“…The effective asphaltic relative strength coefficient, s 00 AC ðnÞ; can be determined based on both destructive and non-destructive testing of the pavement structure (Hong, 2014;Huang, 2004;Jimoh, Itiola, & Afolabi, 2015). State highway agencies typically use the falling-weight deflectometer (FWD) procedure to obtain an estimate of the effective relative strength coefficient as a function of the effective resilient modulus, which is normally estimated from the backcalculation of the multi-layered linear elastic theory (Gedafa, Hossain, Romanoschi, & Gisi, 2010;Hoffman, 2003;Sarker et al, 2015;Smith et al, 2017). However, local governments do not typically have access to the deflection instruments needed to carry out the FWD procedure; therefore this paper proposes a simplified approach to estimate the effective asphaltic relative strength coefficient as outlined in Equation 7.…”
