Concrete Pavement Joint Study - 1965
The major design features included in five projects were (1) sawed versus formed transverse joints, (2) time interval between concrete placement and joint sawing, (3) plain versus reinforced concrete pavement, (4) joint spacing, (5) depth of transverse saw cut and (6) thickness of cement-treated subbase. The design features were primarily evaluated in terms of transverse, longitudinal and diagonal cracking of the pavement slabs. This evaluation considered the effects on cracking of such factors as soil characteristics, concrete mix and strength, air temperature and traffic density. Conclusions: (1) Concrete pavements with sawed joints are as resistant to cracking as those with formed joints. (2) plain concrete slabs of 25 feet are as resistant to cracking as those of 20 feet. (3) Optimum time for sawing transverse joints is from 12 to 24 hours after placement of concrete. (4) A 1 1/2-inch deep saw cut appears to be adequate for transverse joints in 8-inch thick concrete pavement. (Author)
