Report No. 3 on a Concrete Pavement Without Transverse Joints

This is the third report of observations and operations pertaining to a concrete pavement without the usual transverse joints constructed in the summer of 1949. Report No. 2 which was presented to the Research Committee December, 1949, contained a detailed description of the project, pictures of the class of cracking described, a record of the crack filling operation to December, 1949, and three crack survey reports with a strip map of the project. The purpose of this report is to present three additional crack surveys taken in 1950 with the additional crack filling operations up to this time. All of the ungrooved cracks were cut out and filled with various types of fillers late in the past year, so that this type of treatment has been extended throughout the project
