The shear and cleavage tests of cement concrete combining pavement have been done , the fatigue test of the full size slab has also been done. The result indicates that YJ-302 bond has the interface felt more strongly than the cement slurry and the 107 glue cement slurry when the old pavement lS not chiseled. The YJ-302 provides the pavement to be bond well and makes the pavement be combine ent1rety. That Y}-302 is used in combining pavement 1S more economical of money and YJ-302 is good bond at present.
