Experiments were performed with the British Klarcrete machine-on the Emporia bypass (I-95) in Greensville County to determine if it was capable of removing the top layer of roadway to a depth of between 1/8 to 1/4 inch, and in so doing expose a fresh surface of highly fractured coarse aggregate to give a better skid resistance. In addition, experimentation was performed to determine if the machine could be used as an efficient means of completely cleaning bridge decks of coal tar epoxy prior to resealing. The machine employs 11 percussive hammers mounted side by side and each separated by 2 1/4 inches that strike the pavement approximately 1,500 times per minute and cut a four-foot swath. Each impact removes only a small amount of pavement and in so doing does not injure the surrounding pavement. The sole power requirement is a 600 cubic foot per minute compressor producing 100 pounds per square inch. The machine is self-propelled and its forward speed determines the depth of surface that is removed. The maximum width of surface removal per pass of the machine is approximately 4 feet. In the experiments the machine removed the surface layer of pavement and exposed a new surface of coarse aggregate with fractured jagged edges slightly raised above the surrounding mortar with no irregularities for water to pond and in so doing did not impair the riding quality of the road. Extensive skid testing proved that the skid resistance was raised significantly under specified conditions. The bridge cleaning experiment was successful with the bridge being cleaned more efficiently, faster, ,and with less expense than by sandblasting.

In conducting this investigation, detailed surveys on 85 pavement projects in 7 States were made. These pavements were generally under 15 years old, and reinforced and continuously reinforced pavements. The results of this investigation are contained in the report as prepared by PCA. Some of the aspects of Portland Cement Concrete pavements covered include: 1) Categories and characteristics of PCC pavements; 2) Pavement problems, their causes and required maintenance; 3) A pavement performance and condition survey; 4) A charted summary, design, and construction practices of the states (available separately on request); 5) Construction and maintenance costs, and 6) Design and construction recommendations.
