Ride on the part of the road that has been packed down or swept of most of the loose stuff by car tires, usually the wheel tracks. Stay out of mounded stone and move to another line immediately when the wheels become noisy (ie acoustically or vibration). If you do find the front wheel plowing, resist the urge to decrease pedal speed or add braking, that will only make the yaw worse. Add power to keep the front light and find a better line with gradual counter/steering inputs. Sometimes, the best place to ride on a rough road is on the edge; not usually the case with chip seal as the excess is pushed to the sides. That said, when it comes to rough roads, road bikes and going as fast as you can, you gotta think outside the box.
