Application of Ground Penetrating Radar and Grouting Technology in Highway Maintenance
Asphalt concrete pavement has many advantages and is widely used in various levels of highways.During the use of asphalt concrete pavement,due to the characteristics of its materials,cracking diseases caused by dry shrinkage and temperature shrinkage are more likely to occur.Once the asphalt concrete pavement cracks,surface water will seep into the base and roadbed.If not effectively treated for a long time,it may lead to more serious diseases such as reduced base strength and hollowed out roadbed.The simplest treatment method for this type of disease is to excavate the roadbed and pavement structural layers,and fill them layer by layer to the pavement,but this method is time-consuming and requires interruption of traffic.In addition,grouting can also be used to reinforce the roadbed and base layer,and then the road surface can be re constructed to restore traffic operation.During the construction period,traffic can be uninterrupted,and the construction speed is very fast.
