Applicability of Precast Concrete Pavements with Doweled Joint to Tunnel Road

Applicability of precast concrete pavement (PRCP) with doweled joints to tunnel roads was investigated. The effects of subbase and dowel bars at transverse joints on the mechanistic behaviors of PRCP were examined. The thermal stresses in PRCP were also discussed. Fatigue and faulting analyses were conducted to compare the fatigue damage and amount of faulting of PRCP with those of normal concrete pavement (NCP). From the results of the analyses, it was found that increasing flexural strength of concrete and modulus of subbase reaction is required to ensure long term performance of PRCP.
