Seal Coat and Surface Treatment Manual: Selection of Aggregate

Anchor: #i1000127 Section 2: Functions of Surface Treatments and Seal Coats Anchor: #i1000132 General. A surface treatment is placed on a crushed stone base to provide a roadway with the least expensive permanent type of bituminous surface. It seals and protects the base and provides strength at the road surface so that the base can resist the abrasive and disruptive forces of traffic.

hydraulic conductivity of crushed stone

 · For well graded, compacted crushed aggregate it seem very unlikely that it is as high as 50,000 in/hr. An infiltration rate ( not K) of 1-inch per hour would be considered very well drained. 50,000 in/hr corresponds to a velocity of about 1.15 feet per second. This seems very fast even for groundwater in a good, porous, aquifer.
