Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. Unbound layer thicknesses are rounded to the nearest inch.Structural Behavior of Asphalt Pavements Book Description : 44(2.0) (5.5) (D3) D3 = 7.73 inches Use D3 = 8.0 inches for construction.1 1After rounding to the nearest half-inch, per the recommendations in the 1993 AASHTO Design Guide. AASHTO guide for design of pavement structures, 1993 by American Association of State Highway and Transportation Officials. From the City of El Paso and TxDOT guidelines, recommended base range 4-10 inches, Therefore D2 is equal to 5.5 inches Solving equation for subbase layer: 2.7=. For example, the basic 1993 AASHTO Guide flexible design equation is.

Values for design: a1 = 0.44, a2 = 0.14, and a3=0.11 Drainage coefficients mi for all unbound layers are set to 1.0įor the required overall structural number (SN) using software or excel solver: SN = 2.71.ġ2 Step 8: Determine the design layer thicknesses for the pavement section to apply to equation: From the City of El Paso guidelines, minimum HMA section (wearing surface) should not be less than 1.5 inches. All variability the pavement structural design process is then accounted for in the. Recommendations for appropriate ai values for design are given by 1993 AASHTO Design Guide.

Reliability = 80% (local urban traffic), ZR = standard normal deviate =, S0 = standard deviation = 0.45 (most commonly used).ħ Step 4: Determine the allowable serviceability loss due to traffic (ΔPSI) ΔPSI = 2.2 given by equation: ΔPSI = pt− po=4.2−2.0=2.2 Values most commonly used for pt and poĨ Step 5: Evaluate the seasonally averaged subgrade resilient modulus MR using the formula: MR = 2555*(CBR) 0.64 MR = psi.ĩ Step 6: Determine the layer properties: Values for design: EAL=Equivalent Axle LoadingĦ Step 3: Determine the design reliability factors: 1993 AASHTO Guide for Design of Pavement Structures The Vermont.

Part I Pavement design and management principles. (LEC):įor the design scenario, a 20-year design life is specified. AASHTO guide for design of pavement structures, 1993. All versions of the AASHTO Design Guide are empirical design methods based on field performance data measured at the AASHO Road Test inģ Design of a flexible pavement section requires the developers to establish a baseline scenario for the location where the pavement is going to be placed The steps in the 1993 AASHTO flexible pavement design procedure summarized below and are in the context of the baseline scenario presented by Licon Engineering Co. Approximately 80% of all states use the AASHTO pavement design procedures, with the majority using the 1993 version.
