A COMPREHENSIVE STUDY OF COLD CLIMATE AIRPORT PAVEMENT CRACKING (WITH DISCUSSION)

The basic purpose of the study reported in this paper was to develop cracking prediction models for design and to assess the feasibility of using proposed new asphalt specifications for controlling the cracking problem on Canadian airport pavements. More specifically, the objectives were as follows: (1) Carry out laboratory tests on core samples from the 26 airports selected for study (bulk density, coefficient of thermal contraction, low-temperature stiffness at -35 deg C, -18 deg C and 0 deg C, binder content, and penetration and viscosity on the recovered binders); (2) Acquire crack survey results plus other available design and construction data from the 26 sites; (3) Build a computerized data base for the data collected; (4) Carry out analyses for relating cracking to the independent variables measured or acquired, using the data base developed; and (5) Evaluate the applicability of the proposed new Canadian General Standards Board specifications for asphalts with regard to selecting materials for preventing or minimizing cracking. In addition, the scope of the study provided for any other relevant observations on pavement performance, importance of other variables and recommendations for follow-up work.
