Engineering Standards
B. Pavement Design Catalog is provided for each of the two main soil formations in Frisco: the
Eagle Ford and the Austin Chalk. Adequate testing is required to determine which soil formation
the project site lies within.
C. The Pavement Design Catalog is based on the data contained in Table 3.1. Any alternate designs
shall be based on the same data.
D. All concrete for paving shall be Class C unless otherwise approved by the Director of
Engineering Services.
E. All concrete which comes into contact with soils containing more than 0.1% (1,000 ppm) sulfate
shall be designed to resist sulfate attack.
F. All asphalt shall be Type C.
G. Reinforcement shall be no less than #4 bars on 18” spacing.
H. Within the Pavement Design Catalog, the following applies :
1. Each option correlates to a specified range of swell potential.
2. Layer thickness is shown in inches and is not to scale.
3. Thoroughfare classes correspond to a specific range of average daily traffic (ADT).
4. For simplicity, Options 2.1-2.6 only show Type A & B Thoroughfares since Types C-G
Thoroughfares will not incorporate a nonwoven geotextile interlayer and CTB. For Types C-
G, use Options 1.1-1.6
