The following is an example illustration of how material cost-effectiveness can be computed using the worksheet provided. In the exercise, two different treatment options are being considered by an agency for an AC transverse crack sealing project.
Rubberized asphalt, unit weight = 1.14 kg/L or 1,140 kg/m3. Standard recessed band-aid configuration. Material and shipping cost: $1.43/kg. Estimated production rate: 762 lin m of crack per day. Estimated service life: 3 years. Low-modulus rubberized asphalt, unit weight = 1.07 kg/L or 1,070 kg/m3. Shallow recessed band-aid configuration. Material and shipping cost: $1.90/kg.
Estimated production rate: 915 lin m of crack per day. Estimated service life: 5 years.
