira ngo urebe ko ubuziranenge bw'inyubako bugenzurwa.
Ubushyuhe: Kugenzura ubushyuhe ni intambwe y'ingenzi. Muri rusange ni byiza kugumana ubushyuhe buri hagati ya 20% na 23%, ntarengwa butarenze 24%. Mbere yo kubaka, ibipimo nk'urugero rw'ubushyuhe bw'ubutaka, ubugari bw'ubutaka n'ishwagara, hamwe n'ingano ya tamping na rolling coefficient bigomba kugenwa hashingiwe ku miterere y'umushinga, igipimo cy'ubushyuhe cyagenwe, ubwoko bw'ubutaka, n'imiterere y'ubwubatsi.
Igipimo cy'ingufu: Igipimo cy'ingufu K ≥ 0.95
