PERFORMANCE OF BITUMINOUS SURFACE TREATMENTS IN ALASKA

A detailed investigation of Bituminous Surface Treatments (BST's) has been completed which determines the probable causes of a number of failures. Results of a two-year study have isolated many of the causes of these failures and offer recommendations to improve the performance of BST's. Most of the failures studied can be attributed to improper construction techniques such as low asphalt content, dirty aggregate, construction during poor climate conditions or poor base. Other factors which were found to contribute to poor performance include construction after August 20, the use of "C" and "E" chip combination and the use of unsound aggregate. No significant differences in performance could be shown between RC-800 and CRS-2 or between pre-1974 and post-1974 asphalt cements. (FHWA)
