چکیده انگلیسی
Chip-sprinkling cement concrete (CSCC) pavement can provide satisfactory friction and has potential for noise attenuation due to its exposed surface texture, making abrasion resistance significant. The abrasion resistance of CSCC pavement was evaluated using the Cantabro test method, with smooth surface concrete as the control group. This method uses a Los Angeles Abrasion Machine without steel balls. Using the same method, the abrasion durability of CSCC was also assessed using different concentrations of sodium chloride solutions. The effects of different water/cement ratios and chip-sprinkling parameters were analyzed. The latter variables included aggregate particle size, aggregate spreading area ratio, and aggregate pressing depth ratio. Data indicate that the abrasion losses of CSCC specimens change quickly at first, but later they change more gradually. Aggregate particle sizes of 9.5-13.2 mm may be better when just considering the effect of aggregate particle size on the abrasion resistance. Abrasion losses of CSCC specimens multiply with increasing aggregate spreading area ratios and decrease with the rising aggregate pressing depth ratios. On the whole, abrasion resistance of CSCC is superior to the smooth surface concrete in the control group.
