There is now more to be considered than just price and getting those cracks filled. Rubber Asphalt Crack Sealants have been on the market for 29 years and to meet ASTM D-5078 specifications. Rubber Asphalt Crack Sealants that are made with 80% Asphalt Concrete and 20% ground tire rubber have always been excellent sealing materials.
Limestone dust has no structural or bond characteristics. It is only used to pass tests and lower the cost per pound of material. It is also very unsafe when allowed to surface on your highways. Please read the "Purport" in D-5329-96 Sealants and Fillers for cracks in Asphalt and Concrete Pavements. If ASTM remove the responsibility from their shoulders and places that responsibility on yours shoulders, maybe you should look at ASTM D-6690 materials for skid tests.
Do you know that most suppliers of the crack sealing products on the market today use up to 60% limestone dust as a filler? Limestone dust and polymer plastic is very slick when we and increases the chances of motorcycle crashes.
Do you know that our manufacturing company is the only one that does no use limestone dust or polymer plastic in making our products?
The ASTM testing specification for D-1190 and D-6690 carry a disclaimer that shifts the responsibility to the end user. In simple terms this means Highway departments (both Federal and State), Cities, Counties, and Property Owners.
Safety is not the responsibility of the manufacture even though they do design material with very low skid numbers. I think it is time to look at these products and demand higher skid numbers that are equal to the asphalt pavement or concrete pavement.
WHY GIVE THIS MONEY AWAY?
Today we buy by the pound but all material is placed by the gallon.
