Yes, but not great.
OpenStreetMap has surface information for roads and doing a quick survey of other known roads suggests it's moderately accurate, but there is no guarantee it is correct.
Case in point for a recent trip of mine - Wolgan Road has a surface listed as "unpaved". The majority of this road is actually paved, and only the last 9 km is unpaved.
To retrieve this information, find the road of interest, right click and choose "Query features". Select the road's name from the list that appears and it will have a property of "surface" to review.
