(Review requested)

The deleted "pavement" was a separately mapped cycleway, originally added from DfT data in 2013.

In general, deleting another mapper's work should only really be done if the feature doesn't exist, or no longer exists. However, from the Bing aerial and street side imagery, it looks like the asphalt pavement on the W side was incorrectly added as a separate cycle track. This should have been the explicitly shared pavement/cycle track paved with red bricks on the E side. I would be inclined to map the E side as a separate way, as it joins Chadwick Road at a different point to the carriageway of George Raymond Road and is clearly a continuation of the shared cycle track through Pirelli Park.

If you don't want to do that, the segment of George Raymond Road between Chadwick Road and Pirelli Park should be tagged with:

cycleway:left=track
cycleway:left:oneway=no
cycleway:right=no
sidewalk:left:surface=paving_stones
sidewalk:right:surface=asphalt
