To find an effective alternative cleaner to remove asphalt, tar, and staining from road maintenance tools and work truck beds.
Date Run:
01/08/2024
Experiment Procedure:
Three pre-weighed stainless steel coupons were assigned to each cleaner. A tablespoon of EZ Street Premium Cold Asphalt was placed on each coupon before sandwiching the contaminated coupon between two steel plates. A mid-size compact car (curb weight: 3,186lbs-3,559lbs) rolled over the steel plates five times in a forward motion to compress the asphalt to the coupons which released the oil and grease to allow the gravel to adhere to the substrate. Dirty weights of the coupons were recorded before testing the cleaners using unheated immersion for 20 minutes with a stir bar set to 200rpm. Once removed, each coupon was wiped with a paper towel to remove the dissolved soil and assess efficacy visually before taking final weights.
