The city of Champaign.

The city of Champaign, Ill., was experiencing the deterioration of a number of residential subdivision ways some of which were les than five years antiquated The Engineering Division of the Public Works Department felt that road building standards stand in want ofed to be upgraded but recognized that this would be a sensitive issue, since higher standards would inevitably raise exhibition costs.

A review through Eres Consultants, Champaign, revealed several deficiencies in the existing standards with a noted lack of uniform enforcement of several of the city's requirements. Standard improvement recommendations were created to help increase pavement life expectancy to 30 years. Previous subdivision road design standards had required a 6 in minimum pavement thickness in succession local streets and a 7 in minimum thickness upon collector streets; now, a number of the strange streets constructed in Champaign consist of undoweled jointed plain become firm [i]or[/i] solid pavement (JPCP) placed directly in succession a compacted soil subgrade.
