Cores from concrete pavements that had been exposed to rain while plastic, and specimens prepared in the laboratory and exposed to artificial rain showers, were tested for abrasion and skid resistance. Companion non-rained-on cores and laboratory specimens were similarly tested. The results indicated that average skid resistance measured with the British portable tester was similar on both rained-on and non-rained-on cores and specimens. Full-scale tire skid numbers were about ten percent higher on non-rained-on untraveled pavement sections than on adjacent rained-on sections. Scaling due to freeze-thaw exposure, and abrasion loss determined using the U.S. Corps of Engineers procedure CRD-C52-54, were consistently higher on rained-on than on comparable non-rained-on cores and specimens. Abrasion loss was higher on untraveled pavements than on those that had been in use for several years. Also, abrasion loss was higher on specimens that had been exposed to heavier rain intensity, longer rain duration, and deeper texturing. Comparison of abrasion loss, scaling due to freeze-thaw exposure, and frictional BPT numbers on non-rained-on and rained-on cores from untraveled pavements and on similarly prepared specimens indicates that abrasion and BPN can be predetermined from specimens made and tested in the laboratory. Two abrasion machines made to the specifications of the Corps of Engineers procedure gave two different levels of abrasion loss on paired specimens, but the resulting trends were similar. (FHWA)
