| From cement pavement and asphalt pavement early disease investigation, interlayer pavement and small interlayer bonding or adhesive power is one of the important reasons of pavement early damage. Therefore, the cement concrete pavement and asphalt concrete pavement base and subbase and surface of early preventive maintenance, fill the interlayer bonding between pavement and reinforcement layer, improve overall carrying capacity of the road, closed, cracks on the surface to prevent moisture infiltration in the pavement structure layer, can greatly reduce the late road damage, prolong the service life of road.To this end, this paper on the basis of the research at home and abroad such as cement grouting, indoor experiment, optimized various performance indicators, successful in research and development for pavement structure reinforcing polymer grouting material. Its performance than traditional cement grouting material has many advantages: such as good flowability, high strength, short setting time, little secrete water and contractility.Combining the theoretical analysis and test of engineering inspection, the land trenchless structure reinforcing polymer grouting reinforcement and disease treatment construction technology research, to determine the construction technology of the polymer grouting technology and grouting construction design parameters(grouting pressure, grouting hole layout form, grouting hole spacing, etc.). Through real engineering application research, the paper puts forward to polymer grouting treatment acceptance standard of construction quality.Based on real engineering, through the study of the trenchless type of pavement structure reinforcement and treatment of these diseases, and the old road to get a more thorough treatment of these diseases, and improves the residual strength of pavement disease place, and the disease of pavement performance to achieve the same roads in good condition after the treatment the road technology standard. The grouting treatment technique for disease treatment targeted, short time to repair, maintenance costs than traditional process significantly reduced, for large traffic volume of highway maintenance has obvious social significance and economic benefits, the reinforcement method is an effective way. |
