I-65 In-situ Pavement Evaluation (FWD) and Cross Drain Testing--Federal Aid Research Task No. 117

Kentucky is currently working toward widening and rehabilitating the 1-65 interstate corridor. To assist in the roadway design process an evaluation ofthe existing pavement and roadway conditions is necessary. Two of the major components of this effort are determining the in-situ pavement conditions through non-destructive testing utilizing the Falling Weight Deflectometer and determining the condition of the roadway cross drains and culverts. The evaluation of the culverts and cross drains is necessary to determine to what extent replacement or reconstruction of these structures is necessary. The presence of clogged c:rossdrains may induce excessive amounts of subsurface moisture into the pavement structure, which leads to poor pavement performance. Center personnel have reviewed plans for approximately 73 miles of the corridor;
