THE EXPERIMENTAL RESEARCH ON REFLECTIVE CRACKING INHIBITION EFFORT USING NON-WOVEN FABRIC

Takaharu NISHIKAWA, Tatsuaki NIHISGATA, Tomio HARA

The overlay is popular rehabilitation works for the existing asphalt pavement or the cement concrete pavement. But at the early stage the reflective cracks caused the cracks of the existing asphalt pavement or the joints of the cement concrete pavement. We selected the inhibition process using non-woven fabric for reflective cracking that process was easy way at the overlay rehabilitation works. On this report we mentioned the method of establishment for optimum tack coat content, the inhibition efforts of reflective cracking on the laboratory tests, and the evaluation of inhibition efforts from the follow ups on the field.
