Aggregate and binder application rate with different number of passes for surface dressing performance
Surface dressing is a very useful and cost effective process for restoring skid resistance to a road surface that is structurally sound. In the new roads adequate surface texture is designed in the running surface by specifying requirements for both aggregate properties and texture depth. The object...

| Summary: | Surface dressing is a very useful and cost effective process for restoring skid resistance to a road surface that is structurally sound. In the new roads adequate surface texture is designed in the running surface by specifying requirements for both aggregate properties and texture depth. The objective of this study is look on the effect of aggregate application rate, binder application rate and number of passes on surface dressing performance. This study involves 6, 10, and 14mm size of aggregates. All the aggregates were laid with penetration grade 80-100 bitumen. Skid resistance and texture depth were measured by British Pendulum Test (BPT) and Sand Patch Test (SPT). Results were analyzed using analysis of variance (ANOVA) using (Minitab15) to justify the objectives. The result showed that 14mm generated higher skid resistance and texture depth. |
