The AASHO road test was probably the most significant piece of pavement research performed in the 20 th century. The results of the AASHO road test have served as the basis for nearly all subsequent pavement designs used in the original construction of the interstate highway system (IHS) after 1961. When considering the overall performance of HIS pavements, we find that most of the pavements have lasted the expected 20 years while carrying traffic volumes far in excess of those predicted at the time of design. ![]() The AASHO road test, possibly the largest and most successful controlled civil engineering experiment ever undertaken, was conducted about 50 years ago. The results of the study are still widely used across the world. PAVEMENT DESIGN AASHTO METHOD PROPOSALS SOFTWARE.
