INFILTRATION PROPERTIES OF ROAD SURFACE MATERIALS

In recent years there has been considerable debate as to the quantity of water entering a pavement through the road surface. In response to this, an investigation was carried out by the staff of the Main Roads Department, Queensland to determine the factors influencing the infiltration properties of bituminous surfaces, especially asphaltic concrete surfaces. The investigation consisted of a theoretical study into the pumping effect of traffic, a laboratory investigation into the effect of various properties and a field investigation into the infiltration properties of "in service" pavements. In this paper the effect of air content on the permeability of asphalt has been determined for two design mixes. In the field investigation, a constant head permeameter was used to determine the infiltration rate at a range of heads. A discussion is given as to the likelihood of water entering a pavement under the combined effect of traffic and infiltration under a small head (a). The number of the covering abstract of the conference is TRIS No. 368448. (TRRL)
