Abstract: Materials for expedient roadway pavement repairs must provide a trafficable repair in a minimal amount of time. Therefore, any repair material must be able to cure quickly and be easy to use. There are a large number of proprietary cementitious rapid repair materials for both asphalt and concrete pavements. Three types of cementitious materials were used to make acceptable expedient repairs to an asphalt roadway. Trafficking showed that these materials were not flexible enough to provide durable repairs to flexible pavements in hot weather. There are a number of proprietary asphalt based repair materials. These materials can generally be trafficked immediately after placement with some displacement, depending upon the loads. These products will gain more stability with time and with cooler temperatures. Repair materials using cut-back asphalts generally provide the best combination of workability and long-term storage under adverse conditions, particularly freezing temperatures. This study evaluated the asphalt repair materials for workability, strength using Marshall stability and triaxial testing, and durability in regards to cohesion and adhesion properties. The majority of repair materials use an open-graded mixture and the Marshall stability test is not appropriate for this type of gradation. The proprietary cold mixtures were all easier to apply and work with than the conventional cold mix. The products that advertised placement into wet holes all preformed well and provided equal performance in both wet and dry holes for the traffic and evaluation period used.
