POROUS PAVEMENT FOR THE CONTROL OF HIGHWAY RUNOFF. FIRST ANNUAL MONITORING REPORT

A three-lane by 3500 linear feet portion of an urban highway was constructed of porous pavement. This design resulted from a research study of the use of porous pavement to provide highway drainage. It was determined that after one year of observation, the poruous pavement is working as designed. Although the rainfall during the year was slightly more than the typical annual rainfall, there were no storms approaching the ten-year design storms to obtain a full test of the capacity of the system. Pavement deformation as measured in wheel tracks from a straightedge 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.
