Project Details

Project Description: 

This project will integrate pavement performance databases with highway safety information systems, and analyze the data to develop crash modification factors and pavement management strategies that include safety.

Goals:

  • Prove that pavement surface characteristics are the most important factors affecting the number of fatal and disabling injury crashes. 
  • Prove that rigid pavements have lower crash rates than flexible pavements.  
  • Demonstrate that the concrete mixture proportions associated with higher strength concretes have lower friction numbers and that an intermediate strength provides the optimum performance in terms of safety and distress.
  • Demonstrate that recycled asphalt concrete pavements have lower friction numbers.
  • Prove that the current state-of-the-art method to develop Crash Modification Factors (Empirical Bayes) yield inaccurate numbers for pavements.
