Rubblization is one of the surface preparation techniques before placing a Hot Mix Asphalt (HMA) overlay that involves breaking the Portland Cement Concrete (PCC) pavement into pieces. This paper describes the structural assessment related to the long term performance of rubblized concrete pavements in Iowa. The structural performance of seven representative in-service rubblized concrete paveme...

The article presents the results of experimental research thermophysical properties asphalt concrete various compositions based on oil bitumen and bituminous rock, which have been carried out laboratory unit LKT-1 using horizontal flat layer method. It is shown that use rocks in composition road makes it possible to obtain a material not only with best physical mechanical properties, but also l...

Using waste rubber in asphalt mixes has become a common practice in road construction. This paper presents the results of a study on the rheological characteristics of rubber-modified asphalt (RMA) concrete under static and dynamic loading conditions. A number of static and dynamic creep tests were conducted on RMA mix specimens with different rubber sizes and contents, and a series of resonant...
