This driveway was poured last summer. I was out of town when it was poured, and arrived home that evening. It was a hot day and the surface did dry out before I had a chance to get the hose on it. After that I kept it very wet constantly for about 2 weeks. During that period, I did notice some hairline cracks that were visible when I was wetting it, I have attached some pictures of those web-like hairline cracks. I wondered if that was because I let it dry out too much at the start.
I just noticed these little spalls peppered all over the surface. It seems that the spalls are occurring directly over aggregate. I've attached a few pictures of the little spalls. To me it appears that the surface is starting to break down.
I'm wondering if the spalls are due to my failure get on the wet cure early enough, or perhaps due to over finishing? Also, whether there is anything I can do to prevent further breakdown of the surface?
