Pavement Manual: Concrete Pavement Repair Search

Use Item 720, “Repair of Spalling in Concrete Pavement,” or Item 721, “Fiber Reinforce Polymer Patching Material,” for situations where the deteriorated concrete is shallower than the mid-depth of the slab. For emergency work or temporary repair, Item 700, “Pothole Repair,” may be utilized. Anchor: #i1005109.

This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more
