PAVEMENT EVALUATION: TEST FREQUENCY REQUIREMENTS FOR DEFLECTION BOWL PARAMETERS

Pavement management is divided into network and project level studies. Fundamental to the effective management of roads in a network or project level study is the evaluation of the functional as well as the structural condition of the road through the testing of the road. Several tests are available for use from which pavement characteristics can be obtained. These tests differ in terms of the type of information that is measured as well as the cost of obtaining the information. The cost of the information is a function of the required test frequency. This paper investigates the requirements of the evaluation of pavements as a basis to establish guidelines for test frequencies. A statistical procedure is presented which can be used to determine the minimum number of tests required to establish pavement characteristics at a certain level of confidence. The procedure is used to develop guidelines for the test frequency requirements for deflection bowl parameters, the measurement of which is internationally used for the structural evaluation of pavements.
