Voids Classification Standard for Cement Concrete Pavement Slabs Based on Service Life
Based on calculation of load stresses at both the middle of the longitudinal joint and the slab corner with various degrees of voids between the slab and the base layer, critical loading load transfer location of slab with voids could be analyzed. According to these data, we have analyzed the effect of voids beneath cement concrete pavement service life. In addition we came out with a void classification standard. Our research shows that, once the pavement has been void, as the void is expanding, the maximum loading position would transfer from the middle of the longitudinal joint to the corner. When the void size Lv is larger than 0.7m, the boundary of void area and no void area becomes the most unfavorable load position. So our void classification standard is as follow: slight degree void when Lv is 0∼0.4m, moderate degree when Lv is 0.4m∼0.7m and severe degree when Lv is larger than 0.7m.
