Guidelines for Satellite Studies of Pavement Performance


Book Description

Guidelines to utilize the research findings from the AASHO road test at Ottawa, Illinois, are presented. The guidelines present a method of studying the interrelationships of performance variables and design variables of selected pavement sections so that comparisons may be made. 3 types of design variables are discussed: the structural variable which describes the strength characteristics of pavement layers, the load variable reported in terms of accumulated axle loads, and the climatic or regional variable which describes external influences.
















Measurement of Pavement Thickness by Rapid and Nondestructive Methods


Book Description

The feasibility is investigated of various acoustic (sonic), nuclear, and electrical techniques for nondestructive measurement of Portland cement and bituminous concrete pavement thickness both during and after construction. Recommendations are made for equipment development and field testing of three specific methods that could potentially result in such measurements with the desired degree of speed and accuracy.

Economics of Design Standards for Low-volume Rural Roads


Book Description

he objective of this study is to examine prevailing rural design standards to determine their economic justification. This would evaluate in depth the cost of some of the most significant design practices (for example, roadway and shoulder width and surfacing type). Resulting user benefits, such as operating, accident and time savings would be weighed against the cost of individual features. In addition to the analysis of the user-benefit relationships, the economic and social consequences to local residents, businesses and communities should be studied and a suitable means of including them in the reckoning of warranted levels of improvement should be found.
