PORTLAND CEMENT CONCRETE PAVEMENT PATCHING _____ Portland cement concrete pavement patching consists of the removal and replacement of unsound concrete, either full depth or partial depth. The following items are discussed in this chapter: 1) Materials and the composition of patching concrete 2) Removal of unsound concrete
The specification for accelerated concrete pavement patching addresses the use of rapid setting concrete materials in a pavement repair application. It is intended to be used when project circumstances, including business and industrial settings, warrant the use of concrete patch materi al which will allow an early opening to traffic.

Patching concrete pavements with concrete is best because, when properly done, patches are integral with the pavement and not inferior to the original slab. Procedure and methods of construction. Based on extensive experience records, are discussed under the headings: slab thickness, removal of old slab preparation of subgrade, materials and ...
Materials and methods for patching portland cement concrete (PCC) pavements are discussed. Distinction is made between full-depth patches and the more common "pothole"-type patch. The evaluation of five materials to be used for pothole patching in PCC pavements are presented and discussed in terms ...
