AASHTO PP 90 – Standard Practice for Sand Seal Design
AASHTO PP 90-18 (2020) determines application quantities for applied graded cover aggregate and emulsified asphalt for sand seals on properly prepared bituminous streets. A sand seal is the application of emulsified asphalt following immediately by an application of a single layer of fine graded cover aggregate. The seal may be applied in multiple lifts depending on traffic demands and existing road surface conditions.
