Book Description
The project evaluated numerous repairs on portland cement concrete pavements and bridge decks made with a number of laboratory accepted, proprietary patching materials and portland cement concrete mixtures of different designs. It was ascertained that in the majority of cases when the patches failed, the failure resulted from the use of improper construction techniques, not from deficiencies in the patching materials used. Of the three proprietary materials determined not to have performed satisfactorily Embeco 411A, a magnesia phosphate material, has been used for 10 years. Fondu, a high alumina concrete material, and Duracal, a calcium sulfate material, performed so poorly that use of the former should be limited to small patches and use of the latter should not be allowed. In addition, it was ascertained that portland cement concrete incorporating carefully chosen admixtures can provide satisfactory service at a lower cost than proprietary patching materials. Upon reviewing the May 1984 final report the FHWA suggested several changes. Those changes have been incorporated into this revised version.
