Description:

A project on I-70 from Copper Mountain to Silverthorne began to exhibit moisture related distress after one severe winter. The European testing equipment was used to improve the quality of the hot mix asphalt (HMA) pavement. The primary reason the Colorado DOT and the FHWA Turner Fairbank Highway Research Center obtained the equipment was to improve the quality of HMA pavements. The purpose of this report is to document a case history of the use of the European equipment to improve an HMA pavement on a project in Colorado. Cost effective adjustments were identified to produce a high quality pavement that resists rutting and stripping. The three changes were: 1) increasing the optimum asphalt content, 2) adding a liquid anti-stripping additive with hydrated lime, and 3) changing the crude oil source and refinery. The cost of the HMA increased from $24.00 to $25.00, 4.2%, for a project cost increase of $80,000. These changes likely saved $5,000,000.
