Abstract

Objective of this research is development of slurry seal with Reclaimed Asphalt Pavement (RAP). There found out that, RAP is dense graded, and its size is larger than crushed dust many times. So, when the proportion of RAP is higher than 40 percent then aggregate size is not pass standard. Proportion and RAP and crushed dust is designed to 4 groups such as 0:100, 10:90, 20:80, 30:70 and 40:60 for Para Slurry Type 3. We found out that Mix Time are 144-158 s, Set Time are 6-15 s, Cure Time are 47-93 s, Track Abrasion are 126.67-174.37 gm/m2, Field Stability are 982.17-1,512.09 kg and Skid Resistance are 67.0-72.2. We can conclude that RAP is the possible material to mix with crushed dust for Slurry Seal. The maximum of RAP is 20 percent of aggregate. Engineering properties are not excellent because of we use recycled material but they pass standard of Slurry Seal, and it is full recycled material.
