The 1.74-mi-long project -- Project M 1186(2) -- consisted of two experimental sections 3 and 4 in. thick. In addition, a 500-ft test section was included where no bonding grout was used before overlaying, as well as another 500-ft test section where a 6-in.-wide tape was placed over the old transverse joint instead of inserting backer rod into the joint. Four different methods of reinforcement stabilization of severe cracks were tried on the project, ranging from bars inserted in sawed slots in the old pavement to bars placed on chairs. The project exhibited over 5,800 ft of random centerline cracking immediately after construction due to a combination of factors. Very little random cracking has occurred at transverse joints and the degree of reflection cracking exhibited by the project after one year of service is minimal. Although the unit cost of $25.14/sq yd is somewhat excessive, the excellent performance of the project since construction, as well as the dramatic decrease in pavement deflection and roughness and increase in skid resistance, show this method of rehabilitation to be a viable alternative to asphalt overlays or complete reconstruction.
