Portions of the driving lane on I-76 located in CDOT's Region 4 are seriously distressed. To help prolong the life of the Portland Cement Concrete Pavement Region 4 has placed signs advising truckers to use the passing lane between Roggen and the Nebraska state line approximately 140 miles. According to a survey conducted by the Colorado Department of Transportation, 90% of the total truck traffic is concentrated in the driving lane. Both lanes are subjected to the same environmental stresses but the driving lane has become prematurely distressed due to the damage caused by the heavy truck loads. A test section well within the signed test area advising the truckers to use the passing lane and a control section just prior to the signed area were established and evaluated over a four year period. Roughness data taken with an Ames Profilograph, slab faulting measured with a Georgia fault meter, and overall physical pavement distress were noted and used as a comparison between driving lane and passing lane within the two sections.
