Some Aspects of the Construction of the Azraq to Jafr Highway Project in Jordan

Hot desert environments with low humidity and strong winds provide some of the most difficult conditions in which to build good concrete roads. This paper briefly describes the materials, plant and some of the methods that were used to successfully construct the Azraq to Jafr highway in Jordan where these conditions prevailed. Of particular importance to the outcome of the project were the use of good quality materials and the most suitable concrete mixing and paving plant available together with the adoption of very effective curing procedures. An interesting aspect of the pavement was the complete omission of expansion joints.
