In order to analysis the capacity of one highway runway in north, according to the type of main landing gear and its glide trajectory transverse distribution, and considering about the distribution of car wheel trace, field test scheme is put forward. Heavy weight deflectmeter method and bearing plate method is tested in field test, according to comparative analysis the correlation of deflection between this two methods is found, the results correlate well with related research in highway, at the same time, the results show that dynamic modulus is about double of static modulus. According to the civil aviation specification method with heavy weight deflectmeter test results to calculate the pavement classification number as pavement bearing capacity evaluation results, and the equivalent pavement residual multiplication of cumulative of this highway runway is 33368188.
