The McLeod design method recommends reducing the binder application rate by up to 0.06 gal/sy for a flushed or bleeding surface (McLeod 1969). AChip Seal Design Methods (1) North America (Ranked by prevalence) •Empirical / Past Experience •No Design •Own Method •McLeod (1960s) / Asphalt Institute •Kearby (1953) / Modified Kearby •Hanson (1934 / 1935)(Obsolete)The McLeod design method shall be utilized in determining application rates.
