From the Lawrence Daily Journal-World for March 31, 1975:

Two engineering technicians, stationed at the Lawrence office of the state highway department, told the Journal-World today that they had witnessed improper road construction practices in three separate instances during the previous fall on U.S. 59, south of Lawrence. A third technical engineer said more than half the road had been put down in mud. The work the men discussed had involved laying asphalt on a subgrade they said was too wet, and using machinery which one said had not been state-approved to pour concrete. One of the engineering technicians said “almost the whole road was put down in mud” and that many furrows made by trucks in the soft ground had not been repaired before the asphalt was put down. According to David Darwin, assistant professor of civil engineering at Kansas University, the subgrade was required to meet compaction requirements. “Certainly if the weight of the trucks was enough to make any noticeable deflection in the subgrade, then it no longer meets state requirements,” Darwin said.
