Abstract

The paved and graded roads in Oman within the concessionaire area of Petroleum Development Oman (PDO) are 520 and 6,000 km, respectively. PDO constructed experimental sections in Southern Oman, the objective being performance improvement of graded roads using a sulphonated petroleum product (SPP) as a stabilizer, and evaluate slurry seal and double sand seal surfacing applications. Each type of surfacing had SPP-base layer. The control section was unpaved with unstabilized base. Field monitoring was from June to November 1996 and continued from April to June 1997. Evaluation was based on visual assessment, riding quality, rutting, and strength. The results showed that the un-surfaced sections were not serviceable at the end of the evaluation period. The slurry seal section with SPP displayed the best overall performance during the total study period. Nevertheless, it became evident that this type of surfacing will have a limited service life of 3-5 years. The laboratory investigation showed that CBR after stabilization was more than twice of the normal aggregate.
