Step 2: Chip-Sealing
Workers will seal the road surface with a layer of
asphalt chips, which is a mixture of liquid asphalt
and stone.
To prevent asphalt from damaging vehicles, it is
blotted with a layer of stone dust.
There will be a rougher surface than usual during thisphase. Pedestrians and bicyclists should use caution.
This is a tempo rary condi t ion!

Step 4: Slurry Seal
The final travel surface is applied, a mix of crushed
stone and liquid asphalt.
The surface will have a slightly texturized surface,which will be smoothed out over time by traffic.
The new surface will have a slightly brownish tint for
several hours until it has cured. When it has cured,the material will darken to black.

Why was Cape Seal chosen for our
neighborhood?
Cape seal is ideal for residential neighborhoods that
call for a smoother texture than chip seal.
Cape Seal addresses fair-to-moderately crackedpavement, and provides a skid-resistant surface with
a long service life.
Cape Seal combines the advantages of two sealingpreventive maintenance methods.
Cape Seal minimizes water penetration, reducing
damage to the road bed.14

Why was Cape Seal chosen for our
neighborhood?
Finish and ride is similar to asphalt, but the price is
substantially lower, allowing us to improve more
neighborhoods every year.
Cape seal combines the durability of a chip seal with
the smoothness of a slurry seal.
Less expensive than patching only, waiting for 10+
years, and having to do a complete road
reconstruction or rehabilitation.
