From the Editor
While North Americans take pain at the pump, there might be a little pleasure in knowing that the price isn’t $8/gallon ($2/L) like Europe. Filling a tank there thins the wallet by $125. Since it also requires crude oil, asphalt pavement is experiencing record prices here, bringing much pain to already stressed municipal street budgets. - On page 6

PICP Maintenance
Like all permeable pavements, PICP surfaces can become clogged with sediment over time, thereby reducing its infiltration rate. The rate of sedimentation depends on the amount of traffic and other sources that wash sediment into the joints. Sediment sources can be eroding soil, leaves, mulch and debris deposited from vehicles. - On page 16
