| Abstract: | On the basis of first limitation load of load-transfer condition and correlated deflection, the method that identify void of rigid pavements using deflection data measured from falling weighting deflect meter is put forward. According to application on test road, it is believed that the method is reasonable. A kind of squeezing material is developed on the basis of large amount of tests. This material has the properties of good self-flowing density, high earlier strength, non-segregation, non-bleeding and non-contractility and it can meet the requirement of mud jacking. At the same time, its construction technology and quality assurance measure are discussed. |
