AASHTO Subcommittee on Materials – Andy Mergenmeier. The Subcommittee on Materials (SOM) will be presented with the option to vote on a “provisional” pavement design guide. It is expected that this will be done by a special vote after information is presented to the SOM meeting in August 2007. NCHRP Pavement Research Overview – Amir Hanna

The superelevation rate is negligible in almost all urban areas. The side-friction factor is based on safety against skidding and level of discomfort, and can be determined from graphs and tables in the American Association of State Highway and Transportation Officials (AASHTO) “A Policy on Geometric Design of Highways and Streets”.

(AASHTO 2008). Over a period of approximately 10 years, the fundamental approach to pavement design has changed from a procedure that is modeled from the observed performance at test tracks constructed in the 1950s to one based on modeling the performance of pavement structures based on axle load spectra, climate, and intrinsic material properties.

The design reliability (R) is similar, in concept, to that in the current AASHTO Design Guide – the probability that the pavement will not exceed specific failure criteria over the design traffic. For example, a design reliability of 90 percent represents the probability (9 out of 10 projects) that the mean faulting for the project will not ...

AASHTO Guidelines for Development of Bicycle Facilities calls for minimum bike lane width of 4 feet but recommends an additional 1-foot offset from curb. Why can’t the minimum design values be attained? The proposed section provides for restriping only with no reconstruction or widening of street pavement.

5.1.1 The slab is designed using the AASHTO Load & Resistance Factor Design Method for transverse slab designs. 5.1.2 The top ½” of the deck on bridges with overlays, or the top 1” of the deck on bridges without overlays, is neglected as part of the effective depth to account for long-term wear and deterioration under service conditions.
