| 摘要： | The durability of hot mix asphalt concrete (HMAC) overlays is important to the Oregon Department of Transportation (ODOT), as this is the most common form of surface rehabilitation on state roads. To see if several HMAC additives available in Orgeon increased overlay life, test sections were paved in 1985. The eight test and two control sections are located on US Route 97, 31 km (19.25 m) south of Bend, Oregon. The top course is a 38-51 mm (1.48-1.99 in) thick lift of HMAC, using the experimental additives. The combined base and leveling course is a 102-114 mm (3.98-4.45 in) thick lift of HMAC, using a combination of aggregate treated with lime and Pave Bond asphalt additive as anti-stripping treatments. The pavement under the overlay was badly alligatored and had frequent thermal cracks. |
