Page 3: 300.1 Introduction
300 Rigid Pavement Design 300 Rigid Pavement Design 300.1 Introduction Rigid pavements can be constructed with contraction joints or no joints, with dowels or without dowels, and with reinforcing steel or without steel. For jointed concrete pavements, regardless of whether reinforced or non-reinforced, the AASHTO/ODOT method of pavement design calculates the same required thickness. -
Page 4: 301 Design Parameters
300 Rigid Pavement Design 301 Design Parameters ODOT's method for the design of rigid pavement limits the designer to prescribed input parameters. The input values prescribed are based on Ohio materials and ODOT Specifications. 301.1 Modulus of Rupture Modulus of rupture, as determined under a breaking load, measures the flexural strength or extreme fiber stress, of the concrete slab. -
Page 5: 301.6 Effective Modulus Of Subgrade Reaction
300 Rigid Pavement Design 301.6 Effective Modulus of Subgrade Reaction The effective modulus of subgrade reaction (k) is the composite modulus of subgrade reaction as modified by the loss of support. Figure 301-3 is a nomograph that determines the effective modulus of subgrade reaction. -
Page 6: 303.3 Longitudinal Joints
300 Rigid Pavement Design To control pressure buildup, expansion joints and pressure relief joints are used. The most common need for an expansion joint or a pressure relief joint is to protect bridge back-walls. Four types of pressure relief joints are detailed in the Standard Construction Drawings. For new pavement construction, the Type A joint should be provided at all bridge approaches where the bridges are over 300 feet (90 m) apart. -
Page 7: 303.6 Edge Course Design
300 Rigid Pavement Design complexity of construction. Tying concrete shoulders to the driving lanes provides lateral support and spreads the load over a greater area. Concrete shoulders should use non-reinforced concrete even if the driving lanes are reinforced. The plans should include a note modifying the transverse joint spacing of the non-reinforced shoulders if tied to reinforced driving lanes. -
Page 8: 304.5 Class Of Concrete
300 Rigid Pavement Design 304.5 Class of Concrete Class QC1 is recommended for all mainline, shoulder, and ramp concrete in excess of 250 feet (75 m) of continuous pavement. Class QC MS or QC FS may be used for smaller, repair-type areas. These mixes are intended for joint and crack repairs or individual slab replacements. - Page 9 300 Rigid Pavement Design 307.2 Composite Pavement Typical Section Design Composite pavement should be constructed using Item 305 Concrete Base. The width of the concrete base should be extended beyond the wearing surface by 3 inches (75 mm). Item 409 Sawing and Sealing Asphalt Concrete Pavement Joints is recommended for most newly constructed composite pavements.
