求翻译：且空隙较大，层间有水分滞留，面层底部的集料松散脱落，脱落的骨料基本没有沥青裹附，而中面层较密实，无明显病害，是什么意思？

And a larger gap, between the water retention layer, the surface layer of loose material off the bottom of the set, off the asphalt aggregate base is not wrapped with, while the more dense surface layer, no obvious disease,

A relatively large gap between the floors, and there is moisture, surface layer stranded at the bottom of the loose aggregate fall off, the galvanizer fell off basic there is no asphalt surface layer wrapped in a schedule, and compacting, no obvious lesions.

Also the crevice is big, the level has the moisture content detention, the surface layer base aggregate falls off loosely, the aggregate which falls off does not have the asphalt to bind basically attaches, but the surface layer is dense, not obvious plant disease,

And the gap is large, moisture retention between layers, surface of aggregates at the bottom of loose particles from the peeling of aggregate basic no asphalt wrapped, and layer in a compact, no obvious defects,
