“…Hence, the total amount of traffic that the pavement is subjected to over its life since last laid down is a very significant determinant of the pavement condition [Sharaf and Sinha 1984;Fwa and Sinha 1988]. Traffic, anywhere, is far from being homogeneous (that is, normally composed of small passenger vehicles, pick-up trucks, buses, trucks and tractor-trailers , and so on).…”

“…Earlier studies [Sharaf and Sinha 1984;Al-Suleiman and Sinha 1988] Since the line demarking the boundaries of the two climatic regions does not neatly follow the boundaries of the districts, the subdistricts were treated as "nested" factors within the climatic regions, with the intent of using "contrasts" for comparison of district to district variations. All other factors were considered crossed with each other.…”

“…In this current study, the annual traffic was first obtained for each link from the INDOT's traffic reports; the traffic data were then converted into ESAL using an established procedure [Sharaf and Sinha 1984]. The annual ESAL values were then summed over the life of the pavement (since last resurfacing)…”

“…As to the quantification of the impact of maintenance activities on pavement serviceability, three different approaches have been used: one related roughness to maintenance effort [Sharaf and Sinha 1984] ; another related change in roughness to maintenance effort [Al-Suleiman and Sinha 1988]; and the third, in terms of PSI-ESAL Loss [Fwa and Sinha 1988].…”

Prepared in cooperation with the U.S. Department of Transportation, Federal Highway Administration. AbstractThis study covers pavement surface maintenance on three surface types: rigid, flexible and composite (asphalt overlay on rigid pavement).It addresses 3 main ir.sues as follows:1) Do routine maintenance activities make a difference in terms of pavement serviceability? If yes, how much? 2) Are chip and sand seal coating costeffective? What is their optimal timing? 3) What management criteria should be used as a guide to make seal coating decisions on specific roadways? In resolving Issue #1, a stratified 2-stage sample of observational data was used in a statistical before/after comparison.SAS-General Linear Model was used due to its flexibility in treating continuous and class variables. Most activities showed significant effect (either alone or in combination with others) on Pavement Serviceability Ratings or Roughness Numbers.In resolving Issue #2, Life Cycle Cost Analysis was applied using agency and user costs. Results showed that optimal timing for seal coating is in the PSI range of 3.0 to 2.7, dependent on AADT.In resolving Issue #3, a literature search, telephone interviews and expert opinion survey were used to augment the findings on Issue #2 in generating a decision tree. The developed tree uses the available data at INDOT, although surface distress related criteria would be superior.The tree helps analyze the likely cause of distress, the preferrejd solution and a priority ranking in the case of funding shortages.Specific guidelines or the use of chip and sand seals are also provided.
