Concrete doesn't absorb water like asphalt so traction
grooves are added to portions of roadways
made of that material.
Concrete roads get cars
Drive a car with bad shocks or haul a trailer down H-1 in the Kaimuki area, and the ride gets quite rhythmic. There's a long stretch of H-1 that's concrete instead of asphalt, and sometimes the vibration gets so intense that you think you have a flat.
bopping on H-1
Why does concrete ride so much differently than asphalt?
State highways administrator Pericles Manthos says it's not just because they're two different materials, but because the materials and methods of applying them have improved.
"You have two schools, one that likes concrete because it's long-lasting, and one that likes asphalt because it's easier to apply and repair," said Manthos.
"That section of H-1 was poured quite a while ago, when they were still pouring concrete in sections and leveling them with flat wooden screeds. Newer sections, like the current widening in Aiea, uses more sophisticated techniques, slip-forms that are ground down to make them more level."
Laying concrete is like laying bricks; the bucking motion comes from the subtle difference between the level middles of the sections and the slight angles of the joints. Laying asphalt is a more organic process; it smooshes out like pudding and forms a continuous layer that behaves more like a liquid than a solid.
Asphalt is also more porous and rain falling upon it tends to percolate away. Not so with concrete, which is why concrete road sections generally have traction grooves combed in with diamond-bladed saws.
Concrete is springier as well. Elevated sections, such as those on H-3, are actually bowed upward in the middle. This "deflection" is designed to level out under the concrete's weight and the weight of average traffic.
"When we measure the sprung beams on H-3 to see how they're doing, we can't have cars travelling on them, because the roadway actually bounces up and down like a rubber band," said Manthos.
Williams concert cancelled
The Hank Williams III concert scheduled for June 19 at World Cafe has been cancelled. Anyone holding onto a paid ticket should call MCM Productions at 593-0317 for a refund. No reason was given for the cancellation.
