To estimate the design traffic on a pavement requires several inputs from the traffic engineering department and to assign a desired pavement life. There are several ways to determine the …

Assuming that traffic is equal in both directions, Table 5.1 provides a guide to estimating the design traffic. Table 5.1: Estimation of design traffic from AADT for single carriageways. If not …

The design traffic calculated in terms of ESA of loading is converted to SAR of loading using the average SAR/ESA value for each damage type. These factors are determined from the Traffic …

DESIGN STEP 1: Calculation of cumulative number of Heavy Vehicle Axle Groups (NDT ) (i) The initial daily heavy vehicles in the design lane calculated as: Ni = AADT × DF × % HV/100 × …

determination of design modulus from measured modulus. A worked example illustrating the construction of a master curve from test data, and subsequent determination of the design …

In order to design a flexible pavement first need to determine the Design Traffic (in DESA) from Design Traffic (NDT). The formula to estimate the Design Traffic (NDT) is: (From Lecture 10, …
