| 摘要： | The Novachip process, also known as ultrathin friction course, was developed in France in 1986. The process utilizes a single piece of equipment to place a thin, gap-graded hot mix asphalt (HMA) onto a relatively thick layer of polymer modified asphalt emulsion tack coat. Two Novachip projects were constructed in Alabama in 1992 to achieve the following objectives: (a) Document the materials and the construction procedures utilized in the construction of the Novachip surface course, and (b) monitor and evaluate the performance of the Novachip test sections at regular intervals for a period of three years. This paper gives the construction details and performance of Novachip after 4 1/2 years in service. service. |
