LOAD TRANSFER AT TRANSVERSE CRACKS IN CONTINUOUSLY REINFORCED CONCRETE PAVEMENT

Performance of Continuously Reinforced Concrete Pavement Containing Recycled Concrete Aggregate

In 1995, the Texas Department of Transportation (TxDOT) began reconstruction in Houston on a section of IH-10 with continuously reinforced concrete pavement (CRCP). The unique aspect of this project was the use of crushed concrete as both coarse and fine aggregates in the new concrete. No virgin aggregates were used. The primary objectives of this study were to evaluate (1) the material propert...

Sensitivity analysis frameworks for mechanistic-empirical pavement design of continuously reinforced concrete pavements

The new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) performance predictions for the anticipated climatic and traffic conditions depend on the values of the numerous input parameters that characterize the pavement materials, layers, design features, and condition. This paper proposes comprehensive local sensitivity analyses (LSA) and global sensitivity analyses (GSA) methodologies...

Flexural Cracks in Fiber-Reinforced Concrete Beams with Fiber-Reinforced Polymer Reinforcing Bars

Fiber-reinforced polymer (FRP) reinforcing bars have aTtracted considerable 0llellli0l1 for applications where corrosion of steel reinforcement is problemaric. Due 10 rhe generally low elastic modulus and poor bond clwracreristics of FRP as coil/pared 10 steel reinforcing bars, the use of FRP results in IGI:i?er crack widlhs under senJice loads. Fiber-reinforced concrete (FRe) is proposed for u...
