• Abstract:
  Portland cement concrete (PCC) is the world’s most versatile construction material. PCC has ; been in use in the United States for over 100 years. PCC pavement is generally constructed as ; either continually reinforced concrete pavement (CRCP) or jointed plain concrete pavement ; (JPCP). CRCP is constructed with steel reinforcing totaling about 0.7 percent that is intended ; for crack control and to provide load transfer once cracks have formed by keeping crack faces ; in close contact. JPCP is constructed from unreinforced concrete with steel dowel bars over the ; saw-cut joints to provide load transfer between slabs. CRCP has the advantage of not having ; joints, which leads to better ride quality and generally longer life, if constructed properly. JPCP ; is advantageous because it generally costs about 20 percent less than a comparable CRCP ; section. The major drawback to JPCP is the joints. The relatively large saw-cut joints produce ; more noise generation than CRCP, and create points for water movement into the pavement ; structure. Recently, it has been noticed on a wide scale within the United States that a great ; number of JPCPs in the 15-25 year age range are exhibiting spalling and severe deterioration ; at the joints. Various theories are being explored nationally to explain the causes of premature ; joint deterioration, but all fall into the categories of unwanted moisture at the joint locations or ; damage caused in the sawing process. Concrete is durable and premature joint deterioration is ; unacceptable, as the intended design life of many of these pavement structures is 30-40 years. A ; need exists to produce a jointless pavement with the high cost of CRCP.
