POROUS ASPHALT AGAINST WATER NUISANCE: APPENDICES A&B
Investigations are reported which attempted to: (1) find the relation between friction and water depth for several types of surfacing and various speeds, and (2) study the drainage properties and storage capacity of porous asphalt as a function of the crossfall, the rain intensity and the duration of the showers of rain. In the first investigation the types of surfacing considered were open-textured asphaltic concrete, synthetic resin surface dressing gritted with 5/8 mm crushed gravel, synthetic resin surface dressing gritted with 5/8 mm round gravel, synthetic resin dressing ungritted, and porous asphalt. The water depths, measuring device, and the details of the study are briefly outlined. In the second investigation, the equipment consisted of a 15.00 m long and 1.00 m wide channel which can be tilted to a crossfall of up to 10 percent. In the test program, the crossfall varied between 0 and 5 percent. The results of the study are graphically represented.
