Chapter 4 Thickness Design - APAI
Thickness Design4-1 Chapter 4 Thickness DesignGENERAL CONSIDERATIONSS everal procedures can be used to calculatethe Thickness of the proposed asphaltpavement. All are based on the volume andweight of the traffic that will use the facilityand on the load-supporting capability of theunderlying AASHTO Road Test and other studieshave indicated that heavy-vehicle wheel loadscause much greater damage to roads than dolight loads. Thus, where large volumes oftraffic with heavily loaded trucks are antici-pated, an in-depth analysis of the pavementthickness is important. Because all of thehigher functional classifications have thepotential for heavy loadings, a traffic analysisis an important part of the preparation forthickness computations. Similarly, a know-ledge of the load-bearing capability of the soilis an important aspect of the structural designprocess.
Most trips on residential streets are short, and traffic volumes are low. Truck traffic is usually limited to vehicles that provide residential services such as trash pickup, moving vans, heating oil delivery, etc. Table 4-1.Thickness Design: Residential Streets A.
