Porous Pavement for Control of Highway Runoff
A three-lane by 3500 linear feet portion of an urban highway was constructed of porous pavement. The design resulted from a research study of the use of porous pavement to provide highway drainage. It was determined that after two years of observation, the porous pavement is working as designed. Pavement deformations as measured in wheel tracks from a straight edge and from pavement elevations measured at the completion of construction are not severe or abnormal. Slight deformation in control sections of conventional pavement occurred immediately after opening to traffic and have undergone no significant change since then. Deformation in the experimental porous pavement is slightly more and occurred over a somewhat longer period than for the control sections. Measurements indicate an increase in moisture content of the subgrade at one location in the porous pavement, but little or no change at the other locations monitored. The increase occurred during the first four or five months after the pavement was put into service. The condition of both the control and experimental pavements are excellent at this time.
