A resume of field behavior of some 440 miles of concrete pavement constructed for experimental purposes by New York State with different proportions and combination of aggregates. Field service records of these pavements were made and compared with laboratory tests of aggregates used. The purpose was to study the durability of cement concrete pave-ment as affected by coarse aggregate such as stone, 1 gravel, and slag; as affected by sands of different characteristics, such as high and low kaolin; and as affected by blended cement composed of different proportions of natural and normal portland cements. The projects studied, identified by name and listed.
