I had a tar-and-chip driveway that was installed over 9 years ago. It was showing its age, and I’ve lost my constant battle with weeds that seem to find a way to grow back in sections every year. So today, I had a new one installed.
It started with the crew from Keystone Tar & Chip Paving first removing all visible vegetation, re-defining the edges along the lawn, leveling and grading the entire length of the driveway, then compacting the graded surface using a 5-ton vibratory combo set of rollers. They then applied a vegetation preventative on the compacted surface, and proceeded with the main job: two individual layers of chip seal consisting of first, hot liquid asphalt (or tar) at the rate of 1/2 gallon per square yard, followed by crushed limestone gravel (or chips) at the rate of 1 ton per 500 square feet. After each coating, the 5-ton vibratory combo rollers went over the newly applied layer for further compaction while workers manually fine-raked and brushed for an even surface. All these in about 5 hours.
They also gave me tips on what herbicides to use to prevent weed growth, and further enjoy the new driveway for at least the next decade.
