Pavers are superior to other surface types because the end result is made of individual stones which can move and be reset if an area needs to be repaired. Pavers interlock and thus require no mortar to stay in place. As an interlocked system of individual stones, pavers move with soil's swelling & contraction like no rigid stone system would ...

The contractor proposed replacing the paver-placed surface treatment with a micromilling process complete with a thin lift HMA overlay. This process was then completed with a Roadtec RX-70 full lane machine with a 4-wrap drum in downcut mode. The thin lift overlap was a 6.3mm HMA mixture using a PG64-22P polymer modified binder.
This deeply penetrative protective treatment may penetrate through exposed stone, tile, grout, or paver surfaces and react with the membrane to mobilize objectionable staining. Always pretest to ensure desired results. Surface and Air Temperatures Surface and air temperatures should be 40–90°F (4–32°C) during application. Higher temperatures
solution is to not get into the problem in the first place. AGGREGATE ISSUES When a seal coat or surface treatment loses its rock, flushing and/or bleed-ing will be the result. Aggregate issues include rock loss, application of too much rock, use of dirty rock, use of soft rock, and judicious use of modified aggregate grades. BINDER ISSUES

Chapter 6: Technical Guidance for Specific Treatment Measures 6-45 Overview Description Pervious pavement types include pervious concrete, porous asphalt, permeable pavers and pervious pavers. Pervious pavers allow infiltration through the paver while permeable pavers utilize the joint space between the pavers for infiltration.
Installing pavers incorrectly can lead to permanent foundational issues in the pavers such as cracking, crumbling and chipping. One of the most common ways pavers are substandardly installed is by not packing down the base beneath them. If pavers are simply placed on an uneven surface, their chances of cracking are tremendously higher. 3.
