摘要
The present invention relates to a semi-rigid pavement method, cement milk used in the method, and a construction method for injecting the cement milk. The semi-rigid pavement method of the present invention comprises the following: installing and pounding aspha and injecting the cement milk into pores of the asphalt. The injection of the cement milk into the pores of the asphalt is promoted by applying vibration to the cement milk. An injection material for the cement milk used in the present invention fills the pores of an asphalt paving material, and is formed of 50-90 wt% of chloride resistant cement, 3-30 wt% of rapid curing agent, 0.1-5 wt% of superplasticizer, 0.01-1.0 wt% of thickener, 1-15 wt% of silica fume, 1-12 wt% of expanding agent, 0.1-2 wt% of hydration promotor, and 0.1-3 wt% of hydration retarder. The expanding agent is in a liquid form, and is at least one compound selected from polyoxyethylene alkyl aryl ether, a polyoxyethylene oxypropylene block copolymer, polyoxyalkylene glycol, and alkyl or cycloalkyl polyoxyalkylene. 0.1-3.0 wt% of expanding agent is mixed for the chloride resistant cement.
