PA-300_Concrete_Pavement.pdf

This document is a City of Pittsburgh construction standards drawing (DWG No. PA-300) detailing specifications for concrete pavement construction. The technical drawing provides a cross-sectional view of a concrete pavement structure, specifying precise layering and material requirements for road infrastructure projects. The diagram illustrates a multilayered pavement section including a compacted sub-grade, 8" compacted 2A aggregate sub-base, a 10" minimum concrete base course, and a 6 x 12 - W7 x W4 concrete layer, all designed to meet PennDOT Publication 408 and City of Pittsburgh construction standards.

The technical specifications outline critical construction requirements, including using rigid base course with Pendot Type "A" concrete at 4000 PSI strength, compacted aggregate sub-base, and specific reinforcement and joint construction guidelines. The drawing references the City of Pittsburgh Standard Details of Construction for Street Pavements (Revision November 2008) and provides detailed notes on material composition, compaction standards, and construction methodology. This drawing appears directly related to the City of Pittsburgh's brick roadway renovation project, providing the technical infrastructure specifications for potential bidders and contractors involved in street reconstruction efforts.
