On the other hand, if air voids fall below 3%, there will be inadequate room for expansion of the asphalt binder in hot weather and when the void content drops to 2% or less, the mix becomes plastic and unstable. While there are design considerations involved in a pavement from the geometric, functional and drainage aspects, the structural design indicates estimation of appropriate thicknesses of the pavement layers.

AL-ROUSAN Pavement Types 1. Once voids reach 8% or higher, you get interconnected voids which allow air and moisture to permeate the pavement which reduces the durability of the pavement. The manual also includes the results of theoretical and applied research conducted in recent years. Is the pavement structure (subgrade, subbase, base, and all asphalt layers) adequate to support the loads? There are three approaches in pavement design, namely the empirical approach (AASHTO 1993), mechanistic approach (Austroads 1992, Mohamed and Nofal 1997, Newcomb and Timm 2001, Masad and Scarpas.
