SCRUB SEALER COMPOSITION, METHOD, AND APPLICATION BOX
This disclosure relates to a method of preparing a scrub sealer. The method includes preparing an asphalt emulsion, and preparing a premixture of at least two different types of aggregate. The method also includes passing the asphalt emulsion and the premixture through a mixer to form the scrub sealer.
1 . A method of preparing a scrub sealer, comprising:
preparing an asphalt emulsion;
preparing a premixture of at least two different types of aggregate; and
passing the asphalt emulsion and the premixture through a mixer to form the scrub sealer.
2 . The method of claim 1 , wherein preparing the asphalt emulsion includes mixing at least water, a surfactant, and asphalt together.
3 . The method of claim 2 , wherein preparing the asphalt emulsion includes:
heating the water to about 85-160° F.;
mixing the surfactant with the hot water to form a solution;
heating the asphalt to a temperature of about 275-325° F.; and
mixing the hot water together with the solution to form the asphalt emulsion.
4 . The method of claim 2 , wherein the asphalt is a minimum of 65% of the emulsion.
5 . The method of claim 2 , further including mixing a polymer together with at least one of the solution, the asphalt, or the premixture.
6 . The method of claim 5 , wherein the polymer includes a latex.
7 . The method of claim 6 , wherein the latex includes at least one of SBR, OPE, SBS, natural rubber, or neoprene.
8 . The method of claim 5 , wherein the polymer is 5-10% of a residue of the emulsion.
9 . The method of claim 5 , wherein preparing the asphalt emulsion further includes mixing a rejuvenator together with the polymer, the water, the surfactant and the asphalt.
10 . The method of claim 9 , wherein:
the rejuvenator includes at least one of petroleum, vegetable biomass, vegetable oil, or recycled cooking oil; and
the rejuvenator is 2-10% of the total emulsion.
11 . The method of claim 9 , wherein:
the asphalt is a minimum of 65% of the emulsion;
the polymer is 5-10% of a residue of the emulsion; and
the rejuvenator is 2-10% of the total emulsion.
12 . The method of claim 1 , wherein:
preparing the premixture includes mixing the first type of aggregate with crumb rubber; and
the first type of aggregate includes at least one of crushed stone, RAP, carbon black, recycled plastic, clay or slag.
13 . The method of claim 12 , wherein:
the first type of aggregate has a size of about ⅜″ or less;
the crumb rubber has a standard mesh size of 4-40; and
a weight of the crumb rubber in the premixture is 10-20% of the weight of the first type of aggregate in the premixture.
14 . The method of claim 1 , further including loading the asphalt emulsion and the premixture onto a mobile machine, before passing the asphalt emulsion and the premixture through the mixer.
15 . The method of claim 14 , wherein the mixer is located onboard the mobile machine.
16 . A method of sealing a road using the scrub sealer from claim 1 , the method of sealing comprising:
pouring the scrub sealer from the mixer into a scrub box towed by the mobile machine; and
using rows of brushes in the scrub box to scrub the scrub sealer into cracks in the road.
17 . The method of claim 16 , further including applying a road paving system different from the scrub sealer over a layer of the scrub sealer.
18 . A scrub sealer as prepared via the method of claim 1 .
19 . A scrub sealer, comprising:
an asphalt emulsion, including:
water;
surfactant;
asphalt; and
polymer; and
an aggregate premixture, including:
a first type of aggregate; and
a crumb rubber.
20 . The scrub sealer of claim 19 , wherein the polymer includes at least one of SBR, OPE, SBS, neoprene, natural rubber, acrylic, or vinyl.
21 . The scrub sealer of claim 19 , wherein the polymer is 5-10% of a residue of the emulsion.
22 . The scrub sealer of claim 19 , wherein:
the asphalt emulsion further includes a rejuvenator; and
the rejuvenator includes at least one of petroleum, vegetable biomass, vegetable oil, or recycled cooking oil.
23 . The scrub sealer of claim 22 , wherein:
the asphalt is a minimum of 65% of the emulsion;
the polymer is 5-10% of a residue of the emulsion; and
the rejuvenator is 2-10% of the total emulsion.
24 . The scrub sealer of claim 23 , wherein:
the first type of aggregate includes at least one of crushed stone, RAP, carbon black, recycled plastic, clay or slag;
the crumb rubber has a standard mesh size of 14-40; and
a weight of the crumb rubber in the premixture is 10-20% of the weight of the first type of aggregate in the premixture.
25 . The scrub sealer of claim 24 , wherein the weight of the crumb rubber in the premixture is 10-15% of the weight of the first type of aggregate in the premixture.
