Two test sections, one on new construction and the other on a maintenance resurfacing project, were installed in the fall of 1980 to evaluate the proprietary product Chem-Crete. Laboratory tests and dynaflect and density measurements were performed on the experimental and control mixes and the performance was evaluated over a two-year period. Raveling was noticed in all sections, especially in the Chem-Crete mix, approximately two months after paving; however, the deterioration appeared to stabilize in all sections shortly thereafter, and traffic healed the surface of the control sections but not that of the Chem-Crete sections. Significant additional cracking and raveling appeared in both Chem-Crete sections after the second winter, whereas the control sections continued to perform satisfactorily
