FREEWAY WATER PROBLEMS TAMED
The paper reports how filter blanket system prevents groundwater intrusion in California highways. The blanket system consists of a 3-in.-deep gravel filter layer on the bottom, a 5.4-in. cement-coated pea gravel drainage layer, a 2.4-in. apshalt layer, and 8.4 in. of concrete pavement on top. The filter layer prevents soil from washing into the pea gravel drainage layer, which will channel groundwater horizontally to drain pipes.
