Synchronized gravel yekuisa chisimbiso ndeye kushandisa yakakosha midziyo, iyo inofananidzira matombo ekuisa chisimbiso rori uye yekubatanidza zvinhu (yakagadziridzwa asphalt kana yakagadziridzwa emulsified asphalt) kuti iparadzirwe panguva imwe chete pamusoro pemugwagwa, uye yozoumbwa kuita chinhanho chimwe kuburikidza neakasikwa traffic traffic kana tire roller rolling. . Iro yeasphalt gravel yakapfeka layer, iyo inonyanya kushandiswa seyepamusoro pemugwagwa, uye inogona zvakare kushandiswa pakuvakwa kwepamusoro-soro kwemigwagwa mikuru.

Kuiswa chisimbiso kwematombo kunobata maitiro maviri ekupfapfaidza bhainda uye kubatanidza kupararira pamotokari imwe chete, zvichibvumira zvidimbu zvematombo kuti zvibatane nebinder richangopfapfaidzwa. Panguva ino, nekuti asphalt inopisa kana emulsified asphalt ine fluidity iri nani, inogona kuvigwa zvakadzika mubhainda chero nguva. Iyo synchronous gravel yekuisa chisimbiso tekinoroji inopfupisa chinhambwe pakati pekupfapfaidza kwebinder uye kupararira kwakaunganidzwa, inowedzera nzvimbo yekuvhara yezvikamu zvimedu uye binder, inoita kuti zvive nyore kuve nechokwadi chehukama hwakagadzikana pakati pavo, uye inovandudza kushanda zvakanaka. Inoderedza kuvaka midziyo uye inoderedza mari yekuvaka. Mushure mekunge asphalt pavement yabatwa pamwe chete nematombo ekuisa chisimbiso, iyo nzira ine yakanakisa anti-skid uye anti-mvura seepage zvivakwa. Inogona kurapa nenzira inobudirira zvinetso zvomumugwagwa zvakadai sokuderera kweoiri, kurasika kwezviyo, kutsemuka, kukora, uye kupera. Inonyanya kushandiswa kumigwagwa. kudzivirira uye kugadzirisa kuchengetedza
Iyo synchronous gravel sealing muchina chinhu chakakosha chinosanganisa kupfapfaidza kweasphalt binder uye kupararira kwematombo, kuitira kuti pave nekubatana kwakakwana kwepamusoro pakati peasphalt binder uye aggregate kuti uwane iyo yakanyanya kunamatira pakati pavo.
