Ua ntej, siv 28 rau lub ru tsev × 35mm tuab cement mortar leveling.

Ua ntej txheej txheej ntawm asphalt pobzeb, nrog rau cov nplaum sab saum toj, thiab ncaj qha pav rau ntawm lub ru tsev raws lub ru tsev nqes hav hauv qab. Nyob rau ntawm ib kawg ntawm cornice ntawm lub hauv paus ntawm phab ntsa, thawj txheej ntawm asphalt pobzeb txuas mus rau 5 mus rau 10 mm. Txhim kho hauv av nrog tus ntsia hlau 50.8 hli los ntawm hauv qab ntawm ob qho kawg thiab 25.4 hli los ntawm sab, thiab tom qab ntawd muab nws sib npaug hauv kab rov tav ntawm ob tus rau tes. Muab 2 ntsia hlau thiab ntes kab rov tav.

Tso thawj txheej ntawm asphalt pobzeb, so tawm 167 hli ntawm thawj txheej asphalt pobzeb, thiab tom qab ntawd nteg tag nrho asphalt pobzeb. Teem thawj asphalt cib raws qhov kawg ntawm phab ntsa thiab ntug ntawm thawj txheej ntawm asphalt cib raws cornice. Kho nrog rau cov ntsia hlau ntawm 60.8 hli los ntawm ob qho kawg mus rau hauv qab thiab 35.4 hli los ntawm sab, tom qab ntawd teem ob lub rau tes ntxiv nyob rau hauv kab rov tav kev taw qhia ntawm ob lub rau tes thiab snap kab rov tav.

Tso ob txheej ntawm asphalt pobzeb. Sab ntawm thawj txheej ntawm asphalt ntsib cib ntawm txheej thib ob yog staggered los ntawm ib nrab ntawm nplooj los ntawm sab ntawm thawj txheej ntawm asphalt ntsib cib. Hauv qab ntawm ob txheej ntawm asphalt pobzeb yog yaug nrog rau sab saum toj ntawm cov hniav sib koom ua ke ntawm thawj txheej ntawm asphalt pobzeb. Siv cov kab kab rov tav snapped rau thawj txheej ntawm asphalt pobzeb ua rau hauv qab ntawm txheej thib ob ntawm asphalt pobzeb sib npaug rau cornice, thiab kho cov txheej thib ob ntawm asphalt pobzeb nrog rau tes.

Npog peb txheej ntawm asphalt pobzeb, txiav tag nrho cov hniav ntawm thawj txheej asphalt pobzeb ntawm peb txheej asphalt pobzeb, stagger nws nrog thawj txheej ntawm asphalt pobzeb ntawm ob txheej asphalt pobzeb, ua rau hauv qab ntug ntawm lub thib peb txheej ntawm asphalt pobzeb yaug nrog rau sab saum toj ntawm cov hniav sib koom ua ke ntawm lub thib ob txheej ntawm asphalt, tag nrho cov txheej thib peb ntawm asphalt zoo. asphalt pobzeb.

Muab cov vuas asphalt rau ntawm lub qhov dej. Cov vuas asphalt ntawm cov ru tsev sib tshuam yuav tsum tau muab tso rau hauv lub qhov dej ntawm tib lub sijhawm, lossis txhua sab yuav tsum tau ua kom sib cais, thiab yuav tsum tau muab tso rau ntawm qhov nruab nrab ntawm txoj kab nruab nrab ntawm 75 hli. Tom qab ntawd muab cov pobzeb asphalt mus rau pem hauv ntej ntawm ib lub ru tsev eaves thiab txuas mus rau lub gutter, kom lub gutter asphalt pobzeb zaum kawg ntawm txheej txuas mus rau lub ru tsev uas nyob ib sab kom ntev li 300 hli, thiab tom qab ntawd pav lub gutter asphalt pobzeb raws li lub ru tsev eaves uas nyob ib sab thiab txuas mus rau lub gutter thiab yav tas los nteg cov kua nplaum ua ke. Lub trench asphalt pobzeb yuav tsum ruaj khov nyob rau hauv lub trench, thiab trench asphalt pobzeb yuav tsum tau kho los ntawm kev kho thiab sealing lub trench.

Thaum tso cov vuas asphalt, ua ntej me ntsis kho qhov kawg ob peb asphalt vuas uas tau muab tso rau ntawm ob sab saum toj ntawm qhov inclined ridge thiab lub ridge, kom cov pob zeb asphalt tag nrho npog cov vuas saum toj kawg nkaus asphalt, thiab qhov sib tshooj dav ntawm cov ridges ntawm ob sab ntawm lub ridge yog tib yam. Tom qab tus ntsia thawv yog tsau, lub tsho tiv no cov pobzeb uas raug asphalt nrog asphalt kua nplaum.
