Title:
GEOPOLYMER GROUTING METHOD FOR ASPHALT PAVEMENT IN TEXTILE FACTORY
Document Type and Number:
WIPO Patent Application WO/2019/210445
Kind Code:
A1
Abstract:
A geopolymer grouting method for an asphalt pavement in a textile factory, comprising: performing drilling grouting on an asphalt pavement having a deflection value Ls>20.8; using base grouting, the grouting hole having a depth of 1.2-1.5 m, the grouting pressure being 1.0-1.5 MPa, the unit amount of geopolymer grouting mixing capacity being 90-120 kg/m 2, and the mass ratio of geopolymer to water being 1:0.38; and after curing for three days from the grouting, performing deflection test, wherein if a single point deflection is Ls<20.8, the test is passed, otherwise, performing secondary drilling and grouting construction on the point, so as to make the deflection value of the point meet design requirements. A mixed slurry of geopolymer is injected into a roadbed or a road base through a high pressure pipe by using a slurry pump, thereby achieving a non-excavation reinforcement effect.
