Porous Asphalt Concrete Pavement featured with Noise Deduction and Drainage Efficacy

The porous asphalt concrete (PAC) pavement was applied from Section 1 of Jianguo North Road, from Bade Road to Changan East Road (next to Taipei Municipal Zong Shan Girls High School), as a trial run. The high porosity of PAC can increase the permeability of pavement in raining days, avoiding forming water film that can affect the tire traction. This not only increases the car safety, but also reduces noises created by the interaction of tire and pavement. The pavement can therefore be applied on roads with big traffic or fast traveling vehicles, helping to reduce noises that disturb the neighborhood.

Porous asphalt concrete literally means asphalt concrete that features with higher porosity than ordinary ones. PAC adopts open graded and high viscosity modified asphalt that enable the porosity of pavement reaches 20% while reaching the carry capacity of ordinary graded asphalt concrete.

It is suggested that citizens can observe the benefits of PAC in terms of rainwater permeability by comparing it with ordinary asphalt concrete and experience the slide-preventing function of fPAC in person. At the moment, the New Construction Office has applied porous asphalt concrete on Section 2 of Chenggong Road (Neihu District), Minquan East Road (Zhongshan District, next to Hsing Tian Kong), Section 1 of Jianguo North Road (next to Taipei Municipal Zong Shan Girls High School) and Shuiyuan Expressway (from Fuhe Bridge to Jingfu Ramp) of Taipei City as a trial run.
