Cloverleaf Streets Reconstruction

Phases 2, 3, and 4 Houston, TX

Costello provided design and construction phase services for the reconstruction of 16 asphalt streets in the Cloverleaf subdivision in eastern Harris County.

The area is a mature residential area with existing asphalt streets and roadside ditch drainage systems. There are scattered commercial development establishments within the area. The roadways were duplicated with respect to asphalt paving widths, elevations, and materials. Those streets include Frankie Blvd., Beacon St., Cloverleaf, Nancy Rose Blvd., Manor St., Nimitz St., Muscatine St., McNair, and Garber Lane. The improvements for each identified street included:

Strip vegetation and material from the edge of existing pavement
Mill off existing asphalt surface from the roadway (anticipated 3”)
Stabilize the remaining base materials (to a depth of 10”)
Apply a prime coat
Apply Hot Mix Hot Laid Asphalt Concrete Surface (2 – 1 1⁄2“ lifts )
Dress up Shoulders with previously milled asphalt
Place pavement markings on the new surface
Provide Traffic Control and Stormwater Pollution Prevention during construction
