Hoangminh90,
I think your Capt was right.
References:
-Definition of Damp: ( FCOM PER-TOF-CTA-20 P 1-2 10 SEP 14 )
A runway is damp when the surface is not dry, but when the water on it doesn't give a shiny appearance.
-On take off charts you have a section for wet conditions ( Influence on runway condition )
-On Runway Condition Assessment Matrix for Landing ( QRH PER-C 3-6 10 SEP 14 ) you can also find that Damp and Wet ( up to 3mm of water ) share code 5 for related landing performance. Dry runway is code 6.
