Patent ID: 8329250

Claim:
A method for applying a crack resistant coating on a surface, where the crack resistant coating increases resistance to high vertical and horizontal movements and high shear stresses on the surface, the method comprising the steps of: applying a binding material to the surface in a volume determined by selecting the binding material and an aggregate mixture; determining a binding material application rate in L/m 2 ; determining a percent binding material residuum for the binding material; determining an amount of binding material adsorbed, where the amount of binding material adsorbed is 0.00 L/m 2 if the surface has been pretreated within three, months and 0.142 L/m 2 if the surface has not been pretreated within three months; determining a percent aggregate mixture air voids based on laboratory tests on the aggregate mixture; selecting a substantially voidless layer height of at least 0.38 cm; and calculating the volume of binding material needed by solving the following system of equations: volume of binding material needed=(((binding material application rate)(percent binding material residuum))−amount of binding material adsorbed)(1000cm 3 /L); volume of total air voids=(percent aggregate mixture air voids)(crack resistant layer thickness)(1 m 2 )(100 2 cm 2 /m 2 ); AVFA =(volume of binding material needed)(volume of total air voids); and substantially voidless layer height=(crack resistant layer thickness)( AVFA ); applying the aggregate mixture within 15 seconds of applying the binding material to the surface, where the aggregate mixture comprises aggregate particles and an asphalt solution and where the aggregate mixture has a plurality of air voids; and allowing the binding material to fill some of the air voids in the aggregate mixture to form a substantially voidless layer with a height of at least 0.38 cm.
