D-Cracking in Portland Cement Concrete Pavements

A study was conducted to determine the mechanisms involved in the Iowa Pore Index Test and investigate ways to modify and supplement the testing procedure to increase its accuracy and sensitivity. In the study a modified IPIT was developed which utilizes chamber pressures up to 1379 kPa (200 psi). Instead of using the volume of water entering the aggregate pores over a specified time period the degree of saturation which occurred in the aggregates at various chamber pressures was used. Relationships between degree of saturation and chamber pressure were developed and found to provide a general index of the aggregate freeze-thaw durability properties.
