Rigid Pavement Investigations-Growth Characteristics and Blowups
The main objectives of this investigation are: (1) To measure the 'field growth' of rigid pavements, so that better performing aggregate types can be determined and (2) to determine the reasons for 'blowup' occurrences on rigid pavements. In the field investigation of concrete growth, the overall lengths of all test sites are increasing. To determine the concrete growth the width of the contraction joint were deleted from the overall growth. From this the concrete in two stone contracts appears to be growing, whereas, the concrete on the one gravel concrete appears to be shrinking. The conclusions were drawn from very limited observations and may be typical for all pavements. In the investigation of blowups, the results to date indicate that the probability of a blowup is considerably greater at an expansion joint than at a contraction joint. Also, the probability of a blowup is greater on a pavement built using gravel aggregate than one built using a stone or slag aggregate. Pavement age is also a significant factor in blowup occurrences.
