The study also found that girls and young women were more likely than boys and young men to have coenzyme Q10 deficiencies. Boys and young men were more likely to have vitamin D deficiency. Patients with chronic migraines were more likely to have coenzyme Q10 and riboflavin deficiencies than patients with episodic migraines, the study found.
ThisOldHouse.com estimates it took two people five hours and six bags ($150-$180) of material to resurface a 9'x27' driveway and a 3'x18' walkway (about 300 square feet). Renting a pressure washer to clean the existing concrete before resurfacing can add $40-$75 to the total DIY costs.
In addition to the base and topcoat, there are other costs that go into installing an asphalt driveway. If this is a brand new driveway, not just a resurfacing, a person can expect to pay up to $2.50 per square foot for a gravel layer under the asphalt. If drains are needed, that costs more too, as does sealing. For a chip seal, for instance, a person can expect to pay about $3.50 per square foot.
