Standard Definitions for Common Types of Pavement Cracking 26 C H A P T E R 3 Role of Cracking Data in DecisionMaking Processes Introduction This chapter reviews the SHAs applications of cracking data for both network and project level decision-making, and also the acceptable levels of precision and bias for collected data based upon the relative impact of a crack type. This includes how cracking data are used for pavement management, and which crack type(s)
