Maximum w/c for concrete used for pavement, sidewalk, and curb
Maximum w/c for concrete used for pavement, sidewalk, and curb
(OP)
I am a roadway designer and typically write specifications using the Greenbook. I recently had a construction manager reject a concrete pavement submittal because he thought the w/c of 0.57 was too high (even though the concrete compressive strength and slump was met) and recommended that it be under 0.45. The w/c was adequate based on the aggregate grading, slump and table 201-1.3.3(A) of the Greenbook. I typically don't modify the Greenbook unless I know exactly why I am doing it. Does anyone have an opinion on why a lower w/c ratio is benificial?
Thanks,
Thanks,

A lower w/c ratio will result in a more durable mix, capable of withstanding abrasion and abuse that are common for pavements.
