In concrete pavements with uniform tining space, the whine noise which has high frequency spectrum related to the uniform tining space exist. In this paper, randomization procedure of tining space for concrete pavements is proposed. The proposed procedure developed based on the LCG(Linear Congruential Generator) algorithm. And the factor concerned in the procedure are drag span length, number of different tining space, ratio of each tining space, total tinings of each size, sequence of actual tining.

When driving on uniformly tining concrete pavement road, the whine noise which has high spectrum at the specific frequency related to the uniform tining space exist. In this paper, a randomization method of tining space for concrete pavements is proposed to reduce the whine noise. The proposed method is developed based on the LCG(linear congruential generator) algorithm. The design parameters used in the method are number of different tining space, ratio of each tining space, total linings of each size. sequence of actual tining under given constant drag length and texture. Monte Carlo simulations are used to validate the proposed method.
